摘要: 采用硅胶柱色谱、SephadexLH-20和制备HPLC等手段从中药三棱中分离得到一个无定形粉末状样品,根据波谱技术鉴定其结构为β-D-(1-O-乙酰基-3-O-顺-阿魏酰基)呋喃果糖基α-D-2’,4’,6’-O-三乙酰基吡喃葡萄糖苷(1)和β-D-(1-O-乙酰基-3-O-反-阿魏酰基)呋喃果糖基α-D-2’,4’,6’-O-三乙酰基吡喃葡萄糖苷(2)两个同分异构体组分1:4的混合物,此外,还分离鉴定了1个甘油酯类化合物即1-O-阿魏酰基-3-O-p-香豆酰基甘油(3),其中化合物1为未见文献报道的新化合物。

Abstract: A colourless amorphous solid was obtained by silica gel column chromatography, sephadex LH-20 and PHPLC from the rhizomes of Sparganium stoloniferum. The results of spectroscopic analysis showed that the sample was the mixture of two cis-trans isomers: β-D-(1-O-acetyl-3-O-cis-feruloyl)fructofuranosyl α-D-2',4',6'-O-triacetylglucopyranoside (1) and β-D-(1-O-acetyl-3-O-trans-feruloyl)fructofuranosyl α-D-2', 4', 6'-O-triacetylglucopyranoside (2) at the ratio of 1:4. In addition, one phenylpropanoid glycerol, i.e. 1-O-feruloyl-3-O-p-coumaroylglycerol (3) was also isolated from this plant. Among them, compound 1 is a new sucrose esters.
