【Abstract】 Objective :To establish the quantitative method of the Gastrodin in Tianma Formulation Granules by HPLC. Method :The Diamonsil C 18 Column (4.6mm×150mm 5μm) was used.The methanol-0.05% phosphoric acid (3.5∶96.5)mixture as the mobile phase,with the detection at 270nm,the flow rate was 0.9mL/min and column temperature was room temperature. Result :The liner ranges was 0.33~2.97μg( r =0.99998, n =5).The average recovery was 101.3%,RSD=1.52%( n =5). Conclusion :This method is convenient,accurate and... 更多还原 【关键词】 天麻配方颗粒; 高效液相色谱法; 天麻素; 【Key words】 Tianma Formulation Granules; HPLC; Gastrodin;
