ABSTRACT
<p><b>OBJECTIVE</b>To establish a HPLC-ELSD method for simultaneous determination of trillin and desgalactotigonin contents in Solanum lyratum.</p><p><b>METHOD</b>A Diamonsil C18 column (4.6 mm x 250 mm, 5 microm) was adopted, with the mobile phase consisting of acetonitrile-10 mmol x L(-1) ammonium acetate (52 48). The temperature was 25 degrees C, the flow rate was set at 0.6 mL x min(-1), and the sample size is 20 microL. The temperature of drift tubes and gas flow rate of the detector were set at 95 degrees C and 2.3 L x min(-1), respectively.</p><p><b>RESULT</b>With in the linear ranges of 20-200 mg x L(-1) and 10-100 mg x L(-1), trillin and desgalactotigonin show a good linear relationship. The average recovery was 99.4% (RSD 0.90%) for trillin and 100.3% (RSD 1.1%) for desgalactotigonin.</p><p><b>CONCLUSION</b>The method is so accurate and easily reproducible that it is suitable for the quality control of S. lyratum medicinal materials.</p>
