摘要
目的比较当归超微粉碎与当归饮片的质量研究。方法用70%甲醇超声提取30 min,色谱柱:Kromasil C18色谱柱(4.6 mm×250 mm,5μm),流速:1.0m L·min-1,检测波长:316 nm,柱温:25℃,流动相:乙腈-0.05%磷酸水梯度洗脱系统。结果当归超微粉碎后,水溶性成分阿魏酸的含量高于当归饮片中水溶性成分阿魏酸的含量。结论超微粉碎有利于提高当归中水溶性成分阿魏酸的溶出量。
Objective To compare the quality of Angelica ultrafine grinding and Angelica pieces.Methods Methods of extraction and chromatographic is more optimized than method in Pharmacopoeia 2010.The method of ultrasonic extraction was used for 30 min by 70%metha-nol.High performance liquid chromatography ( HPLC ) method for the chromatographic conditions: Column: Kromasil C18 column (4.6 mm ×250 mm,5μm) , flow rate:1.0 mL. min -1 , detection wavelength:316 nm, column temperature:25 ℃, mobile phase:acetonitrile-water gra-dient 0.05% phosphoric acid system.Results The content of ferulic acid of water -soluble components in Angelica was higher than that of Angelica pieces.Conclusion Ultrafine grinding Angelica can improve the dissolution of the water -soluble components of ferulic acid.
