| 摘 要： | 从萝摩科植物华萝摩(Metaplexis hemsleyana Oliv.)的根中分离到四个新甾体去氧糖甙, 分别命名为hemoside A(1), hemosideB(2), hemoside C(3)和hemoside D(4)。经光谱分析及化学反应鉴定其结构依次为: 12, 20-O-二苯甲酰肉珊瑚苷元3-O-β-D-磁麻吡喃糖苷; 12, 20-O-二苯甲酰肉珊瑚苷元3-O-β-D-黄夹吡喃糖基(1→4)-β-D-夹竹桃吡喃糖基(1→4)-β-D-磁麻吡喃糖苷; 12-O-乙酰-20-O-苯甲酰肉珊瑚苷元3-O-β-D-黄夹吡喃糖基(1→4)-β-D-夹竹桃吡喃糖基(1→4)-β-D-磁麻吡喃糖苷; 吉马苷元3-O-β-D-黄夹吡喃糖基(1→4)-β-D-夹竹桃吡喃糖基(1→4)-β-D-磁麻吡喃糖苷。

| Abstract: | Four new compounds named hemoside A, B, C and D were isolated from the roots of Metaplexis hemsleyana Oliv. (Asclepiadaceae). Their chemical structures were determined as 12, 20-dibenzoylsarcostin 3-O-β-D-cymaropyranoside (1), 12, 20-dibenzoylsarcostin 3-O-β-D-thevetopyranosyl (1→4)-β -D-oleandropyranosyl (1→4)-β-D-cymaropyranoside (2), 12-acetyl-20-benzoylsarcostin 3-O-β-D-thevetopyranosyl (1→4)-β-D-oleandropyranosyl (1→4)-β-D-cymaropyranoside (3) and gymnemarsgenin 3-O-β-D-thevetopyranosyl (1→4)-β -D-oleandropyranosyl (1→4)-β-D-cymaropyranoside (4) respectively by means of NMR and other spectral and chemical methods. |
