Picrasane quassinoids from Picrasma javanica

Three new picrasane quassinoids were isolated from the bark of Picrasma javanica. Their structures were established using spectroscopic data and X-ray analysis. The absolute stereochemistry of their structure was determined by a modified form of Mosher's method and CD spectra.
