Aim of study: The aim of this study is to put forward the antimicrobial activity of cold pressed oils obtained from seeds of nettle (Urtica dioica), radish (Raphanus sativus) and pomegranate (Punica granatum). Material and Methods: Oils of these seeds were analysed for their antibacterial and antifungal activities by the disk diffusion and MIC tests against fifteen microorganisms,
In vitro evaluation of aqueous extract of leaves of Cicer arietinum against five fungi namely F. oxysporum , Aspergillus flavus, Curvularia lunata, Cladosporium cladosporioides and Penicillium sp. Among the five fungi tested, A.flavus recorded maximum antifungal activity of 93.0% inhibition at 50%concentration tested. In 40% of aqueous extract it was recorded 78.3% inhibition and moderate activity was observed in 20 and 30% concentration and recorded 63.3% and 49.3% respectively. A.flavus was followed by Penicillium species and was recorded 91.3% inhibition at 50% concentration. In 30 and 40% concentration it was recorded 671% and 79.3% inhibition respectively. Least activity was observed in 10% concentration. In F.oxysporum, at 50% concentration, 88.0% inhibition was recorded followed by 67.2%, 51.1%, 35.2% and 22.0% inhibition in 40, 30, 20 and 10% concentration tested. C.lunata recorded significant activity of 80.3% inhibition in 50% concentration and least inhibition was observed in 10% concentration(15.0%). In C.cladosporioides it was recorded 74.5% inhibition in 50% concentration and at 10% concentration , it was recorded 25.3% inhibition. M oderate activity was observed in 20, 30 and 40% concentration. Compared to synthetic fungicide Dithane M 45 and Bavistin at 2.0% recommended concentration, 100% inhibition was observed in all the test fungi.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
