摘要
目的:对毛泡桐果实中的化学成分进行研究。方法:应用多种色谱技术进行分离纯化,通过理化性质和波谱数据解析确定化合物的结构。结果:从毛泡桐果实中分离得到7个化合物,分别鉴定为:乌苏酸(1)、芝麻素(2)、2α,3α,19α-三羟基-12-烯-28-乌苏酸(3)、木犀草素(4)、小麦黄素-7-O-β-D-葡萄糖苷(5)、3',4',5,7-四羟基-6-[7-羟基-3,7-二甲基-2(E)-辛烯]二氢黄酮(6)、豆甾醇(7)。结论:其中,化合物3、5、7为首次从该属植物中分离得到,化合物2为首次从该植物中分离得到。
Objective: To investigate the chemical constituents from the fruits of Paulownia tomentosa. Methods: The compounds were isolated and purified by column chromatography and their structures were identified on the basis of physicochemical properties and spectral analyses. Results: Seven compounds were isolated and their structures were identified as ursolic acid( 1),sesamin( 2),2α,3α,19α-trihydroxyurs-12-en-28-oic acid( 3),luteolin( 4),tricin-7-O-β-D-glucoside( 5),3',4',5,7-tetrahydroxy-6-[7-hydroxy-3,7-dimethyl-2( E)-octenyl]flavanone( 6) and stigmasterol( 7). Conclusion: Compounds 3,5 and 7 are isolated from Paulownia genus for the first time. Compound 2 is isolated from Paulownia tomentosa for the first time.
