摘  要：
对高寒草原3种蓼科植物全株不同部位的酚类物质含量进行了测定和比较.结果表明:植物不同的部位的酚类物质含量不同.珠芽蓼、西伯利亚蓼和圆穗蓼酚类物质含量最高的部位分别为根、茎叶和花穗,总酚含量分别为67.18、72.41、98.12 g/kg;简单酚含量分别为31.32、34.90、30.16 g/kg;单宁含量分别为35.86、37.51、67.96g/kg;缩合单宁含量依次为26.09、36.90、31.69 g/kg.珠芽蓼与西伯利亚蓼茎叶与根中酚类物质含量高于圆穗蓼,花穗中含量反之.3种植物酚类物质的蛋白质结合能力为珠芽蓼>西伯利亚蓼>圆穗蓼.

摘  要：
The phenols contents in stems,flowers,roots of three species in the genus Polygonum in alpine meadows,including P.viviparum L.,P.sibiricum Laxm.,P.macrophyllum D.Don were determined.The results showed that the highest phenols contents of P.viviparum,P.sibiricum,P.macrophyllum existed in roots,stems and flowers,respectively.The total phenol contents were 67.18,72.41 and 98.12 g/kg,respectively.The simple phenol contents were 31.32,34.90 and 30.16 g/kg,respectively.In addition,tannin contents were 35.86,37.51 and 67.96 g/kg,respectively,condensed tannin were 26.09,36.90,31.69 g/kg,respectively.The phenols contents in stems and roots of both P.viviparum and P.sibiricum were higher than P.macrophyllum,and on the contrary,the phenols contents in flowers of P.macrophyllum was the highest.The order in aspect of protein precipitable capacity of phenols of three species was as P.viviparum>P.sibiricum>P.macrophyllum.
