ABSTRACT
Objective To establish a QAMS method for content determination of six compositions (chlorogenic acid, caffeic acid, cryptochlorogenin acid, isochlorogenic acid A, isochlorogenic acid C and loganin) from Lonicerae Japonicae Caulis; To verify the feasibility and applicability of this method in quality control of Lonicerae Japonicae Caulis. Methods Chlorogenic acid was set as internal reference substance. The HPLC analysis was performed on a Waters Symmetry C18 column (4.6 mm × 250 mm, 5 μm) with a mobile phase consisted of acetonitrile and 0.4% phosphoric acid solution in gradient elution manner at a flow rate of 1 mL/min. The column temperature was maintained at 35 ℃, and the detection wavelength was set at 327 nm for chlorogenic acid, caffeic acid, cryptochlorogenin acid, isochlorogenic acid A, isochlorogenic acid C and 236 nm for loganin. Results The relative correction factors of caffeic acid, cryptochlorogenin acid, isochlorogenic acid A, isochlorogenic acid C and loganin were established; there was no obvious difference between calculated value of QAMS and measured value of external standard method. Conclusion The quality control mode of QAMS can be used for multi-index synchronization quality evaluation of the six compositions from Lonicerae Japonicae Caulis.
