摘 要 ：从云南匙羹藤(Gymnema yunnanense Tsiang)中分离得到2个新C21甾体甙，命名为云南匙羹藤甙A(I)和B(II)(gymnemaroside A，B)。据化学反应和光谱数据，推定其结构分别为：本波甙元3-氧-β-D-葡萄糖吡喃基-(1→4)－3-氧-甲基-6-去氧-β-D阿洛糖吡喃基-(1→4)-β-D-加拿大麻糖吡喃基-(1→4)-β-D-加拿大麻糖吡喃甙[penupogenin 3-O-β-D-glucopyranosyl-(1→4)-3-O－methyl-6-deoxy-β-D－allopyranosyl-(1→4)-β-D－cymaropyranosyl-(1→4)一β-D-cymaropyranoside]和吉马甙元3-氧-β-D-葡萄糖吡喃基-(1→4）3-氧-甲基-6-去氧-β-D-阿洛糖吡喃基-(1→4) -β-D-加拿大麻糖吡喃基-(1→4) -β-D-加拿大麻糖吡喃甙[gymnemarsgenin 3－O-β-D－glucopyranosyl-(l→4)-3－O－methyl-6-deoxy-β-D－allopyranosyl-(1→4) -β-D-cymaropyranosyl-(1→4)β－D－cy－maropyranoside]。

Abstract:From the whole plant of Gymnema yunnanense Tsiang, two new Czi steroidal glycosides named gymnemaroside A(I) and B(II) were isolated. On the basis of che-mical and spectral evidence, their structures were elucidated as penupogenin 3-O-β-D-glucopyranosyl- (1 -4 )- 3 -O-methyl- 6 -deoxy-β-D-allopyranosyl- (1-4) -β-D-cymaropyranosyl-( 1-4 )-β-D-cymaropyranoside and gymnemarsgenin 3-O-β-D-gluco -pyranosyl-( 1-4 )-3-O-methyl-6-deoxy-β-D-allopyranosyl-( 1-4)-β-D-cymaropyran -osyl-( 1-4 )-β-D-cymaropyranoside, respectively.
