摘要
目的建立决明子药材中橙黄决明素的高效液相色谱法(HPLC)含量测定方法,并对不同产地决明子进行了含量测定。方法采用HPLC法,色谱条件:Diamonsil^TM(C18,5μm,150mm×4.6mm)HPLC色谱柱,甲醇旬.1%磷酸溶液(60:40)为流动相,检测波长285nm。结果橙黄决明素在进样量0.2~2P,g(r=0.9998)范围内呈良好的线性关系,平均加样回收率为97.96%,RSD为1.61%。结论:所建立的方法准确、简便、快速,重现性好,可作为决明子质量评价标准之一;不同产地的决明子质量有一定的差异。
Objective To set up a simple and accurate method for the determination of aurantio - obtusifolin in Semen Cassiae by HPLC, and to study the content of aurantio - obtusifolin of Semen Cassiae from different sources. Methods Aurantio-obtusifolin was determined by HPLC. Chromatographic conditions concluded DiamonsilTM (Ct8,5 μm, 150 mm × 4.6 mm)column and the mobile phase consisting of methanol-0.1% phosphoric acid (60: 40). Aurantio -obtusifolin was detected at 285nm wavelength. Results The calibration curves of aurantio - obtusifolin were in good linearity over the range of 0.2 - 2 g ( r = 0.999 8 ). The average recovery of aurantio - obtusifolin was 97.96% ( n = 6, RSD = 1.61% ). Conclusion This is simple and accurate that can determine aurantio- obtusifolin, which will be helpful to quality assessment of Semen Cassiae.
