Isolation and identification of chemical constituents from stems and leaves of Acanthopanax senticosus (Rupr.et Maxim.) Harms

Objective To study the chemical constituents of the stems and leaves of Acanthopanax senticosus(Rupr.et Maxim.)Harms.Methods The compounds were isolated by chromatography on silica gel column and identified by physical-chemical properties and spectral analysis.Results Seven compounds were obtained and identified as syrigin(1),eleutheroside B1(2),eleutheroside D(3),mannitol(4),syringaldehyde(5),2,6-dimethoxybenzoic acid phenylmethyl ester(6),salvadoraside(7).Conclusions Compounds 57 are isolated from this genus for the first time.
