摘　　要：菊科草本植物的野菊花主要含有萜类、黄酮、挥发油等成分，具有清热解毒、消肿功能。对葡萄球菌、白喉杆菌、链球菌、绿脓杆菌、痢疾杆菌、流感病毒均有抑制作用。临床用于上感、流感、急性化脓性炎症、咽喉肿痛、高血压、目赤肿痛等疾病的治疗拉。野菊花在全国各地的分布很广，A new FIA differential spectrophotometry determining the content of flavones in Chrysanthemum indieum L. is invented in the test. Basing on that flavonone changes into its relevant isomer （λmax = 405nm） in alkaline medium, we improve the determination by FIA differential spectrophotometry. The plus-minu inflexions （A1 ,A2 ,A3 ） happens in a sample introduction. We discover that the sampling frequency is 120 times·h^-1 , the linear range is 1.05 -50μg ·mL^-1 , and the related coefficient is 0.9997 through the analysis of A =A1 ＋A2 ＋A3. We are satisfactory with the results in the test.
