摘要

目的: 建立分别以其中任何1个结合型蒽醌为内参物均可用于测定大黄药材中8个结合型蒽醌的一测多评法(QAMS法)。方法: 采用高效液相色谱法,色谱柱为Symmetry C18(250 mm×4.6 mm,5 μm),以甲醇(A)-0.1%磷酸水(B)为流动相进行梯度洗脱,流速为1.0 mL·min-1,柱温为30 ℃,检测波长为280 nm。分别以芦荟大黄素-8-O-葡萄糖苷、大黄酸-8-O-葡萄糖苷、大黄素-1-O-葡萄糖苷、大黄酚-1-O-葡萄糖苷、大黄酚-8-O-葡萄糖苷、芦荟大黄素-3-羟甲基-O-葡萄糖苷、大黄素-8-O-葡萄糖苷、大黄素甲醚-8-O-葡萄糖苷为内参物,采用多点校正法,建立另外7个待测成分与内参物的相对校正因子(RCFs),计算待测成分与内参物色谱峰的相对保留时间(RRTs)。采用RCFs计算分别以其中1个成分为内参物时28批大黄药材中另外7个待测成分的含量,以差异百分比(PD)为参数,与外标法(ESM)测定结果进行比较,验证QAMS的准确性。结果: 分别以芦荟大黄素-8-O-葡萄糖苷、大黄酸-8-O-葡萄糖苷、大黄素-1-O-葡萄糖苷、大黄酚-1-O-葡萄糖苷、大黄酚-8-O-葡萄糖苷、芦荟大黄素-3-羟甲基-O-葡萄糖苷、大黄素-8-O-葡萄糖苷、大黄素甲醚-8-O-葡萄糖苷为内参物时,另外7个待测成分与内参物的RCFs分别为1.435、0.624、1.206、0.849、1.718、0.563、0.549,0.697、0.435、0.841、0.592、1.197、0.392、0.383,1.603、2.3、1.932、1.36、2.753、0.897、0.88,0.83、1.191、0.518、0.704、1.425、0.464、0.455,1.178、1.691、0.736、1.421、2.024、0.663、0.647,0.582、0.835、0.363、0.702、0.494、0.328、0.32,1.788、2.566、1.117、2.157、1.518、3.072、0.982和1.822、2.616、1.137、2.197、1.547、3.13、1.025,RRTs分别为1.207、1.47、1.68、1.719、1.763、1.768、2.015,0.829、1.218、1.393、1.425、1.461、1.466、1.671,0.681、0.821、1.143、1.169、1.199、1.203、1.371,0.596、0.719、0.876、1.023、1.049、1.053、1.2,0.583、0.703、0.856、0.977、1.026、1.029、1.173,0.568、0.685、0.835、0.953、0.975、1.003、1.143,0.566、0.683、0.832、0.95、0.972、0.997、1.139和0.497、0.599、0.73、0.834、0.853、0.875、0.878。8个成分含量的QAMS法计算结果的均值与ESM法测定结果之间的PD均<3%。结论: 所建立的QAMS法准确、可行,可在实际工作中只有任何1个对照品情况下同时测定大黄药材中8个结合型蒽醌的含量。

Abstract

Objective: To establish a quantitative analysis of multi-components by single marker (QAMS) method for the determination of eight anthraquinone glycosides in Rhei Radix et Rhizoma when any one of them was chosen as the internal reference substance. Methods: HPLC method was developed on a Symmetry C18 (250 mm×4.6 mm, 5 μm) column with methanol (A)-0.1% phosphoric acid (B) as mobile phase for a gradient elution. The flow rate was set at 1.0 mL·min-1, the temperature maintained at 30 ℃, and the detection wavelength was set at 280 nm. Aloe emodin-8-O-glucoside, rhein-8-O-glucoside, emodin-1-O-glucoside, chrysophanol-1-O-glucoside, chrysophanol-8-O-glucoside, aloe emodin-3-CH2-O-glucoside, emodin-8-O-glucoside, and physcion-8-O-glucoside was chosen as the internal reference substance, respectively, the relative correction factors (RCFs) of other seven components to be measured to the internal reference substances were established by multi-point correction method, and the relative retention time (RRTs) of the chromatographic peaks of components to be measured to the ones of the internal reference substances were calculated, respectively. The contents of other seven components to be measured in 28 batches of Rhei Radix et Rhizoma were calculated by RCFs when one of the eight components was used as the internal reference substance respectively, and the percentage difference (PD) was used as a parameter to compare the results with that of external standard method (ESM) to verify the accuracy of QAMS. Results: When aloe emodin-8-O-glucoside, rhein-8-O-glucoside, emodin-1-O-glucoside, chrysophanol-1-O-glucoside, chrysophanol-8-O-glucoside, aloe emodin-3-CH2-O-glucoside, emodin-8-O-glucoside, and physcion-8-O-glucoside was used as internal reference substance respectively, the RCFs of the other seven components to be measured to the internal reference substances were (1.435, 0.624, 1.206, 0.849, 1.718, 0.563, 0.549), (0.697, 0.435, 0.841, 0.592, 1.197, 0.392, 0.383), (1.603, 2.3, 1.932, 1.36, 2.753, 0.897, 0.88), (0.83, 1.191, 0.518, 0.704, 1.425, 0.464, 0.455), (1.178, 1.691, 0.736, 1.421, 2.024, 0.663, 0.647), (0.582, 0.835, 0.363, 0.702, 0.494, 0.328, 0.32), (1.788, 2.566, 1.117, 2.157, 1.518, 3.072, 0.982) and (1.822, 2.616, 1.137, 2.197, 1.547, 3.13, 1.025), and the RRTs were (1.207, 1.47, 1.68, 1.719, 1.763, 1.768, 2.015), (0.829, 1.218, 1.393, 1.425, 1.461, 1.466, 1.671), (0.681, 0.821, 1.143, 1.169, 1.199, 1.203, 1.371), (0.596, 0.719, 0.876, 1.023, 1.049, 1.053, 1.2), (0.583, 0.703, 0.856, 0.977, 1.026, 1.029, 1.173), (0.568, 0.685, 0.835, 0.953, 0.975, 1.003, 1.143), (0.566, 0.683, 0.832, 0.95, 0.972, 0.997, 1.139) and (0.497, 0.599, 0.73, 0.834, 0.853, 0.875, 0.878), respectively. The PD between the mean values of the contents of eight components calculated by QAMS and the results determined by ESM were less than 3%. Conclusion: The established QAMS method is accurate and feasible, and can simultaneously determine eight anthraquinone glycosides in Rhei Radix et Rhizoma with only one reference substance in practical work.
