摘要
目的:测定南方菟丝子及其不同炮制品(清炒、酒炙、盐炙)多糖的含量,从多糖变化角度探究炮制原理。方法:以南方菟丝子精制多糖测得菟丝子粗多糖对甘露糖的换算因子,以苯酚-硫酸分光光度法测定南方菟丝子及其炮制品多糖的含量。结果:菟丝子多糖精制前后单糖组成无明显变化,多糖供试液在6 h内显色稳定,重复性好,平均加样回收率为99.4%,RSD 3.02%(n=6)。测得南方菟丝子生品及不同炮制品(清炒、酒炙、盐炙)多糖含量分别为6.71%,8.27%,8.54%,14.17%,RSD分别为0.59%,2.47%,1.40%,0.35%(n=3)。结论:南方菟丝子经过炮制后多糖含量明显增加,以盐炙菟丝子含量为最高,酒炙菟丝子和炒菟丝子次之。
Objective:To determine content of polysaccharides of different processing drugs(plain-frying drugs,stir-heating drugs with wine and stir-heating drugs with salt) in Cuscuta australis.To explore the processing principle from the angel of changes of polysaccharides.Method:The conversion coefficient of C.australiss polysaccharides to mannitose was obtained by refined polysaccharides,and then the content of crude polysaccharides in C.australis and its processed products were determined by phenol-sulferic acid method.Result: Afer refining,monosaccharide composition of polysaccharides have no obvious changes.The color of solutions for testing showed good stabilization within 6 h and the average value of the recovery for polysaccharides measurement was 99.4% with 3.02% of RSD(n=6).The contents of polysaccharides and different processing drugs(plain-frying drugs,stir-heating drugs with wine and stir-heating drugs with salt) in C.australis were 6.71%,8.27%,8.54%,14.17%,with 0.59%,2.47%,1.40%,0.35% of RSD(n=3).Conclusion:The content of polysaccharides obviously increased after processed.Salt content is the highest;plain-frying and wine content took second place.
