Abstract

Objective To study the chemical constituents from the stem of Schisandra chinensis(Turcz.)Baill.Methods The compounds were isolated by column chromatography on silica gel,Al2O3 columns,together with recrystallizing methods.NMR spectral analysis was employed for the structural identification.Results Eight compounds were obtained and elucidated as(-)-schisandrin B(1),(+)-schizandrol B(2),(-)-schisandrin C(3),(+)-deoxyschizandrin(4),(+)-gomisin M1(5),(-)-dihydroguaiaretic acid(6),(-)-austrobailiguan 6(7),uracil(8).Conclusions Among these compounds,compounds 58 are obtained from the stem of Schisandra chinensis(Turcz.)Baill.for the first time.
