Abstract:
Plant secondary metabolites provide a vital role for the medicinal activity of plant species. This study was conducted to assess the phytochemical constituents in Punica granatum L. Leaf extracts using standard methods. The qualitative analysis of bioactive compounds for the three extracts have been analysed in this study and there is wide range of phytochemical compounds present in the three extracts. Ethanolic extract and hydro alcoholic extract was found to have a wide range of bioactive compounds like alkaloids, carbohydrates, coumarins, flavonoids, proteins, phenols, reducing sugars, steroids and tannins. The ethanolic leaf extract was tested against Gram positive and Gram negative bacterial pathogens. Antimicrobial activity of six bacterial species and three fungal species were employed as test organism. These include Streptococcus pyogenes, Salmonella typhi, Klebsiella pneumonia, Staphylococcus aureus, Heliocabacter pylori and Psudomonas auroginosa. The fungal species such as Aspergillus niger, Candida albicans and Trichoderma viride were prevent by Punica granatum. The result of this proposed study enlightened the evidence that, P. granatum contains various bioactive compounds that may be useful in the synthesis of therapeutic drugs and also suggest the herbal medicine. The therapeutic effect of this plant may be accounted for its counteracting action on free radicals in vivo.
