DETERMINATION OF CATECHIN CONTENTS IN S3A3 AND TV18 TEA CULTIVAR USING HPLC METHOD.

Conventional characterization of catechin content in fresh tea leaves refers to the quantification of (-)-EGCG, (-)- ECG, (-)- EGC, (-)- EC, and (+)- C for their medicinal benefits. For the two tea cultivars S3A3 and TV18, being cultivated in NE India, the article targets a detailed catechin profile and a comparative assessment with the best findings in the literature. The investigations affirmed that the chosen tea cultivar leaves possessed higher constitution of galloyl catechins (EGCG & ECG). Also, while EC and C are in low concentrations, EGC concentration has been very high. Henceforth, both S3A3 and TV18 can be customized as promising sources for the development of functional tea beverage products. [ABSTRACT FROM AUTHOR]
