摘要
In the present study, extracts of CHCl3, n-BuOH and water of Lomatogonium carinthiacum were tested for their possible anticancer effects on human lung adenocarcinoma A549 cell line, human erythroleukaemia K562 cell line and human cervical carcinoma HeLa cell line. The inhibitory effect of the extracts on cell proliferation was assessed by MTT colourimetric assay invitro. A high-performance liquid chromatography-electrospray-mass spectrometric (HPLC-EIS-MS/MS) method was developed for the determination of the constituents of the extracts. According to HPLC-EIS-MS/MS data, the chemical structures of 21 constituents of L. carinthiacum were identified on-line without time-consuming isolation. The L. carinthiacum extracts showed inhibitory effects on the abovementioned cell lines. Extracts of CHCl3 were found to be the most inhibitory, with IC50 values of 0.13, 0.75 and 0.60 mu g mL-1 on A549, K562 and HeLa, respectively. According to the IC50 values, the order of sensitivity of the cell lines was A549 HeLa K562 and the inhibitory effects to the cell lines of these extracts were in the order CHCl3 extract water extract n-BuOH, as xanthones iridoids and secoiridoids flavonols. The present study showed inhibitory activity of L. carinthiacum extracts on tumour cells.
