196 PHILIPPINE RESINS, GUMS, AND OILS 
COMPOSITION OF ILANG-ILANG OIL 
Parry states that investigations of ilang-ilang oil have shown 
that it contains esters of benzoic and acetic acids, also linalodl, 
cadinene, pinene, P-cresol methy] ether, geraniol, and iso-eugenol. 
Parry is of the opinion that in addition to these substances, 
ilang-ilang contains other compounds, as a synthetic oil closely 
resembling the natural oil has been prepared commercially. 
Probably a considerable amount of research has been done on 
ilang-ilang, but for trade reasons the investigators do not care 
to publish their results. 
Bacon * performed a number of experiments to determine the 
composition of ilang-ilang oil and concluded that it contained * 
formic, acetic, valerianic (?), benzoic, and salicylic acids, all 
as esters; methyl] and benzyl alcohols; pinene and other terpenes, 
linalodl, geraniol, safrol, cadinene and other sesquiterpenes; 
eugenol, iso-eugenol, p-cresol, probably as methyl ethers; and 
eresol. He then prepared a synthetic oil in order to test the 
accuracy of his studies on the composition of ilang-ilang oil. 
His synthetic ilang-ilang contained the following substances 
(proportions not stated): methyl benzoate; benzyl acetate and 
formate; benzyl methyl ether (trace); benzyl valerianate 
(trace) ; methyl salicylate; benzyl benzoate; cadinene; safrol; 
iso-eugenol-methyl ether; eugenol; cresol; methyl anthranilate 
(trace) ; p-cresol-methyl ether; p-cresol acetate. This mixture‘ 
gave an odor very similar to good ilang-ilang oil. From the 
results of his own work and that of others Bacon concluded: 
* * ¥* ylang-ylang oil has a composite odor, derived from that of 
many constituents. While it is possible to make a very good artificial 
ylang-ylang oil, I do not believe that distillers of the best quality of ylang- 
ylang oil have much to fear from this competition, as the odor of a first-e 
class oil seems to have more permanence than that of the artificial product. 
This is a result, I believe, of the presence of sesquiterpene alcohols and 
fragrant resins in the former. 
GROWTH OF CANANGIUM ODORATUM 
This species has been grown in plantations at Los Banos. 
Only one lot of seeds was planted, and this showed a very low 
percentage of germination, 3.2 per cent. It is uncertain as to 
whether or not this low percentage was due to poor seed. The 
trees have done well in plantations. The average rates of growth 
of considerable numbers are given in Table 34.
