Abstract

A study was carried out to evaluate flavonol glycosides in leaves of Symplocarpus renifolius (Araceae). From the water fraction of the MeOH extract, three new flavonol glycosides were isolated along with three known compounds, kaempferol-3-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl-7-O-b eta-D-glucopyranoside,quercetin-3-O-beta-D-glucopyranosyl-(1-->2)-beta-D -glucopyranoside, and caffeic acid. The structures of the new flavonol glycosides were elucidated by chemical and spectral analyses as quercetin-3-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl-7-O-be ta-D-glucopyranoside, isorhamnetin-3-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyra nos yl-7-O-beta-D-glucopyranoside, and quercetin-3-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl-7-O-(6 ''''-trans-caffeoyl)-beta-D-glucopyranoside.

摘要

开展了一项研究以评估细辛（天南星科）叶片中的黄酮醇苷。从甲醇提取物的水部分中，分离出三种新的黄酮醇苷以及三种已知化合物，即山柰酚-3-O-β-D-吡喃葡萄糖基-(1→2)-β-D-吡喃葡萄糖基-7-O-β-D-吡喃葡萄糖苷、槲皮素-3-O-β-D-吡喃葡萄糖基-(1→2)-β-D-吡喃葡萄糖苷和咖啡酸。通过化学和光谱分析确定新黄酮醇苷的结构为槲皮素-3-O-β-D-吡喃葡萄糖基-(1→2)-β-D-吡喃葡萄糖基-7-O-β-D-吡喃葡萄糖苷、异鼠李素-3-O-β-D-吡喃葡萄糖基-(1→2)-β-D-吡喃葡萄糖基-7-O-β-D-吡喃葡萄糖苷和槲皮素-3-O-β-D-吡喃葡萄糖基-(1→2)-β-D-吡喃葡萄糖基-7-O-(6''''-反式-咖啡酰基)-β-D-吡喃葡萄糖苷。
