NEOLIGNANS FROM PIPER KADSURA
摘要:
Two new neolignans, Kadsuranin G and Kadsuranin H, were isolated from Piper Kadsura (Choisy) Ohwj. Baaed on the spectroscopic analysis (UV, IR, MS, NNR, and X-ray) and chemical reactions, their structures were established as 7R, BR, 1'S, 2'R, 3'5-△8'-3, 4, 5'-trimethoxy-2'-hydroxy-1', 2', 3', 4'-tetrahydro-4'-oxo-7, 3', 8, 1'-neolignan and 7R, 8R, 1'S, 2'R, 3'S-△8'-3, 4, 5'-trimethoxy-2'-acetyloxy-1', 2', 3', 4'-tetrahydro-4'-oxo-7, 3', 8, 1'-neolignan.
