August 14, 1931.

Dr. P. H. Rolfe. _- -
Consultor Technico de
Agriculture do Z. edo Minas Geraes,
Vicosa, Brazil.

Dear Dr. Rolfes:

Probably for some time you have been wondering why you did not
hear from me, but I have delayed writing until I could make some
report on our examination of the seeds and oil of the samples which
you sent.

I thank you for your letter of May 27, in which you suggested
that I write to Dr. Carvalho in regard to the palm Oenocarpus batana.
Some years ago he visited m here on several occasions and I enjoyed
his visits very much. I was much interested in learning of his
establishment of an oil and fat laboratory in connection with the
National Agricultural College.

I have written at your suggestion an article on Sapucainha
for the Journal of the American Medical Association, but as yet I have
not obtained the necessary permission, either from the Bureau or
from the Department to publish it. Owing to the large number of
articles submitted to this Journal, it would probably be three or
four months after they received ny manuscript before ay article would
appear in print. If I succeed in getting permission to publish it,
I shall request the Journal to make some reprints for me.

The following results were obtained in the examination of the
several samples of seed:

Sample Shells Kernels rOil in Iod. No. (0c) 20
Kerqels 0

Carmargo No. 1 28.0 72.0 67e6 109 +63.7
L.S.A.V. No. 1 38.0 62.0 65*7 112.9 +65.8
N No. 2 38.9 61.1 66.5 114.8 +54.9
Jiquairi No. 1 38.5 61.5 65.1 109.9 +55.3 -
Manhuasau No. 1 34.8 65.2 63.7 109.8 +54.4-
Tocantius No. 1 34.3 65.7 68.8 114.4 +66.7 -
100-B 38.5 61.5 64.2 109.9 +54.6

T he optical rotation determined on a chloroform solution of the oils.

(Dr. P. R. Roife)

All the samples of oil had. to be obtained by extraction with
petroleum ether, as these small seed samples did not permit the ex-
pression of the oil. When circumstances permitted, we took about
120 grams of the seed for the determination of the proportion of shells
to kernels. It will be observed that in the case of sample L.S.A.V.
No. 1, that we obtained. 2.5 per cent less from the kernels than that
reported for the large sample last year. this may be due in part to
moisture changes in the shells and kernels, and in part to the difficul-
ty of sampling of these seeds. from the high specific rotation
figures alone for all the samples of oil it appears that there is but
very little choice between them,and this was expected because of the
very small range in the iodine numbers.

With best regards to you and Miss Rolfe, I remain

Very truly yours,

Mr. P. H. Rolfs,
Escola Superior de Agricultura e Veterinaria,
Vicosa, Minas Geraes, Brazil.

Dear Mr. Rolfs:

I have your letter of April 21. and appreciate very much
your efforts to secure the jaboticabas. I don't know of anyone here
who has any special knowledge as to how to prepare the seed. I am
wondering if, with the new air mail connections, a few of the fruits
could not be sent here. We would be glad to pay the packing and post-
age charges. I am enclosing a voucher to cover at such time as you
may be able to send them along. The same would be true of cuttings.

I am interested to learn that you are getting the first
fruits of Taraktogenos kurzii. I am enclosing a list of the distribut-
ions made between 1921 and 1925. We recently had occasion to check up
on a few of the places and when this information comes in, we will send
it along as well.

I am leaving Washington on the 25th for Spain and North
African. points with Mr. Westover. He will be working on alfalfa and
I will be working on some of the fruit varieties. I will also attend
the International Horticultural and Botanical Congresses in England
in August. I expect to return to this country along in October.

With best wishes, I am

'Very sincerely yours, /)

/ } Taraktogenos kural

The Taraktogenos have not done very well at Sumit. Up the
Ohagres River, where we have a plantation of about eight
acres of Taraktogenos, the trees have made a rather satis-
factory growth and have begun to produce fruit this year.

56633 Taraktogenos kurzii

Trees shipped in May, 1924. During January 1925, 300 of these
trees were lifted from the nursery and planted on the grounds
of the new leper colony. Up until the time of the hurricane of
September 13, 1928 the trees were growing very vigorously. The
terrific wind which blew for several hours snapped off the
terminal shoots of every chaulmioogra tree and left many of them
prostrate on the ground. Many recovered and most of them have
since sprouted.
A short time ago I made an inspection of the plantation and the
information you request can be given as follows:
1.- Number of trees living 200
2.- Average height 3 ft.
3.- Three specimens 12 ft.
4.- Many specimens 6 ft.
5.- None have flowered or fruited
6.- Soil a very tenacious, infertile clay.

The majority of the trees are healthy and I am sure
thrive. You will be notified when-they flower.

