车前子中多糖含量的测定

采用蒽酮-硫酸法比色测定，用精制车前子多糖测得车前子多糖对葡萄糖的换算因子，对我国同属不同品种的车前子不同采集时间及炮制前后其多糖含量进行了比较研究。结果表明：此测定方法简便可行。供试液在8h内显色稳定，重现性较好，平均回收率为97．8％，RSD=1．41％(n=5)。江西吉安产大粒车前子生品多糖含量在9．15％～9．83％之间，炮制后其多糖含量在6．29％～6.81％之间；南昌新祺周车前GAP标准基地的大粒车前子生品多糖含量为7.85％～8．38％，炮制后其多糖含量为6．01％～6．64％；东北产的小粒车前子生品多糖含量为6．61％，炮制后其多糖含量为6．45％。     

Influence of Mobile Phase Composition on the Enantioseparation of Meythoxyl Flavanones with Self—prepared CDMPC Column and Chiral Recogniton Mechanism

The influence of different alcohol modifiers in mobile phase on the chiral separation of 4‘‘‘‘‘‘‘‘-methoxyl flavanone,5-methoxyl flavanone and 6-methoxyl flavanone on cellulose tris(3,5-dimethylphenylcarbamate)(CDMPC)column was studied and the chiral recognition mechanism was discussed.Using hexane-tert-butanol(1.31molL^-1) as the mobile phase,those three methoxyl flavanones were excellently separated on CDMPC chiral column.
