Quality control for compound cordycepic polysaccharide buccal tablets
-
摘要: 目的: 制定复方虫草多糖含片(北冬虫夏草多糖提取物,罗汉果提取物,西洋参提取物,茶多酚)的质量控制方法。 方法: 对罗汉果,西洋参进行薄层鉴别;茶多酚进行显色鉴别;采用苯酚-硫酸法测定复方虫草多糖含片中虫草多糖的含量。 结果: 通过方法学考察,虫草多糖浓度范围内线性关系良好,相关系数0.9964;平均回收率为97.13%RSD=1.41%(n=5)。 结论: 方法简便、准确、重现性高,可用于控制复方虫草含片的质量。Abstract: Objective: To establish a quality control method for compound cordycepic polysaccharide buccal tablets(cordycepic polysaccharide,extract of Grosvenor momordica fruit,Panax quinquefolium extract,and tea polyphenols). Methods: The extract of Grosvenor momordica and Panax quinquefolium L.were identified by TLC.Tea polyphenols was identified according to the principle of display reaction between tea catechins and vanillin.Cordycepic polysaccharide was determined by spectrophotometry method. Results: The methodological study showed that the calibration curve of polysaccharide was linear in the concentration range(r=0.996 4).The average recovery was 97.13% with the RSD of 1.41%(n=5). Conclusion: The method is simplea,ccurate,repeatilde with and high precision.This method can be used for quality control for compound cordycepic polysaccharide buccal tablets.
