Phytochemical Screening and Antibacterial Activity of Globimetulla browni Extracts During Wet Season

The study investigated the phytochemical composition of Globimetulla browni for it’s ascribed folkloric medicinal uses as an antidiabetic and to establish its Antibacterial potency (if any). A comparative investigation was carried out and season did not have any effect on the phytochemical/Antibacterial potency of this plant. The ethanolic and aqueous extracts significantly affected both gram-negative and gram- positive microorganisms during wet season (May - September). Globimetulla browni is a specie of African mistletoe and is hemi-parasitic in nature growing on many trees e.g., Eukalyptus and has ascribed medicinal uses. Phytochemical screening showed the presence of carbohydrates, alkaloids, tannins and flavonoids. The ethanolic and aqueous extracts inhibited the growth of Klebsiella aerogenes, Proteus spp., Escherichia coli and Pseudomonas aeruginosa. Gentamycin and Cloxacillin did not exhibit any activity against Pseudomonas aeruginosa.
