Study on HPLC fingerprint of Swertia mussotii var. mussotii from north-west area of Sichuan Province I / 中国中药杂志

<p><b>OBJECTIVE</b>To constitute HPLC fingerprint of the methanol extract from Swertia mussotii grown in Sichuan Province.</p><p><b>METHOD</b>RP-HPLC, methanol and water including 0.02% acid as mobile phase, gradient elution, flow rate 1.0 mL x min(-1), the detection wavelength was 260 nm, temperature was 30 degrees C.</p><p><b>RESULT</b>The RSD values of peak area and retention time of common peaks in precision, repeatability and stability were lower than 5.0%, respectively, similarity was over 0.805 in S. mussotii collected from 10 different habitats.</p><p><b>CONCLUSION</b>All results above exhibit that this method is simple, practicable, and reliable as a standard method in controlling the quality of S. mussotii.</p>
