摘要: 目的:建立油菜花粉药材定性与定量检测方法,为油菜花粉药材的质量控制提供科学依据。方法:采用薄层色谱法,以油菜花粉对照药材和β-谷甾醇为对照,以硅胶G为固定相,展开剂分别为乙酸乙酯-丁酮-甲醇-水(5∶3∶1∶1),环己烷-乙酸乙酯-冰醋酸(9∶2∶0.2),建立黄酮类成分及甾醇类成分的鉴别方法。采用高效液相色谱(HPLC)法,使用Sepax BR-C18(4.6 mm×250 mm,5μm)色谱柱;以甲醇-0.4%磷酸溶液(50∶50)为流动相,流速1.0 mL·min-1;柱温30 ℃;检测波长360 nm。以槲皮素(C15H10O7)和山柰素(C15H10O6)的总量计,测定油菜花粉药材中总黄酮的含量。结果:在薄层色谱鉴别中,供试品分别检出与油菜花粉对照药材及β-谷甾醇对照品相应的斑点;含量测定中,槲皮素在6.45~32.27 μg·mL-1范围内线性关系良好,相关系数为0.999 9;山柰素在12.14~60.72 μg·mL-1范围内线性关系良好,相关系数为0.999 9;槲皮素平均回收率为102%(RSD=3.3,n=6),山柰素平均回收率97%(RSD=1.4,n=6),精密度、稳定性和重复性试验的RSD均不大于2.0%(n=6)。10批油菜花粉中总黄酮含量范围为0.28%~0.38%。结论:建立的油菜花粉定性、定量检测方法操作简捷,重复性及稳定性良好,可作为油菜花药材的质量控制方法。

Abstract: Objective:To establish the methods for qualitative and quantitative detection of rape pollen, and to provide scientific basis for the quality control of rape pollen.Methods:β-sitosterol and reference herbs were used to the qualitative identification of rape pollen by TLC. Silica gel G was used as the stationary phase, and the developing agents were ethylacetate-butanone-methanol-water(5∶3∶1∶1) and cyclohexane-ethylacetate-acetic acid(9∶2∶0.2). The HPLC method was used to determine the content of total flavonoids (quercetin andkaempferol) in rape pollen.The Sepax BR-C18 column (4.6 mm×250 mm,5 μm) was used, and methanol-0.4% phosphoric acid solution(50∶50)was used as the mobile phase. The detection wavelength was 360 nm. The flow rate was 1.0 mL·min-1. The column temperature was 30 ℃. The content of total flavonoids in rape pollen was determined based on the total amount of quercetin (C15H10O7) and kaempferol (C15H10O6). Results: In TLC identification chromatogram, spots corresponding to rape pollen reference herbs and β-sitosterol control were detected in the test samples.The liner relationship of quercetin was good in the range of 6.45-32.27 μg·mL-1, and the correlation coefficient was 0.999 9. The liner relationship of kaempferol was good in the range of 12.14-60.72 μg·mL-1, and the correlation coefficient was 0.999 9. The average recovery of quercetin was 102%(RSD=3.3, n=6), and the average recovery of kaempferol was 97% (RSD=1.4,n=6). The RSDs of precision, stability (24 h) and reproducibility tests were all lower than 2.0%(n=6). The content of total flavonoids in 10 batches of rape pollen ranged from 0.28% to 0.38%.Conclusion: The TLC identification method and the HPLC method established for the qualitative and quantitative detection of rape pollen were fast, accurate and reproducible, which provides a scientific basis for the quality control of rape pollen.
