Abstract

This study was carried out to evaluate cytotoxic effects of Ajuga multiflora Bunge extracts on murine leukemia tumor $(P388D_1)$ cell lines. Disruptions in cell organelles were determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazoliumbromide (MTT) assay. The comparison of $IC_{50}$ values of Ajuga multiflora Bunge extracts in L1210 and $P388D_1$ cell lines showed that their susceptibility to these extracts decreased in the following order: Adriamycin>methanol extract>chloroform extract>ethyl acetate extract>hexane extract>water extract by the MTT assay. In order to develop an antimicrobial agent, dried Ajuga multiflora Bunge was extracted with several solvents, and then antimicrobial activity was investigated. The minimal inhibitory concentration (MIC) of the extract against microorganisms were also examined. Antimicrobial activities of amocla and ketoconazole as references were compared to those of extracts of $H_2O$, n-hexane, chloroform, ethyl acetate and methanol. The antimicrobial activity of all extracts from the sample had growth inhibition activity against gram-negative bacteria, gram-positive bacteria and fungi $(MIC>200\;{\mu}g/ml)$. These results suggest that the methanol soluble extract of Ajuga multiflora Bunge may be a valuable choice for the studies on the treatment of murine leukemia tumor cell lines.
