摘要
目的建立湿毒清胶囊中阿魏酸的含量测定方法。方法采用HPLC法,uBondapak C18(4.0mm×250mm),甲醇-25%冰醋酸溶液(30:70)为流动相,检测波长323nm。结果阿魏酸在50~100μg·mL^-1。浓度范围内呈良好的线性关系,r=0.9999(n=5)。平均回收率100.15%,RSD为1.60%。结论该法简便、灵敏、准确。可用于湿毒清胶囊的质量控制。
OBJECTIVE To establish a method for the determination of ferulic acid in Shiduqing capsules. METHODS HPLC method was used in the quantitative analysis using a uBondapak C18 (4.0mm × 250mm)column. The mobile phase was methyl alcohol -25 % glacial acetic acid(30 : 70) and detecting wavelength was 323 nm. RESULTS The calibration curve was linear in the range of 50 - 100μg· mL^-1 for ferulic acid(r = 0.9999, n = 5). The average recovery was 100.15 % and RSD was 1.60 %. CONCLUSION This method is simple, sensitive, accurate and available for the quality control of Shiduqing capsules.
