| Abstract:Objective:To determine the content of luteolin in three kinds of Chrysanthemum morifolium that are often seen in market by HPLC.Methods: The luteolin was quantified by reverse-HPLC on Diamosil C18 column(250 mm×4.6 mm,5 μm)using methanol-water(changed from 50∶50 to 80∶20 in 30 min at pace) as mobile phase with a flow rate of 1 mL/min.The detecting wavelength was 350 nm.Results:The linear range of luteolin was 0.224 ～2.24 μg(r=0.999 9).The average recovery was 99.40%,and RSD was 2.67%(n=9).The average content of luteolin in Hangju,Gongju and Haoju was 0.34,0.41,0.69 mg/g,and RSD was 0.8%,1.2%,1.3%,respectively.(n=6).Conclusion:The content of luteolin in Haoju was the highest.The established method is delicate,simple,convenient,accurate,reproducible,and suitable for the quality control of luteolin in defferent kinds of Chrysanthemum morifolium that are often seen in market. |
