On the basis of physical and chemical data,IR,UV,MS, 1HNMR, 13C NMR spectra, they are identified as deoxypodophyllotoxin(DT-Ⅰ),podophyllotoxin(DT-Ⅱ), isopicropodo- phyllone(DT-Ⅲ),dehydropodophyllotoxin(DT-Ⅳ),β-peltatin(DT-Ⅴ),diphyllin(DT-Ⅵ), picropodophyllin(DT-Ⅶ),podophyllotoxone(DT-Ⅷ),4’-demethypodophyllotoxin(DT-Ⅸ), kaempferol. Podophyllotoxin yields 1 5%.展开更多

Fifteen alkaloids were isolated from the water soluble alkaloids. On the basis of physical and chemical data,IR,UV,MS, 1HNMR, 13C NMR spectra, seven of they are identified as (-)-5α-hydroxysophocarpine(LK-1),camoensine(LK-2),3α-hydroxylupanine(LK-3),13α-hydroxylupanine(LK-4),caulophylline(LK-5),(-)-7,11-dehydromatrine(LK-6),3β-hydroxylupanine(LK-7).展开更多