The Oncoba eohinata at Summit is doing very well and has
yielded fruit for several seasons. It seems to be better
adapted to the conditions there than any of the other
sources of ohaulmoogra or similar oils. It is also more
preoooious and produces rather freely.

April 30, 1930.

Dr. P. H. Rolfe, Consultor Technico
de Agriculture do Estado de Minas,
Escola Superior Ge Agricultura, e Veterinaria,
Vicosa, Minas Geraes, Brazil.

Dear Dr. Rolfe:

We have the following to report on the seeds and oil, from
Carpotroche tree No. 1:

Seeds: kernels 64.51% and shells 35.49%. '
Average weight of seed .653 grams.
Oil in seeds 40.91%; in kernels 63.42%. Kernels
contained 2.5% of moisture.

An examination of the cold expressed oil which has a pale
yellow color, gave the following results:

Acid Value o.4; Refractive index at 25 1.4792j
Specific rotation in chloroform (od) + 5g.9;
Saponification value 201.1; Iodine 1o. (Hanus) 108.6.

The oil is remarkably fine. The very low acid value indicates the perfect
condition of the seeds at the t ime the oil was expressed.

At first we attempted to express the whole seeds in our expeller,
but on account of the character of the shells, so much resistance occurred
that the machine quickly stalled. Then we cracked the seeds and separated
the kernels and expressed the oil without serious difficulty. From our ex-
perience in handling the seeds it would appear preferable to express the
oil on a commercial scale in the cage type of hydraulic press. I was much
surprised to find that the kernels had such a high oil content.

As yet the small sample of seed from tree No. 2 ha-s. not arrived.

Since writing last, I have examined the reference to which you
kindly called attention in Memorias do Instituto Oswaldo Crux and was
pleased to get the optical rotation of the oils from several species of
carpotroche plants.

I wish that G. Kuhlmann had also found and recorded the oil content
of the seed from each of those species. That would have been an important
addition. Perhaps you could call his attention to it.

' I


You will observe that the specific rotation of the oil which I
expressed is somewhat greater than that, recorded by him for C. brasiliensis.

With best regards, I remain,

Very truly yours,

G. S. Jamieson,
Chemist in Charge,
Oil, Fat and Wax Laboratory.

Dr. P. H. Rolps,
Escola Superior de Agricultura
e Vitertnaria,
Vicosa, Minas Geraes,

Dear Dr. Rolps:

In connection with the examination of the samples of Carpotroche
oil which you sent to Mr. Stevens in 1927, we obtained the following

Specific gravity at 25/25 0C. 9545; refractive index at 20 1.4812;
iodine numbers 102-10365; saponification value 202.51 unaaponifiable
matter 0.6 per cent; acetyl value 5.8; acid value 1.8; Reichert-Meissl
value 0.7; Polenske number 0.7.

The specific rotation (Si) 20 for the liter sample was +53-9"
and +54.90 for the second small sample. The characteristics as given
above for-both samples were practically identical, and I think this
proves the authenticity of the "liter sample" beyond a doubt.

I shall enclose a copy of a table that gives the more important
characteristics of the seed oils of the known numbers of the Flacour-
tiaceae, which contain chaulmoogric and hydnocarpin acids, or both*

The Gorli seed (Oncoba echinata) fat which we expressed from
seed grown in Costa Rica contained 4 per cent of moisture and 52*3 per
cent of fat, which melted from 42.8 to 430 C. The characteristics of
this fat were as follows -

Specific gravity at .9356; refractive index at 40* 1.4720;
iodine number 94.2; saponlfidation value 193.3; unsaponifiable 1.0 per
cent; acetyl value 3.7; acid value 6.0; Reichetl-Meissl value 0.;
Polenske number 0.3 and specific rotation (K() in a chloroform so-
lution was +49.460.

Goulding and Akers (Chem. Soc.Proc. 1913, 137) found seed from
Sierre Leone contained 47 per cent of fat, which gave an iodine number of
99.7, a saponification value of 192.4, and a specific rotation in a
chloroform solution at 18o of +48.8 .

I was indeed much pleased to have had a little visit from you

(Dr. P. H. Rolps)

and your daughter. on August 24, and I trust you had a pleasant voyage
on your return to Braszil.

If possible, I wish that pressure could be brought on the
Brazilian government as to the importance of properly classifying the
various carpotroche trees in order that such an investigation would
be undertaken in the near future., In case that suggestion fails, it
might be possible for the botanists in the United States Office of
Foreign Plant Introduction or other divisions of the Bureau of Plant
Industry, to undertake this investigation, providing they could be
supplied with sufficient botanical material for identification pur-
poses along with suitable photographs of the various trees&

In view of the high oil content of carpotroche seeds, I believe
that we could get along very nicely with 25 pound samples instead of
50 pound samples as I suggested when you were here. If possible,
when you send the seeds, I would like to get several specimens of
whole fruits for mn collection.

