PROPOSED MODIFICATION OF YLANG-YLANG OIL STANDARDS ' 



By H. D. GiBBS 



(From the Laboratory of Organic Chemistry, Bureau of Science, 



Manila, P. I.) 



The ylang-ylang (Canagium odoratum BailL), a medium-sized 

 to rather large tree, is a native of the Malay Archipelago and 

 has been introduced into many other tropical countries for 

 commercial and ornamental purposes. 



The essential oil is obtained from the flowers in the Philippine 

 Islands, Indo-China, Java, Siam, New Caledonia, Jamaica, Ger- 

 man East Africa, and a number of islands in the vicinity of 

 the last country: namely, Madagascar, Mayotte, Nassi-Be, and 

 Reunion. The greatest commercial success has been attained 

 in the Philippines and in Reunion on account of the high quality 

 of the product. France takes the largest part of the oil produced 

 in these two places. 



The exports for the last five years from the Philippine Islands 

 are given in Table I.
