Abstract
The triterpene fraction (~80%) of the oleoresin from Dipterocarpus pilosus has been found to contain dipterocarpol and several known (dammara-20,24-dien-3-one, dammara-24-ene-3,20-diol, ocotillone-II, ocotillol-II) and new triterpenes related to this. Structure elucidation of two of these new triterpenes viz hollongdione and dipterocarpolic acid, is discussed. The resin also contains significant quantities of asiatic acid and two of its acetyl derivatives and 2a-hydroxyursolic acid.
