Dammarane derivatives from the dried fruits of Forsythia suspensa.
Anti-inflammatory activity guided fractionation of the n-hexane soluble fraction of a 70% aqueous methanolic extract of the dried fruits of Forsythia suspensa afforded two new triterpenes. The structures of these compounds were elucidated as 3beta-acetyl-20,25-epoxydammarane-24alpha-ol (1) and 3beta-acetyl-20,25-epoxydammarane-24beta-ol (2) on the basis of spectral data interpretation as well as by comparison with those of structurally similar compounds.
