从无莿根及炮制品藤婆茶饼的热水提取物中,用柱层析分离得到两种黄酮类成分。经理化性质和光谱数据,分别鉴定为双氢黄酮醇类化合物蛇葡萄素(Ampelopsin)和黄酮醇化合物杨梅素(Myricetin)。此两种成分均首次从该植物中得到。
Two kinds of flavonoids were separated from the hot water extracts of non-rooted and processed rattan tea cakes by column chromatography. The managerial properties and spectral data were identified as the dihydroflavonol compound Ampelopsin and the flavonol compound Myricetin. Both of these components were first obtained from the plant.
