Author(s):
Udai Pratap Singh and Sunil Kumar Mishra
Abstract:
The present study was designated to evaluate the antibacterial activities of ethyl acetate and hot water extract from leaves, fruits and stems of Psidium guajava. Compare to all parts, the stems were showing best result and the zone of inhibition was obtained 24.5 mm. The antibacterial activities of the extracts against bacteria were tested by using agar well diffusion assay and the MIC values were determined by broth dilution assay. The hot water extract showed least antibacterial activity as compare to ethyl acetate extract. The least concentration were obtained 1.98 mg/ml in ethyl acetate extract of stems against P. aeruginosa. The antibacterial compound mainly found in Psidium guajava were tannins, phlobatannins, saponins, terpenoids, alkaloids and poly phenols.
