素馨花糖苷类化学成分研究

为了研究木犀科植物素馨花干燥花蕾的化学成分，应用硅胶柱色谱、Sephadex LH-20柱色谱和重结晶等方法进行分离纯化，根据化合物的理化性质和波谱数据鉴定结构。从素馨花干燥花蕾70%乙醇提取物中分离得到7个糖苷类化合物，分别鉴定为山柰酚-3-O-α-L-吡喃鼠李糖基(1→3)-［α-L-吡喃鼠李糖基(1→6)］-β-D-吡喃半乳糖苷(I)、山柰酚-3-O-芸香糖苷(II)、7-ketologanin (III)、oleoside-11-methyl ester (IV)、7-glucosyl-11-methyl oleoside (V)、ligstroside (VI)、橄榄苦苷(VII)。化合物I为新化合物，化合物III、V为首次从本属植物中分离得到，化合物II、IV、VI为首次从本植物中分离得到。

Glycosides from flowers of Jasminum officinale L. var. grandiflorum

To study the chemical constituents of the flower of Jasminum officinale L. var. grandiflorum. The compounds were isolated and purified by re-crystallization and chromatography on silica gel and Sephadex LH-20 column. Their structures were elucidated on the physicochemical properties and spectral analysis. Seven glycosides were identified as kaempferol-3-O-alpha-L-rhamnopyranosyl (1-->3)-[alpha-L-rhamnopyranosyl (1-->6)]-beta-D-galactopyranoside (I), kaempferol-3-O-rutinoside (II), 7-ketologanin (III), oleoside-11-methyl ester (IV), 7-glucosyl-l1-methyl oleoside (V), ligstroside (VI), oleuropein (VII). Compound I is a new compound. Compounds III and V were isolated from the family of Jasminum for the first time and compounds II, IV and VI were isolated from Jasminum officinale L. var. grandiflorum for the first time.
