摘要:建立槐枝的薄层色谱(TLC)鉴别及高效液相色谱(HPLC)法测定其中芦丁含量的方法。样品中加入石 油醚(30~60 ℃)脱色,然后用甲醇超声提取,以乙酸乙酯-甲醇-甲酸-水(体积比为8∶1∶1∶1)为展开剂,建立槐 枝的薄层色谱鉴别方法。选用Kromasil C18 柱(250 mm×4.6 mm,5 μm)为分离柱,流动相为甲醇-1% 冰醋酸溶液 (体积比为32∶68),流量为1.0 mL/min,柱温为36 ℃,采用HPLC 法测定芦丁含量,检测波长为257 nm。芦丁的质 量在45.3~226.5 ng 范围内与色谱峰面积具有良好的线性关系,相关系数为1.000,方法检出限为1.54 ng。测定结果 的相对标准偏差为1.6%(n=6),样品加标回收率为98.7%~102.2%。所建立的薄层色谱鉴别方法及高效液相色谱法 测定其中芦丁含量的方法可以有效控制槐枝的质量。 
Abstract:A method of identification of Sophora japonica by thin layer chromatography(TLC) and determination of rutin by high performance liquid chromatography(HPLC) was established. Petroleum ether (30-60 ℃ ) was added to the sample for decolorization, and then ultrasonic extraction with methanol. Ethyl acetate-methanol-formic acid-water (volume ratio was 8∶1∶1∶1) was used as the developer to establish the TLC identification method of Sophora japonica. Kromasil C18 column (250 mm×4.6 mm, 5 μm) was used as separation column, the mobile phase was methanol-1% glacial acetic acid solution (volume ratio was 32∶68), the flow rate was 1.0 mL/min, the column temperature was 36℃, the rutin content was determined by HPLC, and the detection wavelength was 257 nm. The mass of rutin had a good linear relationship with the chromatographic peak area in the range of 45.3-226.5 ng, the correlation coefficient was 1.000, and the detection limit was 1.54 ng. The relative standard deviation of determination results was 1.6%(n=6), and the recoveries of the standard addition were 98.7%-102.2%. The established TLC identification method and HPLC method can effectively control the quality of Sophora japonica.
