Determination of Scutellarin in Erigeron beviscapus dosageform by High Performance Liquid Chromatography

A HPLC method for determination of seutellarin in Erigeron beviscapus dosageform was reported. The sample was analyzed on a C18 column with a isogradient mobile phase of acetonitrile:water:HAC:2%H₃PO₄(20.0:77.5:2.0:0.5 V/V/V/V). The scutellarin in a bath Erigeron beviscapus dosageform was determined.The content, standard derivation,variation coefficient were 12.53%,0.63,5.03% respectively. The recovery was 99.34.00%～104.70%. This analysis method is simple,rapid, accurate and can be used in the quantitative determination of scutellarin.
