Abstract

The bioactive ethyl acetate and N-butanol soluble parts of an ethanolic extract of Byrsocarpus coccineus leaves was subjected to column chromatography over silica gel G (60-120 microns) and repeated purification of the flavonoid rich fraction over sephadex LH-20 eluted with methanol led to the isolation of three flavonoid glycosides identified as quercetin 3-O-alpha-arabinoside (I), quercetin (II) and quercetin 3-beta-D-glucoside. Their structures were elucidated by (1)H and (13)C-NMR data and are reported here for the first time in this plant.

摘要

对绯红浆果叶乙醇提取物中的生物活性乙酸乙酯和正丁醇可溶部分进行硅胶G(60 - 120微米)柱色谱分离,并使用甲醇洗脱,通过葡聚糖凝胶LH - 20对富含黄酮类化合物的部分进行反复纯化,从而分离出三种黄酮苷,分别鉴定为槲皮素3 - O - α - 阿拉伯糖苷(I)、槲皮素(II)和槲皮素3 - β - D - 葡萄糖苷。通过¹H和¹³C - NMR数据阐明了它们的结构,且这是首次在此植物中报道这些结构。
