To develop an HPLC-DAD method for the simultaneous determination of the contents of 5 components (isochlorogenic acid A, isochlorogenic acid C, linarin, rupestonic acid, and chrysosptertin B) in Artemisia rupestris L.
The chromatographic separation was achieved on a InerSustainR C18 (250 mm×4.6 mm, 5 μm) column with acetonitrile (A)-0.2% phosphoric acid (B) as mobile phase at a flow rate of 1.0 mL·min-1 for gradient elution. Isochlorogenic acid A, isochlorogenic acid C, linarin, rupestonic acid and chrysosptertin B were detected at 320, 320, 334, 245, 350 nm, respectively. Injection volume was set at 10 μL. To establish an HPLC chromatographic fingerprint of Artemisia rupestris L., the similarity evaluation was carried out. The cluster analysis was performed by using SPSS 23.0 software.
There were 25 common peaks in HPLC fingerprint of 15 batches of Artemisia rupestris L. The similarities of 10 batches of samples were more than 0.85. The 10 batches of samples can be divided into 2 categories by cluster analysis.
The method is simple, quick, accurate, and helpful for the quality control of Artemisia rupestris L.
