Abstract
OBJECTIVE To establish a method for determination of homoarbutin in six species of Pyrola by HPLC.METHODS Samples were extractd by methanol . The HPLC method was chromatographed on synchrom Si column(5 μm,150 mm×4.6 mm) and the mobile phase was hexane-ethyl acetate-methanol(30∶10∶9).The homoarbutin was detected at 280 nm.RESULTS The linearity was good within the range of 0.524~2.640 μg ( r = 0.9999 ). The average recovery was 96.68%( n =6).CONCLUSION It can be used for quality control in Herba Pyrolae
