Abstract

Tea is generally prepared by steeping the dried young leaves and buds of Camellia sinensis in a boiled water. Following water, tea is mostly consuming drink in the world. This research project was designed to evaluate different tea samples for various biological assays. Assays including antibacterial, antifungal, antileishmanial and antioxidant were carried out following standard procedures. Antimicrobial activities were include disc diffusion and micro broth dilution methods, while spectrophotometric method was used for antioxidant and anti-leishmanial assays. Our test samples exhibited considerable antibacterial activity against Pseudomonas  aeruginosa and Staphylococcus aureus with MICs of 3.7 µg ml-1. Tapal and Tetly showed considerable inhibitory activities against R. solani with 64 ± 3.6 and 76 ± 45% inhibitions respectively at 10 mg ml-1 concentrations. Likewise, Lipton and Tapal showed 76 ± 54 and 76 ± 57% inhibitory activity against A. niger at 10 mg ml-1 concentrations. Tetly was most effective against L. tropica with IC50 of 293.9 μg/ml. Considerable antioxidant and phenolic, flavonoids contents might be responsible for these pharmacological activities and health benefits associated with the use the selected tea brands
