PHILIPPINE TERPENES AND ESSENTIAL OILS, III. 127 



with cadinene liydrobromide, as we have in the PliilijjjDines a large 

 supply of this sesquiterpene obtainable from the oil of supa. 



THE DISTILLATION OF BLUMEA BALSAMIFEEA DC. 



Bluniea halsamifera DC. grows very abundantly in many parts of 

 the Philippines. I have made a few experiments for the purpose of 

 determining whether this plant can profitably be cultivated and utilized. 

 Prom 0.1 to 0.4 per cent of a yellow oil with a camphor-like odor is 

 obtained on distilling the leaves. This is almost pure Z-borneol. As 

 this substance is so easily oxidized to camphor, the oil from Blumea 

 halsamifera should be valued at from one-half to three-fourths the price 

 of camphor. The growth of this plant in the Philippines is exceedingly 

 vigorous and the leaves could be cut four times a year. According to 

 some experiments made in Indo-China/' it is possible to obtain 50,000 

 kilos of leaves per hectare, per year, which would give a possible borneol 

 yield of from 50 to 200 kilos per hectare. As labor is not exceedingly 

 cheap in the PhilijDpines, it is a question whether the cultivation and 

 distillation of these plants could he handled at a profit This would 

 need to be worked out. 



THE DISTILLATIOjST OF LANTAVNA CAJMAKA L. 



Lantavna camara L., a sweet-scented weed, is exceedingly abundant 

 in the Philippines. It grows so abundantly and so luxuriantly that if 

 the oil is of any value, its cultivation is certainly a commercial possibility. 



Seventy kilos of the leaves distilled with steam gave 60 cubic centimeters of 

 a light yellow oil; 100 kilos gave 245 cubic centimeters, and 110 kilos gave 78 

 cubic centimeters of oil. 



These results show that the yield of oil evidently varies considerably, the 

 differences depending upon the season, age of the leaves, etc. The oil has a 



specific gravity of 15! =0.9132; n52! =1.4913; A^ =-|-11.5. Its odor reminds 



me somewhat of sage. Fifty grams distilled in vacuo gave two fractions as 

 follows : 



(1)- Twenty-two grams boiling between 125° to 130° at 12 millimeters; N i^= 



1.4892. 



(2) Twenty-four grams boiling between 130° and 140° at 11 millimeters; 



N?2! =1.4970.

We shall send samples to Europe for valuation, and if it proves to be of any 



commercial value we will study the question further. 



OIL OF YLANG-YLANG. 



In a previous paper in this series,^^ I published constants on first and 

 second grade, pure ylang-ylang oils of known origin. Various regular- 

 ities were noted which justified me in stating that first grade ylang-ylang
