前曾报道辣木 Moringa oleifera 叶的降压成分,作者继续报道辣木荚果的生物活性及其化学成分。新鲜的辣木荚果用乙醇室温提取,挥去溶剂得含降压活性成分的稠状物(MO)。MO在水和乙酸乙酯中分配。含活性物质的乙酸乙酯相经一系列不同溶剂的分配萃取和柱层析,得到β-谷甾醇、O-[2′-羟基-3′-(2″-庚烯
Previously, the antihypertensive components of Moringa oleifera leaves were reported. The authors continue to report on the biological activity and chemical composition of Moringa oleifera. The fresh Moringa pods were extracted with ethanol at room temperature and the solvent was evaporated to give a thickened material (MO) containing antihypertensive active ingredients. MO was partitioned between water and ethyl acetate. The ethyl acetate phase containing the active substance is extracted with a series of different solvents and subjected to column chromatography to obtain β-sitosterol, O-[2′-hydroxy-3′-(2′′-heptene)
