Experimental Research on the Detection Methods for Toddalolactone in Jinji Tablets / 中国药师

ABSTRACT

Objective:To identify toddalolactone and establish the analysis method for Jinji tablets.Methods: An Hypersil DBS C18column(250 mm×4.6 mm,5 μm) was used. The mobile phase consisted of acetonitrile-0.1% phosphoric acid solution. The flow rate was 0.8 ml·min-1and the detection wavelength was at 330 nm. Toddalolactone was identified by an LC-MS method and the re-sult was compared with that of the reference regent.TLC and HPLC analytical methods were used for analysis of toddalolactone.Re-sultsTotally 58 batches of Jinji tablets were tested,and the suspected samples were confirmed by HPLC-MS/MS.Toddalolactone was detected out from 20 batches of samples. Conclusion:The method is simple,rapid and accurate, which is able to detect toddalolac-tone quickly and effectively.
