摘要:

建立了同时测定氧化槐果碱、槐定碱和苦参碱的HPLC(高效液相色谱)方法.用VP-ODS(维普C18柱)150mm × 4.6 mm, 5 μm 色谱柱,柱温40 ℃,流动相为0.01mol/L pH 8.5磷酸盐缓冲溶液-甲醇(40 ∶60),流速 1.0 mL/min,紫外检测器波长215 nm.结果表明,3种生物碱在确定的色谱条件下得到很好的分离,且在所选质量浓度范围20~200 mg/L 内线性关系良好,回收率范围97.2%~102%.

关键词: 氧化槐果碱, 槐定碱, 苦参碱, 高效液相色谱

Abstract:

An HPLC method for simultaneous determination of oxysophocarpine, sophoridine, and matrine was proposed. VP-ODS column (150 mm × 4.6 mm, 5 μm) was used in the experiment. Column temperature was 40 ℃, mobile phase was 0.01 mol/L phosphate buffer solution (pH 8.5)-methanol (40 ∶60), UV detection wavelength was 215nm, and flow rate was 1.0 mL/min. The results indicated that the three kinds of alkaloid were separated effectively and showed good linearity within the selected concentration range.

Key words: oxysophocarpine, sophoridine, matrine, HPLC
