摘要
目的建立辣蓼中没食子酸的含量测定方法。方法采用A g ilentHypersilODS柱(4.0×250mm,5μm);以甲醇-水-冰醋酸为流动相;检测波长:274nm。结果没食子酸的平均回收率为100.7%,RSD为1.0%(n=6)。结论方法简便、快速、准确,可用于辣蓼的质量控制。
OBJECTIVE To establish the determination of gallic acid in Polygomum flaccidum Meisn. METHODS A agilent hypersil ODS column was used as the analytical column and methanol-water-acetic acid glacial as the mobile phase. The detection wavelength was at 274nm. RESULTS The average recoveries were 100. 7% （RSD= 1.0%, n = 6）. CONCLUSION The method is simple, accurate, sensitive and can be used to determine gallic acid in Polygonum flaccidum Meisn.
