摘　　要：Abstract: Schisandra rubriflora Rehd. et Wils. is a traditional Chinese medicine. To search for new and bioactive components from traditional Chinese medicines and provide scientific evidence for taxonomy, the chemical constituents of the plant were investigated by various column chromatography methods (silica gel, Sephadex LH-20, and RP-18). From the aerial parts of S. rubriflora, three new megastigmane glycosides, namely (3S, 5R, 6S, 9R)-megastigmane-3, 9-diol 3-O-[α-L-arabionfuranosyl-(1→6)-β-D-glucopyranoside] (1), 7-megastigmene-3-ol-9-one 3-O-[α-L-arabionfuranosyl-(1→6)-β-D-glucopyranoside] (2), and megastigmane-3α, 4β, 9σ-triol 3-O-β-D-glucopyranoside (3), along with 14 known compounds, were isolated. The structures of the new compounds were elucidated by a combination of spectroscopic and chemical methods.Abstract: Schisandra rubriflora Rehd. et Wils. is a traditional Chinese medicine.
