Quantative analysis of eupatilin and jaceosidin in folium of Artemisia argyi from different areas in China by RP-HPLC based on ancient medicine books
In order to evaluate the quality of Artemisia argyi from Qichun,Ningbo,Anguo and Nanyang,the contents of eupatilin and jaceosidin were determined by RP-HPLC.The determination was performed on Agilent Eclipse XDB-C18 (4.6 mm × 250 mm,5 μm) with mobile phase consisted of acetonitrile-0.2％ phosphoric acid(35:65) at the flow rate 1.0 mL · min-1.The detection wavelength was 350 nm and the column temperature was 25 ℃.The results showed that the amount of eupatilin and jaceosidin had a clear linear relationship in the range of 0.003-0.126 g · L-1 (r =0.999 9) and 0.005-0.200 g · L-1 (r =0.999 9),and the average recovery rates for them were 99.14％ (n =6,RSD 1.2％) and 99.40％ (n =6,RSD =0.73％),respectively.The results showed that RP-HPLC can be used for the quantification of eupatilin and jaceosidin in the folium ofA.argyi.With this method,we found there was no significant difference of jaceosidin content within all the samples collected,but the content of eupatilin was significantly higher in samples from Qichun,Ningbo,Xiangyang and Nanyang,located in the south of Huaihe River compared with these from other areas.
