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. Tea (Camellia sinensis) is consumed worldwide and is second only to water in its popularity as a beverage. It has ascribed many health benefits viz reduction of cholesterol, protection against cardio – vascular diseases and cancer. By concerning all these studies, we have traced out the presence of phytochemical in Camellia sinensis leave. The phytochemical analysis showed the presence alkaloids, flavonoids, steroids and tannins by changing the colour of medium when treated with respective reagents. One gram of Camellia sinensis leaves extract contained 0.7 grams of phenolic compounds. While flavonoid content was 14 mg/gram of Camellia sinensis leave extract. one gram of leaf extracts contained 0.11 gram of reducing power. The methanolic extract of Camellia sinensis showed the presence of various functional groups when run through Fourier transforms infrared spectroscopy. The methanolic extract of Camellia sinensis showed the antimicrobial activity against Bacillus subtilis, and Enterococcus sp. It reveals the highest zone of inhibition around the bacterial colonies when compared with standard antibiotics Erythromycin, Tetracycline and Ampicillin.
