不同产地黄芩药材中黄芩多糖、浸出物含量的研究

目的:对不同产地黄芩的糖类成分、浸出物等进行含量测定,为科学制定黄芩药材的质量标准提供依据。方法:采用蒽酮比色法测定黄芩糖类成分的含量;采用《中国药典》方法对黄芩的浸出物、灰分进行含量测定。结果:测得黄芩药材中总糖为(16.30±0.27)%~(55.14±2.41)%,水溶性浸出物为(32.42±0.60)%~(58.14±2.28)%,醇溶性浸出物为(40.54±0.59)%~(59.72±0.33)%,总灰分为(3.83±0.02)%~(9.12±0.12)%。结论:黄芩多糖、浸出物含量可作为控制黄芩药材质量的重要指标之一。

Study on contents of carbohydate components and extract of the radix scutellariae from different areas

Objective: To provide scientific data for establishing the quality standards of radix scutellariae by measuring the contents of carbohydate components and extract of radix scutellariae from different areas.Methods: Anthrone colorimety method was used to determine the contents of carbohydate components.According to the pharmacopoeia of the Peoples,Republic of China,the extract contents and ash of radix scutellariae were measured.Results:The following measurements were determined: the contents of total carbohydate of radix scutellariae was(16.30±0.27)%～(55.14±(2.41)%;)the extract of water-soluble substance was(32.42±0.60)%～(58.14±2.28)%;the extract of alcohol-soluble substance was(40.54±0.59)%～(59.72±0.33)%;the total ash substance was(2.10±0.09)%～(10.67±(0.42)%.)Conclusion: The carbohydate and extract of radix scutellariae is an important index of the quality standards of radix scutellariae.
