Quantification of isopimpinellin in root of Toddalia asiatica by HPLC / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To determine the content of isopimpinellin in root of Toddalia asiatica.</p><p><b>METHODS</b>A HPLC method was set up. Using Hypersil C18 column and methanol-water (70:30) as mobile phase, with the detection wavelength at 306 nm.</p><p><b>RESULT</b>The linear range of isopimpinellin was 0.004 20 approximately 0.420 microg. The average recovery was 99.7% and the RSD 2.8%.</p><p><b>CONCLUSION</b>The method is simple and accurate, with good reproducibility, and can be used as a quantitative analysis method for isopimpinellin.</p>
