摘要: 目的:研究金樱子Rosa laevigataMichx.果实的化学成分。方法:运用正反相硅胶,凝胶(Sephadex LH-20)等多种柱色谱进行分离纯化,根据理化性质和波谱数据进行结构鉴定。结果:分离得到5个化合物,经鉴定分别为2α,3β,19α-三羟基齐墩果酸(Ⅰ),山奈酚(Ⅱ),翻白叶苷A(Ⅲ),β-谷甾醇(Ⅳ),胡萝卜苷(Ⅴ)。结论:化合物Ⅰ为首次从金樱子果实中分离得到。Abstract: Objective :To investigate the chemical constituents from fruits of Rosa laevigata Michx fruits. Methods :Multi-chromatographic methods including Silica gel column chromatography and Sephadex LH-20 gel permeation were employed for the isolation and purification.The structures were identified on the basis of chemical evidence and spectral data. Results :Five compounds were isolated and identified as:2α,3β,19α-trihydroxyolean-12-en-28-oic acid(Ⅰ),kaempferol(Ⅱ),potengriffioside A(Ⅲ),β-sitosterol(Ⅳ),daucosterol(Ⅴ).Conclusions:Compound Ⅰ was isolated from fruits of Rosa laevigata Michx for the first time.
