朝鲜槐化学成分的研究

Studies on the Chemical Constituents of Amur Maackia(Maackia amurensis)

从豆科植物朝鲜槐Maackiaamurensis树皮的乙醇提取物中，分得4种结晶单体，经理化性质和光谱分析，分别鉴定为β-谷甾醇（Ⅰ），鸢尾种甙元（tectorigenin，Ⅱ），kakkatin（Ⅲ）和鸢尾种甙（tectoridin，Ⅳ）。这4个化合物均系首次从该植物中分得。

Maackia amurensis Ru, r. et Maxim is a deciduous tree of Leguminosae family distribed mainly in Eastern Asia,including Northeastern,Hebai,Neimeggu and Shandong Provinces of China. Its bark has been prescribed as a folk medicine for the treatment of rheumatism,inflammation,ache,gastric disease and bleeding by civilians of the korean nationality. Low polar and polar constituents were isolated from its bark using solvent extraction and silica gel column chromatography. The structrues of four compounds obtained were identified as β-sitosterol (Ⅰ), tectorigenin (Ⅱ), kakkatin (Ⅲ)and tectoridin (Ⅳ)by physical and chemical properties and spectrographic analysis. All four were isolated from this plant for the first time
