目的对短柱肖菝葜的化学成分进行研究。方法应用多种色谱技术进行分离纯化,通过理化方法和波谱数据进行结构鉴定。结果分离并鉴定了3个化合物,分别为2-O-α-L-鼠李吡喃糖基-5-C-β-D-葡萄吡喃糖基-4,6-二羟基-苯基-对羟基苯酮(Ⅰ);大豆素(Ⅱ)和β-谷甾醇酯-3β-吡喃葡萄糖苷-6′-O-棕榈酸酯(Ⅲ)。结论Ⅰ为新化合物,简易命名为肖菝葜苷B;所有化合物均系首次从该属植物中分离得到。 Objective To study the chemical constituents of the short column Xiaoxuan. Methods A variety of chromatographic techniques were used to separate and purify. Structure identification was performed by physicochemical methods and spectral data. As a result, three compounds were isolated and identified as 2-O-α-L-rhamopyridyl-5-C-β-D-glucopyranosyl-4,6-dihydroxy-phenyl-. p-Hydroxybenzophenone (I); daidzein (II) and β-sitosterol-3β-glucopyranoside-6′-O-palmitate (III). Conclusion I is a new compound, which is simply named as flavoside B; all compounds were isolated from this genus for the first time.
