To develop a method for the determination of salvianolic acid B and paeoniflorin in Shuangdan granules.
The chromatographic separation was performed on a Zorbax SB C18 column with a linear gradient elution of phosphoric acid-water (0.05:100) and phosphoric acid-acetonitrile-methanol (0.05:4:96) was used. The flow rate was 1 mL x min(-1) and column temperature was set at 25 degrees C. The UV detection wavelength was set at 230 nm.
The linear ranger was of 0.710-22.7 microg for salvianolic acid B and 0.103-3.30 microg for paeoniflorin. Three batches of Shuangdan granules were analyzed, and the content of salvianolic acid B ranged from 6.46-11.6 mg x g(-1) and paeoniflorin ranged from 1.44-1.78 mg x g(-1).
The method was accurate, reproducible, reliable, and could be used for quantitative control of Shuangdan granules.
建立双丹颗粒中丹酚酸B和芍药苷的含量测定方法。
采用Zorbax SB C18柱进行色谱分离,以磷酸-水(0.05:100)和磷酸-乙腈-甲醇(0.05:4:96)进行线性梯度洗脱。流速为1 mL·min⁻¹,柱温设定为25℃,紫外检测波长设定为230 nm。
丹酚酸B的线性范围为0.710 - 22.7 μg,芍药苷的线性范围为0.103 - 3.30 μg。对三批双丹颗粒进行分析,丹酚酸B的含量范围为6.46 - 11.6 mg·g⁻¹,芍药苷的含量范围为1.44 - 1.78 mg·g⁻¹。
该方法准确、重现性好、可靠,可用于双丹颗粒的定量控制。
