【摘要】 从地构叶(Speranskia tuberculata)地上部分分离得到9个化合物,根据其理化性质及波谱特征被鉴定为软脂酸、β-谷甾醇、三十烷醇、香草酸、阿魏酸、对香豆酸、loliolide,胸腺嘧啶和尿嘧啶。香草酸和阿魏酸有较好的抗氧化活性,以上化合物均为首次从该植物获得。更多还原

【Abstract】 9 compounds were isolated from speranskui tuberculata. On the basis of the properties and spectral analysis their structures were identified as palmitic acid . β-sitosterol ,triacont.yl alcohol .vanillic acid,ferulic acid ,loliolide,p-coumatic acid,thymine and uracil. All the compounds were separated from the plant for the first time.Vanillic acid and ferulic acid showed the good antioxydation activities.更多还原
