ABSTRACT
<p><b>OBJECTIVE</b>To develop an HPLC method for the determination of eleutheroside B in As1 (the extract fraction from Acanthopanax senticosus, which has a good effect of antifatigue).</p><p><b>METHOD</b>The antifatigue effect of Asl was evaluated by mice burden swimming testing. One compound was isolated by silica gel, Sephadex LH-20 column chromatography and preparative high performance liquid chromatography. The structure was identified by physicochemical properties and spectral evidences. Eleutheroside B in Asl was determined by HPLC. Chromatographic conditions included Diamonsil C18 column (4.6 mm x 250 mm, 5 microm) and the mobile phase consisting of a mixture of acetonitrile-water-ethanoic acid (10: 90: 0.01). The UV detection wavelength was set at 344 nm.</p><p><b>RESULT</b>As1 showed an excellent antifatigue activity; One compound was isolated from As1 and its structure was identified as Eleutheroside B; The calibration cure was linear in the range of 0.104-20.8 microg (r = 0.9999), the average recovery was 97.68%, RSD 1.4% (n=6).</p><p><b>CONCLUSION</b>This HPLC method is simple,accurate and reliable.</p>
