Study on UPLC Fingerprint of Tinospora sagittata and T. capillipes
Abstract: Objective: To establish UPLC fingerprint of Tinospora sagittata and T. capillipes which is expected to provide standards for the quality control and identification of the Chinese crude drug. Method: The UPLC method was used. Chromatography conditions were Acquity UPLC®BEN C18 (2.1 × 100 mm, 1.7 µm) column with gradient mobile phase of acetonitrile and 0.3% phosphate acid. UV detection wavelength was 225 nm, the flow rate was 0.25 ml/min and the column temperature was 25˚C. Result: UPLC fingerprints of 10 samples of Tinospora sagittata and T. capillipes were established. 7 mutual peaks were selected as the fingerprint peaks in the samples. Among the obtained fingerprints, most of the detected peaks were separated effectively. 10 samples had higher simi-larities. Conclusion: The established UPLC fingerprint has desirable accuracy, repeatability and sta-bility, which can be used as reference for the quality control of Tinospora sagittata and T. capillipes.
