摘要: 从宁夏产植物牛心朴子( Cynanchum komarovii Al. Iljinski.) 须根的乙醇提取物中分离并鉴定了4 个C21 甾体配糖体: 白前苷元C 3- O-β-D-吡喃葡萄糖基-(1→4 )-β-D-吡喃葡萄糖基-( 1→4-α-L-吡喃磁麻糖基-( 1→4 )-β- D-吡喃毛地黄毒糖基- (1→4 )-β- D-吡喃夹竹桃糖苷( 1) , 白前苷元A 3- O-β- D-吡喃葡萄糖基- (1→4 ) -β-D-吡喃葡萄糖基-(1→4 ) -α- D-吡喃夹竹桃糖基- (1→4 )-β- D-吡喃毛地黄毒糖基-(1→4 )-β- D-吡喃夹竹桃糖苷(2) , 白前苷元C 3- O-β-D-吡喃葡萄糖基-(1→4 )-β- D-吡喃葡萄糖基- (1→4 )-α- D-吡喃夹竹桃糖基-(1→4 ) -β-D-吡喃磁麻糖基-( 1→4 )-β- D-吡喃夹竹桃糖苷( 3) , 白前苷元A 3- O-β- D-吡喃葡萄糖基-(1→4 )-β-D-吡喃葡萄糖基-( 1→4 )-α- D-吡喃夹竹桃糖基- (1→4 ) -β-D-吡喃磁麻糖基- (1→4 )-β- D-吡喃夹竹桃糖苷( 4) , 分别命名为komaroside I (1) , komaroside J ( 2) , komaroside K ( 3) , komaroside L ( 4) , 除化合物1 外,其余化合物均为新化合物。

Abstract: Three new C21 steroidal glycosides : komaroside J (2) , komaroside K (3) and komaroside L (4 ) were isolated from the EtOH extract of Cynanchum komarovii Al. Iljinski., together with a known compound komaroside I (1 ). All the compounds were isolated from this plant for the first time.

Key words: Cynanchum komarovii Al. Iljinski.
