    Abstract:
    OBJECTIVE: To establish the chromatographic fingerprint of supercritical carbon dioxide extract of Tripterygium wilfordii. METHOD: 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. RESULT: Indicating 27 peaks in common, identified 21 peaks with chemical reference and HPLC-MS, and the HPLC fingerprint was established. CONCLUSION: The method is steady and accurate with a good repeatability and can be used as a quality control method for T. Wilfordii.
