Two new lignans from Schisandra henryi.
Two new lignans, henricines A (1) and B (2), were isolated along with the eight known lignans, ganshisandrine (3), wulignan A(2) (4), epiwulignan A(1) (5), deoxyschisandrin (6), wulignan A(1) (7), epischisandrone (8), schisantherin A (9), and schisandrol A (10), from the stems of Schisandra henryi. The structures of the new compounds were elucidated based on the spectral analysis, including 1D and 2D NMR experiments.
