Abstract
In the present study, the antifungal and antibacterial properties of three selected plants namely Amphineuron extensus, Hedyotis diffusa and Vitex negundo used in the preparation of rice beer starter culture cakes were evaluated against Aspergillus niger, Aspergillus flavus and E. coli. A. extensus showed the highest inhibition zone against A. niger at 20% concentration whereas H. diffusa showed the lowest MIC value of 1.25%. In case of A. flavus, V. negundo showed the highest Inhibition zone at 20% concentration and all the plant extracts exhibited MIC value of 5%. A. extensus showed the highest inhibition zone against E. coli followed by V. negundo and H. diffusa at 20% concentration. A. extensus also exhibited the lowest MIC value of 1.25% against E. coli. The antioxidant capacity of the methanol extracts was also estimated using DPPH method. V. negundo has the highest antioxidant capacity in comparison to other two plant extracts. These findings suggest the potential antimicrobial and antioxidant properties of the plant extracts and also their possible contribution to the overall medicinal and therapeutic benefits of rice beer.
