Abstract
This study was designed to examine in vitro antibacterial activities of essential oils extracted from 53 aromatic plants of Gorakhpur Division (UP, INDIA) for the control of two phytopathogenic bacteria namely Erwinia herbicola and Pseudomonas putida causing several post-harvest diseases in fruits and vegetables. Out of 53 oils screened, 8 oils such as Chenopodium ambrosioides, Citrus aurantium, Clausena pentaphylla, Hyptis suaveolens, Lippia alba, Mentha arvensis, Ocimum sanctum and Vitex negundo completely inhibited the growth of test bacteria. Furthermore MIC & MBC values of C. ambrosioides oil were least for Erw. herbicola (0.25 & 2.0 ?l/ml) and Ps. putida (0.12 & 1.0 ?l/ml) respectively than other 7 oils as well as Agromycin and Streptomycin drugs used in current study. GC and GC-MS analysis of Chenopodium oil revealed presence of 125 major and minor compounds, out of them, 14 compounds were recognized. The findings concluded that Chenopodium oil may be regarded as safe antibacterial agent for the management of post-harvest diseases of fruits and vegetables.
