【Abstract】 Paeoniflorins extracted by infusing, boiling and ultrasonic procedures from Sedative honey pill No. 2 and Radix Paeoniae Rubra were chromatographed on a C18 colunin with a mobile phase consisting of a mixture of methyl alcohol and 0. 05mol potassium dihydric phosphate (35 : 65 , pH3. 60) at a flow rate of 0. 8 ml/min , and detected by UV at 240nm. The linearity was excellent (r=0. 9998 ) within the range of 2～40 μg/ml of paeoniflorin. The intra-and inter-day coefficients of variation were 2. 25/00 (n= 6) and 2. 46 % (n = 6 ) respectively. The retention time(tR ) for paeoniflorin was 6.10 min under these conditions. Sample injection occurred every 12min. This method is simple, accurate and reproducible, and suitable for the quality control of honey pills as Sedative Honey Pill No. 2 and of Radix Paeoniae Rubra.更多还原
