作者采用多形核细胞(PMNs)技术,从黄荆Vi-tex negundo种子中分离得到2个具有免疫增强活性的化合物,其中1个为木脂素(1),另1个是甾类糖苷(2)。黄荆种子用己烷脱脂,残渣再用甲醇彻底提取,甲醇提取物在填充有氯仿的硅胶柱上进行色谱分离,将以氯仿-甲醇(98∶2)洗脱的部位浓缩,浓缩 Using polymorphonuclear cell (PMNs) technology, the authors isolated two compounds with immunopotentiating activity from Vitex negundo seeds. One of them was lignan (1), and the other was terpenoid glycoside ( 2). Jatropha seeds were defatted with hexane and the residue was further extracted with methanol. The methanol extract was chromatographed on a silica gel column packed with chloroform, and the fraction eluted with chloroform-methanol (98:2) was concentrated and concentrated.
