Antioxidant, antimicrobial and cytotoxic bioassay of Mollugo oppositifolius L

Md. Torequl Islam, Md. Ahad Ali Khan, Jasmin Akther Hossain, Joy Barua


The present study was conducted according to the traditional uses of Mollugo oppositifolius L. by the kabiraj (traditional practioner) for the treatment of infectious diseases of the ill fated and poor people of Bangladesh. For this antioxidant, antimicrobial and biolethality potentials were conducted by methanol (MOME), ethanol (MOEE) and petroleum ether (MOPE) extractives of the suspected species. To determine the antioxidant activity the DPPH inhibition method was used. For antimicrobial test, antibacterial and antifungal
sensitivities were performed by disc diffusion method and serial tube dilution method was carried out to determine the minimum
inhibitory concentrations on some human pathogenic bacteria and fungi. For cytotoxicity test, brine shrimp lethality bioassay was conducted. Among the three crude extracts, MOEE produced more significant inhibition of DPPH (IC50; 27 μg/ml); MOPE produced highest zone of inhibition against Bacillus subtilis (16.67 mm) and Microsporum spp. (16.0 mm). On the other hand, MOME produced mild cytotoxicity as 50% and 90% mortality (LC50 and LC90) 8.0 μg/ml and 85.12 μg/ml.
Key words: Antioxidant, antimicrobial, cytotoxicity, Mollugo oppositifolius
