摘要
采用HPLC法,选用Symmetry-C18柱和甲醇:水(25:75),乙酸调pH4.2。测定定晕宁颗粒中葛根素含量。结果回归方程为Y=1.77x-0.2813,r=0.999(n=5),线性范围为0.614~6.14μg,平均回收率为99.03%,RSD为3.98%。
A HPLC method has been used for the determination of puerarin content in Dingyunning Granules. It has been determined on the column RP-C18 using metholnal: water(25: 75) (adjusted to pH4. 2 using actetic acid). The detective ware was 250nm. The average recovery was 99. 03 %,RSD= 3. 98 %. The linear range was good in 0. 614~ 6.14μg/ml (r=0. 9999).
