Abstract
Two kinds of known ellagic acid derivatives, 3,3'',4-tri-O-methylellagic acid and 3-O-methylellagic acid, were isolated from the leaves of L. subcostata Koehne, and from the leaves of L. speciosa (L.) Pers, respectively. From the latter, 3,4-di-O-methylellagic acid, previously reported as the aglycon of lagertannin, was synthesized. In addition to 3,3'',4-tri-O-methylellagic acid, .beta.-sitosterol, campesterol and stigmasterol were identified by gas chromatography from the leaves of L. subcostata.Keywords
