ABSTRACT
Objective To develop the quality standard for Lajiao Fengshi Plaster. Methods Identification for menthol and borneol were established by gas chromatography SP-2000A. The content of capsaicin, an activity component from capsicum which is the main ingredient of Lajiao Fengshi Plaster, was determined by Kromasil C18 chromatogram columniations(250 mm?4.6 mm, 5 ?m)mobile phase of aqueous acetonitrile-0.17%phosphoric with gradient elution method, velocity of flow 1.0 ml/min, and detection wavelength 209 nm. Results The retention time of menthol and borneol is consistent with that of the main ingredient of the reference substance. The good liner range of capsaicin reference substance on calibration curve was 0.03952~0.3952 ?g (r=0.9995), and the average recovery was 96.61%, RSD=0.30%. Conclusion The method is sensitive, specific, and repeatable. It could be used in quality control for Lajiao Fengshi Plaster.
