番杏(Tetragonia tetragonioides)具镇静作用。作者等以番杏的抗溃疡为指标进行有效成分的分离。番杏的甲醇提取液,经甲醇、氯仿进行Folch 分配。将氯仿液所得的脂质组分进行硅胶柱层析,用氯仿-甲醇(10:1)洗脱,用硅烷化的硅胶60分离,从甲醇-水(3:1)洗脱部分得化合物A 和B_1的混合组分,再进一步分别用溶剂洗脱及硅胶分离,得化合物A 和化合物B_1。
Aging (Tetragonia tetragonioides) with a sedative effect. The author used the anti-ulcer of apricot as the index to separate the active ingredients. Aging apricot methanol extract, methanol, chloroform Folch distribution. The lipid fraction obtained from the chloroform solution was subjected to silica gel column chromatography, eluted with chloroform-methanol (10: 1) and separated on silanized silica gel 60 to give a fraction A as eluant from methanol-water (3: 1) And B_1 mixed components, and then further separated by a solvent and separated by silica gel to give a compound A and a compound B_1.
