Abstract

Medicinal plants possess an important source of pharmacological effects that acts as new anti-infections, antioxidant and anti-cancer agents. The most important bioactive constituents of plants are steroids, terpenoids, carotenoids, flavonoids, alkaloids, tannins and glycosides which serve a valuable starting material for drug development. Green tea (Camellia sinensis) is widely consumed worldwide. Green tea, the most common type of tea consumed in Asia, contains a large amount of non-oxidized flavonoids, named catechins. There is also evidence that green tea reduces oxidative stress and reverses endothelial dysfunction. The research was conducted to analyze the antimicrobial and antioxidant properties of Camellia sinensis (green tea). Keeping in view the importance of flavonoids and other bioactive components this study focused on assessing biological activities using different extracts at different temperature treatments. The disc diffusion method was used to assess the antimicrobial potency of the methanolic and aqueous extracts of Camellia sinensis. It was observed that all tested microbial strains were sensitive (>0.82 activity index) to methanolic extract that displayed a higher antimicrobial effect. There was no effect of temperature on the green tea extracts as it followed the same results in case of antimicrobial assay. Similarly, methanolic extract of green tea had high total phenolic (0.33mg/g) and flavonoid contents as compare to aqueous extracts. The present findings show that methanolic extract of Camellia sinensis had some high biological activities.
