GC-MS evaluation of bioactive phytochemicals of commercial green teas (Camellia sinensis) of India

摘要

Objective: An attempt has been made to identify the presence and composition of bioactive phytochemcials present in six commercial green tea (Camellia Sinensis) samples acquired from diverse locations of India. Methods: Gas chromatography-mass spectroscopy technique was used for the qualitative and quantitative analysis of the phytochemicals present in the green tea samples. Results: The results indicated the presence of various secondary metabolites like pyrogallol, quinic acid, caffeine, xanthine alkaloid palmitic acid, diterpene, linolenic acid in the studied samples. Conclusion: The total peak area percentages of health beneficial phytochemicals in the green tea samples were in the range of 83 to 96.
