摘要
目的 建立蜂胶片含量测定方法。方法 以Spherigel ODS C18(250mm×4.6mm,5μm)色谱柱分离槲皮素,流动相:甲醇-16.7%四氢呋喃的0.4%磷酸溶液(38:62),检测波长:370nm。结果 线性范围:0.098~0.488μg,r=0.9999(n=5)。平均回收率97.57%,RSD=1.32%。结论 方法专属、灵敏、重现性好,为该制剂的质量控制提供依据。
Objective To establish on RP-HPLC method for the determination of quercetin in Fengjiao tablets. Methods Quercetin was separated on Spherigel ODS C18 column(250 mm×4.6 mm, 5 μm) and than determined at wavelength 370 nm, using rinse fluid of methanol-16. 7% tetahydrofuran of 0. 4% phosphoric acid solution (38 : 62) as mobile phase. Results The standard curves of quercetin were linear in the range of 0.098 0~0.488 0μg. The average recovery of quercetin was 97. 57%( RSD=1. 32%). Conclusions The method was specific and sensitive with good reproducibility,it provided a valuation for quality control of the preparation.
