摘要: 对五指毛桃的化学成分进行了研究.分离得到11个化合物,根据理化性质和波谱数据,分别鉴定为补骨脂素(Ⅰ)、伞形花内酯(Ⅱ)、 5,3',4'-三羟基-3,7-二甲氧基黄酮(Ⅲ)、 5,7,2',4'-四羟基黄酮(Ⅳ)、 5-羟基-3,7,4'-三甲氧基黄酮(Ⅴ)、山柰酚(Ⅵ)、紫云英苷(Ⅶ)、金合欢素 7-O-β-D-吡喃葡萄糖苷(Ⅷ)、木犀草素7-O-β-D-吡喃葡萄糖苷(Ⅸ)、柚皮素(Ⅹ)及胡萝卜苷(Ⅺ).经检索,化合物Ⅱ～Ⅹ为首次从该植物中分离得到,化合物Ⅲ、Ⅳ、Ⅴ、Ⅷ、Ⅸ为首次从该属植物中分离得到.

Abstract: Chemical constituents in the roots of Ficus hirta Vahl.were studied. Eleven compounds were isolated and their structures were elucidated as psoralen (Ⅰ), umbelliferon(Ⅱ), 5,3',4'-trihydroxy-3,7-dimethoxyflavone(Ⅲ), norartocarpetin(Ⅳ), 5-hydroxy-3,7,4'-trimethoxyflavone(Ⅴ), kaempferol(Ⅵ), astragalin(Ⅶ), acacetin 7-O-β-D-glucopyranoside(Ⅷ), luteolin 7-O-β-D-glucopyranoside(Ⅸ), narigenin(Ⅹ) and daucosterol(Ⅺ), respectively. Compounds Ⅱ-Ⅹ were isolated from this plant for the first time, compounds Ⅲ, Ⅳ, Ⅴ, Ⅷ, Ⅸ were obtained from the genus Ficus for the first time.
