ABSTRACT
<p><b>OBJECTIVE</b>To establish a quantitative method of simultaneously determination of swertiamarin, gentiopicroside, mangiferin, swertianolin, isoorientin, 1,8-drihydroxy-3-methoxy-xthanone in Swertia from Qinghai province and Sichuan province by HPLC.</p><p><b>METHOD</b>The samples were separated on the column of Kromasil C18 (4. 6 mm x 250 mm, 5 microm) which eluted with methanol and water (content 0.02% phosphoric acid). The ratio of methanol increased from 20% to 80% during 20-50 min, and from 80% to 100% during 50-60 min, with detected wavelength 254 nm, flow rate at 1 mL x min(-1), column temperature 35 degrees C.</p><p><b>RESULT</b>Six compounds were base-isolated, the linear ranges of swertiamarin, gentiopicroside, mangiferin, 4-swertianolin, 5-isoorientin, 1,8-drihydroxy-3-methoxy-xthanone were excellent.</p><p><b>CONCLUSION</b>The method was rapid and precise, and can be use for controlling medicinal materials quality.</p>
