Abstract:

目的:建立金果榄药材的UPLC指纹图谱,为金果榄药材的质量控制提供依据。方法:采用超高效液相色谱法。色谱条件:色谱柱:Acquity UPLCBEN C18 (2.1 × 100 mm,1.7 μm);流动相A:乙腈;流动相B:0.3%磷酸溶液;流速:0.25 ml/min;检测波长:225 nm;柱温:25℃。结果:建立了10批金果榄药材的指纹图谱。金果榄药材有7个共有峰,多数峰可以达到较好分离,具有较高的相似度。结论:建立的超高效液相指纹图谱有较好的精密度、重复性和稳定性,可作为金果榄质量评价参考。
Objective: To establish UPLC fingerprint of Tinospora sagittata and T. capillipes which is expected to provide standards for the quality control and identification of the Chinese crude drug. Method: The UPLC method was used. Chromatography conditions were Acquity UPLCBEN C18 (2.1 × 100 mm, 1.7 μm) column with gradient mobile phase of acetonitrile and 0.3% phosphate acid. UV detection wavelength was 225 nm, the flow rate was 0.25 ml/min and the column temperature was 25?C. Result: UPLC fingerprints of 10 samples of Tinospora sagittata and T. capillipes were established. 7 mutual peaks were selected as the fingerprint peaks in the samples. Among the obtained fingerprints, most of the detected peaks were separated effectively. 10 samples had higher simi-larities. Conclusion: The established UPLC fingerprint has desirable accuracy, repeatability and sta-bility, which can be used as reference for the quality control of Tinospora sagittata and T. capillipes.
