Eight plants were screened for their potential antimicrobial activity. The plants
screened were Azadirachta indica (Meliaceae), Emblica of icinalis
(Phyllanthaceae), Terminalia arjuna (Combretaceae), Calendula of icinalis
(Asteraceae), Ficus benghalensis (Moraceae), Vinca rosea (Apocynaceae), Mangifera indica (Anacardiaceae) and Mentha piperita (Lamiaceae). The activity was tested using agar well diffusion method against 13 microbes that includes six
bacterial strains and seven fungal strains. Among the three solvents used the
extractive yield was maximum with methanol. Proteus vulgaris, among bacteria was observed to be the most resistant one, slightly inhibited by n-hexane extract of Calendula officinalis (leaf), methanolic extract of Emblica officinalis (leaf) and methanolic extracts of Calendula officinalis. Antifungal activity was found to be
less in case of all the extracts except in case of methanolic extracts of Emblica
officinalis (fruit) and n-hexane extract of Azadirachta indica which considerably
inhibited Aspergillus fumigatus and Cladosporium herbarum respectively |
