Study on chromatographic fingerprint of extractive from Tripterygium wilfordii with supercritical carbon dioxide / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To establish the chromatographic fingerprint of supercritical carbon dioxide extract of Tripterygium wilfordii.</p><p><b>METHOD</b>HPLC method was applied for quality assessment of T. Wilfordii, HPLC analysis was performed on Kromasil C18 (4. 6 mm x 250 mm, 5 microm) with the mixture of acetonitrile-1% per thousand H3PO4, as mobile phase in gradient mode. The samples were detected at UV of 267 nm with column temperature of 35 degrees C, analytic time was 80 min; Flow-rate was 1.0 mL x min(-1). The chromatographic fingerprint of ten batches of samples was determined, for establishing the chromatographic fingerprint of T. Wilfordii.</p><p><b>RESULT</b>Indicating 27 peaks in common, identified 21 peaks with chemical reference and HPLC-MS, and the HPLC fingerprint was established.</p><p><b>CONCLUSION</b>The method is steady and accurate with a good repeatability and can be used as a quality control method for T. Wilfordii.</p>
