Constituents of dipterocarpaceae resins. Part I. Triterpene acids of Dryobalanops aromatica
Seven pentacyclic triterpenes were isolated from Dryobalanops aromatica, of which two were artifacts. The structure and stereochemistry at ring A of alphitolic acid was confirmed by a partial synthesis of methyl dihydroalphitolate from betulic acid, which was obtained from Eurya acuminata.
