摘要
采用钼蓝比色法和硫酸-苯酚法测定云南不同产地何首乌药材的磷脂和总糖,结果表明:磷脂含量以寻句最高达1.85%,新平、禄劝等地在1%~1.5%,华宁、文山等地低于1%,腾冲最低为0.47%;总糖含量以新平最高达36.74%,其次为楚雄22.80%,文山、邱北14%~20%,石屏、腾冲等地在10%~14%,广南、禄劝等地低于10%。不同产地何首乌的磷脂和总糖含量差异较大,总糖和磷脂含量之间无相关性,与二苯乙烯苷等有效成分含量呈现一定程度的负相关,与何首乌的色泽呈一定相关性。
Sugar and phospholipid contents of Polygonum multiflorum sam- ple from different districts of Yunnan were determined by spectrophotometry. The maximum of phospholipid is 1.85% and the minimum 0.47% , most between0.6% ~1.5% and the maximum of sugar is 36.74% and the minimum3.65% , most between 6% ~23%. The sugar and phospholipid of the samples frnm different districts obviously varied in content. Sugar content was related with color and quality of Polygonum multiflorum.
