以阿司匹林为内标,在YWG-CN柱上用CH_3CN-(CH_3COOH-CH_3COONa-H_2O)CHCl_3(10:90:1)为流动相,用反相HPLC法测定了芍药、毛果芍药、草芍药、毛叶草芍药、川赤芍、毛赤芍、美丽芍药、窄叶芍药、块根芍药、新疆芍药、日本芍药、黄牡丹、及一种尚未定名的芍药的根中羟基芍药甙、芍药内酯甙、芍药甙和苯甲酸的含量,精密度实验CV(%)分别为2.34,3.40,2.88,3.31;回收率(%)分别为102.76(CV2.49%),99.39(CV1.03%),100.78(CV0.69%),100.93(CVL59%)。
Using aspirin as the internal standard, CH 3 CN-(CH 3 COOH-CH 3 COONa-H 2 O) CHCl 3 (10:90:1) was used as the mobile phase on the YWG-CN column, and the antibacterial drug, pilocarpine herbicide, and grasshopper drug were determined by reversed phase HPLC. Herbs such as Cinnamomum camphora, Rhizoma chuanxiong, Cinnamomum patens, Cinnamomum camphora, Narrow-leaf Cinnamomum camphora, Cinnamomum tuberculosis, Cinnamomum camphora, Cinnamomum camphora, Cinnamomum camphora, Cinnamomum camphora, and an unspecified Paeonia lactoferrin, peony lactone, peony The content of guanidine and benzoic acid, precision test CV (%) were 2.34, 3.40, 2.88, 3.31; recovery (%) were 102.76 (CV2.49%), 99.39 (CV1.03%), 100.78 (CV0) .69%), 100.93 (CVL 59%).
