Two, pharmacologically active medicinal plants, Berberis balochistanica Karel (Berberidaceae) and Teucrium stocksianum Boiss. (Labiatae were selected for biological screening. Methanolic extracts of these plants were fractionated into hexane, ethyl acetate, chloroform, butanol and water, which were used for determination of antifungal, antibacterial and cytotoxic effect.
The antifungal and antibacterial activities of these extracts were determined against 12 fungal and 12 bacterial strains by Agar Well diffusion and disk diffusion assays while cytotoxicity was determined through brine shrimp lethality and flow cytometry. The extracts of B. balochistanica was found to be highly effective against 5 bacteria and 2 fungi tested, it showed very low toxicity at highest concentration while T. stocksianumwas effective against 3 bacterial and 1 fungal strain and was non toxic.