With best regards, I remain
Very truly yours, *':

Dear Doctor Rollfs:

I was very pleased to get your letter of October 5,
1929, and thank you for same.

From what you have written, it is' evident that
Carpotroche seeds have very good keeping qualftles. Your
Onchoba bushes certainly have been laying down on the job
this year, but perhaps they are somewhat young to become
regular producers of fruit.

I quite agree with you that an American explorer-
botanist, in cooperation with one or more designated by the
Brazilian Government, should undertake an extensive exploration
with the object of classifying the native members of the
Flacourtiaceae, even if this undertaking should require two
or three years. After careful consideration of the matter, it
would appear best in this connection for you to interest our
Office of Foreign Plant Introduction and get their views on a
joint expedition.

I shall be pleased to cooperate with you in any
way possible.

Very sincerely yours,

G. S. Jamieson,

Dr. P. H. iolfs,
Consultor Technico de Agricultura do Estado de Minas Geraes,
Viscosa, Minas Geraes, Brazil.

Dear Dr. Rolfsa:

Tour letter of November 21,1929, and the Carpotroche fruits
have been received, for which I thank you .. The fruits reached me in
perfect condition, and I assure you that I am much pleased to have them.

The desirability of an exploration in Brazil for Carpotroche
species and your interest in such an undertaking have been called to the
attention of Mr. E. P.'Killip and Mr. William R. Maxon, both of whom re
connected with the Smithsonian Institution, U. S. National Museum. Mr.
Killip has done considerable botanical exploration work in South America,
and only recently returned from the head waters of the Amazon. He spent
nearly eight months in Eastern Peru.

I have been informed that the Museum authorities have not planned
any addition. field trips to South America for the near future. Dr.
Blake, Economic Botanist, Bureau of Plant Industry, is rpuoh interested
in the Carpotroche, and has offered to study and classify any of the
species, known or new, providing sufficient botanical material was sub-
mitted to him* He stated that it is absolutely necessary to get flowers,
leaves, fruit, etc., from the same tree of each supposed distinct species
for such work; otherwise mistakes in classification are liable to be
made. If you could send the necessary material for identification pur-
poses from your tree No.2 Dr. Blake would be pleased to identify it. I
would also suggest that material from tree No* 1 be forwarded at the same

Since receiving your interesting letter Dr. Blake and I have been
occupied, as time permitted, in looking up the Carpotroche species that
have been described and listed in the Kew Botanical Index and elsewhere.
I am enclosing a photostat copr of a portion of Part 5, Volume 12, V.S.
National Herbarium publications, dealing with the Carpotroche species,
written by Henry Pittier, a Swiss botanist, who for some years has been
engaged in Venezuela in an investigation of the flora. I am also enclos-
ing a list of the various species of Flacourtiaceae to date that I have at
hand, which may be of some interest to you.

I have not been able to get any information relative to the oil
content of the seeds or the character of the %ils of any of the Carpotroohe
species other than from C. brasiliensis. There is tha pIssibility that

(Dr. P. H. Rolfs)

the seed of some of the other species may not contain optically activeI
oils, optical activity being, an indication of the quantity of cyclic
acids of the Chaulmoogric gr(up. Without doubt the 91i from the seeds)
of all species should be investigated, but the difficulty of securing
a suitable quantity of seeds from each species will probably delay
getting all the desired information for many years. However, I shall
do what I can to hurry the matter along.

I hope you can secure more information in Brazil in regard to
the chemist and his work on Carpotroche oils.

Do you know the age of your Taraktogenus kurzii trees that have
recently bloomed? Have you arny information in regard to the usual
age of these trees when they blossom in other countries?

If you can forward 200 or 250 grams of seed from tree No. 2 we
can determine the percentage of oil, and solvent extract a sufficient
quantity of oil to measure the optical activity to see how the oil
compares with the sample from C. basiliensis that we have on hand.

Wishing you and your daughter a Happy New Year, I remain

Sincerely yours,

G. S. Jamieson,

Dr. G. S. Jamieson,
Bureau Chemistry U. S. D. A
SWashington, D. C.
Dear Dr. Jamieson:

Your letter of March 20 was received on April 14.

I was very glad indeed to hear from you and know that the
sending of Carpotroche seeds was received in good order. Like you,
I am very much surprised at the very favorable results that you ob-
taned from these seed.
I hope shortly to send thru to you a kilo or so of seed
of Carpotroohe from quite a different looking tree. I believe I
have referred to it before as Tree N2 2.

