摘  要:该文用硅胶,ODS,MCI柱色谱和半制备型HPLC等方法对青阳参的氯仿萃取中含有的C21甾体类成分进行了系统的分离纯化研究,并结合波谱数据对该类成分进行了结构确认。从青阳参氯仿萃取物分离到11个C21甾体类化合物,分别为青阳参苷乙(1),告达亭-3-O-β-D-加拿大麻吡喃糖基-(1→4)-β-D-夹竹桃吡喃糖基-(1→4)-β-D-加拿大麻吡喃糖基-(1→4)-β-D-加拿大麻吡喃糖苷(2),告达亭-3-O-β-D-夹竹桃吡喃糖基-(1→4)-β-D-夹竹桃吡喃糖基-(1→4)-β-D-加拿大麻吡喃糖基-(1→4)-β-D-加拿大麻吡喃糖苷(3),告达亭-3-O-β-D-夹竹桃吡喃糖基-(1→4)-β-D-毛地黄毒吡喃糖基-(1→4)-β-D-加拿大麻吡喃糖苷(4),青阳参苷O(5),加加明-3-O-β-D-夹竹桃吡喃糖基-(1→4)-β-D-加拿大麻吡喃糖基-(1→4)-β-D-加拿大麻吡喃糖苷(6),sinomarinoside B(7),mucronatosides C(8),wallicoside J(9),stephanoside H(10),青阳参苷元-3-O-β-D-夹竹桃吡喃糖基-(1→4)-β-D-加拿大麻吡喃糖基-(1→4)-β-D-毛地黄毒吡喃糖苷(11)。除化合物1,4和5外其他成分均为首次从该植物中分离得到的C21甾体类化合物。Eleven Cn steroids were isolated from chloroform extract of roots of Cynanchum otophylh^mby silica gel, MCI, ODS columns, and semi-preparative HPLC. Their structures were determined by spectroscopic data analysis as otophylloside B (1), cauda- tin--3-O-β-D-ymaropyranosyl-(1→4)-β-D-eandropyranosy-(1→4)-β-D-ymaropyranosyl-(1→4)-β-D-cymaropyranoside(2), cau- datin-3-O-β-D-oleandropyranosyl-(1→4)-β-D-oleandropyranosyl-(1→4)-β-D-cymaropyranosyl-( 1 --+4 ) -/3-D-cymaropyranoside ( 3 ), caudatin-3-O-/3-D-oleandropyranosyl-(1→4)-β-D-digitoxopyranosyl-(1→4)-β-D-cymaropyranoside ( 4 ), otophylloside 0 ( 5 ), gagamine-3-O-β-D-oleandropyranosyl-(1→4)-β-D-cymaropyranosyl-(1→4)-β-D-cymaropyranoside ( 6 ), sinomarinoside B ( 7 ), mucr- onatosides C ( 8 ), wallicoside J ( 9 ), stephanoside H ( 10 ), and qinyangshengenin-3-O-β-D-oleandropyranosyl-(1→4)-β-D-cymaropyr- anosyl-(1→4)-β-D-digitoxopyranoside (11). Among them, compounds 2-3, and 6-11 were separated from the roots of this plant for the first time.
