摘要
目的:研究广藿香Pogostemon cablin的非挥发性化学成分。方法:采用硅胶、Sephadex LH-20等柱色谱方法进行分离纯化,并根据化合物的理化性质和波谱数据鉴定其结构。结果:从广藿香醇提物中分离得到12个化合物,分别鉴定为田蓟苷(1),香叶木素-7-O-β-D-吡喃葡萄糖苷(2),1,2-O-[2S-(3,4-二羟基苯基)-1,2-乙烷二基]-3-O-α-L-鼠李吡喃糖基-4-O-阿魏酰基-β-D-吡喃葡萄糖苷(3),尿嘧啶(4),大豆脑苷Ⅰ和Ⅱ(5),藿香苷(6),7-O-(3″,6″-二-反式-对-香豆酰基)-β-D-半乳糖-芹菜素苷(7),5-羟基-3,3′,4′,7-四甲氧基黄酮(8),4′,5-二羟基-3,3′,7-三甲氧基黄酮(9),金合欢素(10),1,2-O-[2S-(3,4-二羟基苯基)-1,2-乙烷二基]-3-O-α-L-鼠李吡喃糖基-4-O-咖啡酰基-β-D-吡喃葡萄糖苷(11),1,2-O-[2S-(3,4-二羟基苯基)-1,2-乙烷二基]-3-O-α-L-鼠李吡喃糖基-6-O-咖啡酰基-β-D-吡喃葡萄糖苷(12)。结论:化合物1,2,47,10为首次从该属植物中分离得到。
Objective: To investigate the nonvolatile chemical constituents from the ethanol extract of the stems of Pogostemon cablin.Method: The constituents were isolated and purified by repeated column chromatography on silica gel and Sephadex LH-20.Their structures were identified by physicochemical properties and spectroscopic analysis.Result: Twelve compounds were isolated and identified as tilianin(1),diosmetin-7-O-β-D-glucopyranoside(2),3-O-methylcrenatoside(3),uracil(4),soya-cerebroside Ⅰ and Ⅱ(5),agastachoside(6),apigenin-7-O-(3″,6″-di-(E)-p-coumaroyl)-β-D-galactopyranoside(7),5-hydroxy-3,3′,4′,7-tetramethoxy flavone(8),4′,5-dihydroxy-3,3′,7-trimethoxyflavone(9),acacetin(10),crenatoside(11),isocrenatoside(12).Conclusion: Compounds 1,2,4-7,10 were isolated from the genus Pogostemon for the first time.
