Abstract:
Object To study the chemical constituents from Epimeredi indica and search for the natu-ral compounds with bioactivities. Methods Three compounds were isolated by a combination of RP-18and silica gel column chromatographies, and their structures were identified by spectral methods. ResultsA novel 2- (3-methoxy-4-hydroxy) phenyl-ethanol 1-O-a-L- [(1→3 )-rhamnopyranosyl- 6-feruloyl] gluco-side ( I ) along with known 2-(3, 4-dihydroxy) phenyl ethanol 1-O-?-L-[(1→3)-rhamnopyranoside-4-O-caffeoyl-] glucoside (verbascoside) ( Ⅱ ), and 2-(3, 4-dihydroxy) phenyl ethanol (1→1) (2→2)-[(1→3)-rhamnopyranoside-4-O-caffeoyl glucoside (oraposide) (Ⅲ) were isolated from E. indica. ConclusionCompound I is a new compound named as epimeredinoside A and compounds Ⅱ and Ⅲ are isolated fromthis plant for the first time.
