【摘要】 确定肤痒茶剂质量标准。通过薄层鉴别方法对处方中地肤子、苍耳子、红花进行定性鉴别。运用高效液相色谱法对川芎中的阿魏酸进行含量测定。定性鉴别能从样品中检出相应的斑点。含量测定阿魏酸量在0.0222~0.1110μg有良好的线性关系,回收率101.02%,RSD=1.81%。所建立的方法可靠,能准确地进行定性、定量检测,可用于该制剂的质量控制。更多还原

【Abstract】 To establish the quality standard for Fuyang tea.Kochia scoparia(L.)Schrad.、Xanthium sibiricum Patr.and Carthamus tinctorius L.were identified by TLC.Ferulic Acid was determined by an HPLC method:A good linear relationship between peak area and concentration of ferulic acid was found at the range of 0.0222～0.1110μg with a correlation coefficient of A=0.9993.The average recovery of ferulic acid was 101.02% and RSD was 1.81%(n=5).The method is reliable,accurate and specific.It can be used for the quality control of Fuyang tea.更多还原
