【摘要】 采用硅胶柱、ODS和凝胶柱色谱进行分离纯化,通过理化方法和波谱分析进行结构鉴定。从檵木(Loro-petalum chinense(R.Br.)oliver)茎叶中分离并鉴定了六个化合物:植物醇(1)、glycerol 1-(14-methlpentadecano-ate)(2)、methyl-(7R,8R)-4-hydroxy-8′,9′-dinor-4′,7-epoxy-8,3′-neolignan-7′-ate(3)、trans-p-coumaric acid ethylester(4)、落叶松树脂酸(laricinolic acid)(5)、tiliroside(6)。除化合物1外,其余化合物均为首次从檵木中分离得到,化合物2、3首次从该属中分离得到。更多还原

【Abstract】 Six compounds were isolated and purified from Loropetalum chinense(R.Br.) oliver by using silica gel,ODS,and Sephadex LH-20 column chromatography,and their structures were determined on the basis of physicochemical properties and spectroscopic analysis.They were identified as trans-phytol(1),glycerol 1-(14-methlpentadecanoate)(2),methyl-(7R,8R)-4-hydroxy-8′,9′-dinor-4′,7-epoxy-8,3′-neolignan-7′-ate(3),trans-p-coumaric acid ethyl ester(4),laricinolic acid(5),tiliroside(6).All of these compounds except 1 were isolated from this plant for the first time.Moreover,it is the first time to report 2 and 3 from the genus Loropetalum.更多还原
