The Oleo-resin from Dipterocarpus Indicus

Abstract

In a, previous paper (K. Sitaram lyer and J. J. Sudborough this Vol. p. 29) attention has been drawn to the fact that when the oleo-resin derived from the common S. Indian tree, Hardwickia Pinnata, is stram distilled a volatile oil is obtained which contains appreciable amounts of caryophyllene. The properties of the oil are almost identical with those of Copaiba oil and the suggestion was made that the oil might be used in medicine as a substitue for Copaiba oil.
