本文的目的是对水杨柳的根部进行化学成分研究,采用硅胶柱色谱的方法分离和纯化化合物,根据理化性质和波谱方法鉴定化合物结构。从水杨柳的根部分离得到了13个化合物,包括1-羰基-油桐酸(1),油桐酸(2),3-乙酰氧基-油桐酸(3),蒲公英赛酮(4),蒲公英赛醇(5),3-乙酰氧基-12-齐墩果烯-28-酸甲酯(6),3-乙酰氧基-12-齐墩果烯-28-醇(7),熊果酸(8),羽扇豆醇(9),乙酰氧羽扇豆醇酯(10),臭矢菜素A(11),大黄酚(12)和没食子酸(13)。化合物1为新的蒲公英赛烷三萜类化合物,化合物2~12均为首次从该植物中分离得到。并用MTT法测定了化合物1~3对AGZY 83-a和SMMC-7721细胞的抑制作用。证明化合物2对AGZY 83-a细胞有弱抑制作用(IC5033.055μg.mL-1)。
The purpose of this paper is to study the chemical composition of the root of Salix miltiorrhiza. The compounds were isolated and purified by silica gel column chromatography. The structures of the compounds were identified by physicochemical properties and spectroscopic methods. Thirteen compounds were isolated from the roots of Salix miltiorrhiza, including 1-carbonyl-tungstic acid (1), eleostearic acid (2), 3-acetoxy-tungstic acid (3), and dandelion (4). , Taraxacol (5), 3-Acetoxy-12-Zoleranes-28-Methyl Ester (6), 3-Acetoxy-12-Oleobran-28-ol (7), Ursolic acid (8), Lupeol (9), Acetyloxy lupeol ester (10), Saponin A (11), Chrysophanol (12) and Gallic acid (13). Compound 1 is a new dandelione triterpenoid compound. Compounds 2 to 12 were isolated from this plant for the first time. The inhibitory effect of compound 1~3 on AGZY 83-a and SMMC-7721 cells was measured by MTT assay. Compound 2 was shown to have a weak inhibitory effect on AGZY 83-a cells (IC5033.055 μg.mL-1).