In the bMemoirs do Instituto Oswaldo Crus, etc., you will
find the names of Brasilian chemists who are working on the arno -
troshe seed, You will also find an interesting list of seeds that
have been analysed for the presence of this oil.

In ease you have moreseed than you need for your experi-
mental work it might be a good idea to turn them over to some one
for germination in the green houses. If you do so, tell them that
it may take a very long tins for them to germinate. I had some of
them in the seed bed for more than a year and a half without thiar
germinating and yet they were in perfect condition for germination.
This tree grows at the frost line on account of our high altitude,
consequently it might be possible to utilize it even in South Vlorida.

I notice that in my former letter I misled you in regard
to Taraktogenus kursii blossoming at four years old. We brought
the plats with us from the green house in Washington in 1925# When
they were at least a year old, possibly older. They were then set in
a nursery row and four years from .the time they were plaited in their
permanent location they had bloom. This of course is a much shorter
time than wo had anticipated.

Vicosa, Minas Geraes, Brazil.

Dear Doctor Rolfs:

In reply to your letter of February 1, 1930, the 10 kilos
sample of Carpotroche seed arrived safely. Some examination of
the seed has been made, but due to a number of circumstances I
have not yet been able to undertake the expression of the oil.
However, I want you to know that I have the seed. They were found
to consist of 64.51 percent of kernels and 35-49 per cent of shells.
The kernels contain 63.4 per cent of oil and 2.5 per cent of mois-
ture. I was much surprised in that the seeds were so rich in oil.
The oil extracted from 10 grams of kernels was almost colorless
and very mobile. I consider that these are remarkably fine seeds.

I was pleased to get the reference to Memorias do Instituto,
Oswaldo Crux, etc., but I have not had an opportunity to examine it;
however, I hope to do so before long.

I was very much interested to learn that a Taraktogenus
karzii tree blossoms when only four years old, as I had previously
understood from what I had read that many years were required before
this stage was reached. It would appear that your tree No. 2, on
account of blossoming later than tree No. I," is another species
but on the other hand, as Doctor Kuhlmann states, the species
0. brasiliensis is exceedingly variable in its characteristics,
it may be only another type of the latter.

S( From all that I have learned so far, it appears that the
S, Oarpotroche oil is far superior in all respects to that of T.kurzii.
S As soon as I get additional information regarding the oil from
i your Carpotroche seeds, I shall write and let you know the results.

Thanking you very much for all of the information in your
letter, I remain

Very truly yours,

G. 5. Jamieson,
Senior Chemist in Charge,

Dr. P. H. Rolfs, '^
Consultor Technico de Agricultura do Estado de Minas Geraes,
Viscosa, Minas Geraes, Brazil.

Deear Dr. Rolfs:

I was pleased to receive your letter of April 21,193. As
suggested, I have arranged with the office of Foreign Plant Intro-
duction to plant carpotroche seed in southern Florida, the Hawaiian
Islands and the Canal Zone. They appear to be much interested in
attempting to grow these plants, and I think their suggestion to
plant them in widely different regions is good, as one locality may
be much more favorable than another both in regard to climatic and
soil conditions. I was able to give them 135 seeds for these pro-
posed experiments.

You refer to the Memoirs do Instituto Oswaldo Cruz as contain-
ing the names of the Brazilian chemists working on carpotroche seed
and oil and the interesting list of seeds that contain this oil,
but you failed to include the volume and number of this reference.
Consequently, I shall wait until I get it before attempting to locate
this article, which I am naturally very anxious to see.

I planted several of the seeds some weeks ago in flower pots
at my home and when cool weather comes I can take them inside. I
am glad to learn something about the period of time required for germi-

When the seeds from the No.2 tree arrive we shall be pleased to
make an examination of the oil.

With best regards, I remain

Very truly yours,

G. IJJamleson,
Chemist in Charge,
0il, Fat and Wax Laboratory.

Mr. P. H. Rolfs,
Escola Superior de Agricultura e Veterinaria
de Minas Geraes,
Vigosa, Brazil.

Dear Mr. Rolfs :

The Bureau of Chemistry has again become interested in chaulmoogra
oil, and in this connection their attention has been called by the American
Medical Association to Carpotroche brasiliensis. They would like to obtain
about 500 co. of the oil, or sufficient seed from which this quantity of
oil could be expressed. Would it be possible for you to supply this material?
The seed which you brought up some months ago has been planted at Chapman
Field, we have no report as yet as to whether it germinated or not. If
sufficient seed is available we shall, of course, be glad to make addition-
a! plantings of the tree.

Any assistance you may be able to give us in this connection will
be greatly appreciated.

Yours very truly,

(ohn A. Stevenson,
Botanist in Charge of Agricultural Explorations.
