摘    要:目的:研究聚酰胺富集甘草中黄酮的工艺参数,同时建立其含量测定方法。方法:以二氢黄酮类化合物在碱性条件下转化为查尔酮类的量作为指标,以柚皮苷为对照品,经聚酰胺吸附柱富集后,采用碱性比色法显色、测定。结果:纯化工艺条件为甘草聚酰胺比2∶1(g/g),树脂径高比1∶7,用5倍量柱体积70乙醇洗脱,甘草黄酮洗脱率在90左右;含量测定平均加样回收率为98.81(RSD=2.00)。总固物中黄酮含量可达45。结论:本法富集、纯化甘草总黄酮可行;甘草黄酮含量测定方法稳定,可靠。

关 键 词:甘草  黄酮  含量测定  聚酰胺

Abstract:AIM:To investigate the process parameters of adsorbing and separating the total flavones of Radix et Rhizoma glycyrrhiae and its assay. METHODS: Chalcone that flavanone in Licorice root was converted into in alkaline condition was adopted as index and niaringoside as control,through polyamide treatment,alkaline colorimetty was used to determine chalcone content. RESULTS: Under the condtion,namely, ratio of quantity of Licorice root to polyamide was 2:1,ratio of column diameter to column heighth was 1:7,70%ethanol used to eluate,flavone extract was up to 45%with 90%eluting yield.The recoveny of assaying was 98.17%(RSD=2.00%). CONCLUSION: The purification and assay of Licorice flavonoids are reliable and efficacious.
Keywords:Glycyrrhiza  flavone  polyamide
