【摘要】 采用硅胶柱层析和Sephadex LH-20凝胶柱层析从牵牛子70%(体积分数)乙醇提取物的乙酸乙酯萃取物中分离得到8个化合物,经理化及光谱方法鉴定分别为肉桂酸(Ⅰ)、阿魏酸(Ⅱ)、绿原酸(Ⅲ)、氯原酸甲酯(Ⅳ)、氯原酸丙酯(Ⅴ)、大黄酸(Ⅵ)、12-羟基松香酸甲酯(Ⅶ)、12-羟基氢化松香酸甲酯(Ⅷ)。经检索,这些化合物均为首次从牵牛属植物中分离得到。更多还原

【Abstract】 The active constituents in semen pharbitidis were studied.Seperation and purification were performed on columns of silica gel and Sephadex LH-20,and the chemical structures were elucidated by various spectroscopic data.Eight compounds were isolated from ethyl acetate fraction of 70 %(volume fraction) ethanol extract,and identified as cinnamic acid(Ⅰ),ferulic acid(Ⅱ),chlorogenic acid(Ⅲ),methyl chloroformate(Ⅳ),propyl chloroformate(Ⅴ),rhein(Ⅵ),12-hydroxy-methyl abieformate(Ⅶ) and 12-hydroxy-hydromethylabieformate(Ⅷ).These compounds were isolated from the genus Pharbitis for the first time by search.更多还原
