In addition to β-sitosterol, a new tannin was separated and named "lagertannin" from the leaves of Lagerstroemia speciosa (L.) PERS. It's chemical structure was clarified as 3, 4-di-O-methyl-4'-O-β-D-glucosylellagic acid. Stigmasterol, campesterol, and five kinds of olefins were identified by gas chromatography.
