摘要: 本文研究萹蓄Polygonum aviculare L.乙酸乙酯萃取部位的抑菌活性和化学成分。采用打孔法进行抑菌活性实验,采用硅胶柱色谱、Sephadex LH-20凝胶柱色谱等方法进行分离和纯化,并根据理化性质、光谱数据进行结构鉴定。结果萹蓄乙酸乙酯部位对五种试验菌均显示一定的抑菌活性,并从中分离得到10个化合物,分别鉴定为没食子酸甲酯(1)、β-胡萝卜甙(2)、山柰酚(3)、槲皮素(4)、没食子酸(5)、萹蓄苷(6)、槲皮苷(7)、myricetin-3-O-(3′′-O-galloyl)-rhamnopyranoside(8)、杨梅树皮苷(9)、胡桃宁(10)。其中化合物1和8为首次从该植物中分离得到,化合物8为首次从蓼科蓼属植物中分离得到。

Abstract: To investigate the antibacterial activities and chemical constituents of Polygonum aviculare L.Silica gel and Sephadex LH-20 column chromatography was applied for isolation of the constituents and their structures were identified by means of spectroscopic and chemical data.The antibacterial experiments were studied on 5 tested strains in vitro,which showed that the ethyl acetate extraction of it had a certain antibacterial activities against tested strains.Ten compounds (1-10) were isolated and their structures were identified as following:methyl gallate(1),β-daucosterol(2),kaempferol(3),quercetin(4),gallic acid(5),avicularin(6),quercitrin(7), myricetin-3-O-(3′′-O-galloyl)-rhamnopyranoside (8),myricitrin(9) and juglanin(10).Compounds 1 and 8 are isolated from this plant for the first time.Compound 8 is isolated from the plants of Polygonaceae for the first time.

Key words: Polygonum aviculare L., Polygonaceae, methyl gallate, myricetin-3-O-(3&prime, &prime, -O-galloyl)-rhamnopyranoside
