摘要
目的:研究珠芽蓼茎叶的化学成分。方法:采用各层析色谱法对珠芽蓼茎叶提取物进行分离纯化,根据理化常数和光谱常数进行结构鉴定。结果:从珠芽蓼茎叶中分离并鉴定了11个化合物,分别为:扁蓄苷(1)、番石榴苷(2)、槲皮素-3-O-β-D-木糖-(1→2)-α-L-鼠李糖苷(3)、异槲皮苷(4)、槲皮苷(5)、山柰酚-3-O-β-D-葡萄糖苷(6)、木犀草素-7-O-β-D-葡萄糖苷(7)、金丝桃苷(8)、绿原酸(9)、新绿原酸(10)、没食子酸(11)。结论:其中,化合物1~4、7、8为首次从该植物中分离得到。
Objective: To study the chemical constituents from the stems and leaves of Polygonum viviparum.Methods: The compounds from the stems and leaves extracts of Polygonum viviparum were isolated and purified by chromatography.The structures were identified by physiochemical properties and spectrum analysis.Results: Eleven compounds were isolated from the stems and leaves of Polygonum viviparum and identified as avicularin(1),guaijaverin(2),quercetin-3-O-β-D-xylopyranosyl-(1→2)-α-L-rhamnopyranoside(3),isoquercitrin(4),quercitrin(5),kaempferol-3-O-β-D-glucoside(6),luteolin-7-O-β-D-glucoside(7),hyperoside(8),chlorogenic acid(9),neochlorogenic acid(10),gallic acid(11),respectively.Conclusion: Among them, compounds 1 to 4,7,8 are isolated from the stems and leaves of Polygonum viviparum for the first time.
