With the current worldwide problem of multidrug resistance (MDR) in many microbes, against conventional antibiotics, research is shifting towards the discovery of antimicrobial compounds from plant origin. My research group has been able to test crude plant extracts, including their green-synthesised nanoparticles, with antimicrobial activity, against some known MDR bacteria. We want to identify the actual compounds in the plant extracts, possessing the antimicrobial activity against these MDR bacteria.
