摘要:目的:建立党参中己糖降解产物5-羟甲基糠醛(5-HMF)的含量测定方法,对党参药材中的5-羟甲基糠醛进行含量测定。方法:采用Agilent Extend-C18(250 mm×4.6 mm,5μm)色谱柱,以乙腈-0.3%醋酸溶液(3∶97)为流动相,检测波长284 nm,流速1.0 mL/min,柱温30℃。结果:5-羟甲基糠醛在浓度为2.538~63.45μg/mL范围内与峰面积具有良好的线性关系(r=0.9998),精密度和重复性的RSD分别为0.8%和2.5%。结论:该方法操作简便,结果准确可靠,可用于党参中5-羟甲基糠醛的含量测定,为进一步评价党参的安全性提供参考。
Objective:To establish the determination method for 5-hydroxymethylfurfural (5-HMF) in Dang-Shen (Radix Codonopsis Pilosulae) and determine its contents. Methods:Agilent Extend-C18 (250 mm×4.6 mm, 5μm) chromatographic column was adopted with the mobile phase of acetonitrile-0.3% acetum (3:97), detection wave-length was 284nm, flow rate was 1.0mL/min, column temperature was 30℃. Results:It showed better linear rela-tionship in the range between 2.538 and 63.45μg/mL and peak area (r=0.999 8), accuracy and repeatability RSD were 0.8%and 2.5%respectively. Conclusion:The method, simple and reliable, could be used to the determination of 5-HMF contained in DangShen, which could provide reference for further assessment of the safety of DangShen.
