长缘厚朴中的新配糖体

A New Glycoside from Magnolia rostrata

从长缘厚朴 (MagnoliarostrataW .W .Smith)干燥树皮的乙醇提取物中分离得到一个新的配糖体 ,1,1′ 联苯 6′ ,8′ ,9′ 三羟基 3 烯丙基 4 O β D吡喃葡萄糖苷 (1) ,以及 6个已知的苯丙素类配糖体 ,3,4 二羟基 -烯丙基 3 O α L 吡喃鼠李糖 (1→ 6 ) β D 吡喃葡萄糖苷 (2 ) ,3,4 二羟基 -烯丙基苯 3 O α L 吡鼠李糖 (1→ 2 ) β D 吡喃葡萄糖苷 (3) ,sina paldehyde (E) O β D glucopyranoside (4) ,syringaresinol di O β D glucopynanoside (5 ) ,A阿克苷(E) (6 ) ,IcarisideE5 (7) ,经光谱和化学方法鉴定其结构。

A new glycoside,1,1′-dibenzene-6′,8′,9′-trihydroxy-3-allyl-4-O-β-D-glucopyranoside(1) and six known glycosides,3,4-dihydroxy-alllylbenzene-3-O-α-L-rhamnopyranosyl(1→6) β-D-glucopyranoside (2),3,4-dihydroxy-alllylbenzene-3-O-α-L-rhamnopyranosyl(1→2) β-D-glucopyranoside (3),sinapaldehyde(E)-O-β-D-glucopyranoside (4),syringaresinol-di-O-β-D-glucopynanoside (5),acteoside(E) (6) and icarisideE 5 (7),were isolated firstly from the barks of the -Magnolia rostrata.Their structures were elucidated on the basis of spectral data and chemical method.
