Camellia sinensis (CS) is an evergreen shrub commonly known as Teyaku belongs to the family Theaceae. It grows best in the moist, tropical climates found in Northeast India and many provinces in China. It is also well grown in Japan, Srilanka, Kenya and Turkey etc. Twigs of Camellia sinensis were collected from Kannan Devan Tea Plantation, Munnar. Authentication was done by Professor Ravi Prasad, Department of Botany, S.K University, Anantapur. Voucher specimens were preserved in the herbarium with voucher numbers SK871. In the present study twigs of the plant are defatted with petroleum ether and extracted by maceration for 72hrs with an optimized solvent, n-butanol. The Percentage yield was 45.66%. preliminary phytochemical screening is done and found various phytoconstituents like Alkaloids, Tannins, Flavonoids, Glycosides, Phenols and Terpenoids, various physiological parameters like Loss on Drying, Total ash, Acid insoluble ash, Water soluble ash, Swelling Index, Foaming index were performed. The total phenolic contents were estimated as 128.92±0.149% w/w equivalent of gallic acid respectively. Flavonoid contents were found as 41.13±0.672mg/g quercitin equivalent respectively. My further studies are aiming to structural elucidation and the anticancer activities of specific compounds in the extract.
