摘要: 采用HPLC法测定清蒸大黄中的5种游离蒽醌的含量。色谱柱为Thermo BDS HYPERSII C18柱(4.6 mm×250 mm,5 μm),以甲醇-0.1%磷酸(76∶24)水溶液为流动相,检测波长为254 nm,流速1.0 mL/min,柱温30 ℃,进样量10 μL。结果表明,芦荟大黄素、大黄酸、大黄素、大黄酚、大黄素甲醚分别在0.020 7~0.414 0 μg(R2=0.999 9)、0.172 1~3.442 0 μg(R2=0.999 6)、0.020 3~0.406 0 μg(R2=0.999 9)、0.148 0~2.960 0 μg(R2=0.999 8)、0.164 0~3.280 0 μg(R2=0.999 3)的线性范围内呈良好线性关系,说明该方法可作为大黄及其不同炮制品的质量控制方法。

Abstract: To determine the contents of 5 kinds of free anthraquinones in steamed rhubarb by HPLC. The column was Thermo BDS HYPERSII C18 column (4.6 mm×250 mm,5 μm), with methanol -0.1% phosphoric acid (76∶24) aqueous solution as mobile phase, detection wavelength was 254 nm, flow rate. 1.0 mL/min, column temperature 30 ℃, injection volume 10 μL. The results showed that aloe-emodin, rhein, emodin, chrysophanol and emodin methyl ether showed good linear relationship in the linear range of 0.020 7~0.414 0 μg(R2=0.999 9), 0.172 1~3.442 0 μg(R2=0.999 6), 0.020 3~0.406 0 μg(R2=0.999 9),0.148 0~2.960 0 μg(R2=0.999 8), 0.164 0~3.280 0 μg(R2=0.999 3). This method can be used as a quality control method for rhubarb and its different processed products.
