Antibacterial Activity of Spice Extracts against Vibrio Species from Different Area of Uttar Pradesh

Today antibiotic resistance is turning out to be major challenge for the medical world. Thus, focus shifts to medicinal plants and natural sources as an alternative to the antibiotics. Herbal sources of drugs have been of interest since ancient times, thus easily accepted by general population. Considering the rich source and easy availability, five common spices (Cardamom-Elettaria cardamomum, CloveSyzygium aromaticum, AsafoetidaFerula assa-foetida, OreganoOriganum vulgare, GarlicAllium sativum) have been selected for the study to screen them for their antibacterial property against both pathogenic and non-pathogenic species of Vibrio ( V. cholerae, V. parahaemolyticus, and V. vulnificus, V. mimicus and V. alginolyticus). Extraction of the spices were done in three solvents i.e., acetone, ethanol and methanol. The study revealed that the methanolic extracts of oregano and garlic showed a distinct inhibitory effect against V.mimicus and V. cholera respectively. Clove, cardamom and asafoetida also exhibited a range of activities between intermediate to susceptible. Also, some of the extracts of spices showed no activity at all against some or all of the target vibrio species.
