Abstract: The resin of Dipterocarpus tubinatus Gaertn. f. native to the south of Yunnan (China) have been investigated. From which, six triterpenes--hydroxydammarenone-II (1), dammarenediol-II (2), betulonic acid(3), asiatic acid(4), 3,23-o-isopropylidene asiatic acid(5) and madasiatic acid (6) were isolated and established by means of spectral methods. Madasiatic acid was first isolated from the resin in Dipterocarpaceae.

Key words: Dipterocarpus tubinatus
