Versatile Health Benefits of Catechin from Green Tea (Camellia sinensis)

Abstract

Background: Tea (Camellia sinensis, Theaceae) is the second most consumed beverage in the world. Green tea is the least processed and thus contain rich antioxidant level, and believed to have most of the health benefits. </p><p> Methods: We commenced to search bibliographic collection of peer reviewed research articles and review articles to meet the objective of this study. </p><p> Results: From this study, we found that the tea beverage contains catechins are believed to have a wide range of health benefits which includes neuroprotective, anti-inflammatory, antiulcer, antiviral, antibacterial, and anti-parasitic effects. The four major catechin compounds of green tea are epigallocatechin (EGC), epicatechin (EC), epigallocatechin gallate (EGCG), and epicatechin gallate (ECG), of which EGCG is the major constituent and representing 50-80% of the total catechin content. And also contain xanthine derivatives such as caffeine, theophylline, and theobromine, and the glutamide derivative theanine. It also contains many nutritional components, such as vitamin E, vitamin C, fluoride, and potassium. We sum up the various green tea phytoconstituents, extraction methods, and its medicinal applications. </p><p> Conclusion: In this review article, we have summarized the pharmacological importance of green tea catechin which includes antioxidant potential, anti-inflammatory, antimicrobial, anticancer, antidiabetic and cosmetic application.

Physicochemical characteristics and antiproliferative and antioxidant activities of Moroccan Zantaz honey rich in methyl syringate

“…Syringic acid and catechin, which are related to methyl syringate and epicatechin, respectively, followed in abundance. Health promoting properties such as antioxidant and antiproliferative activities have been found in all these polyphenols (Gheena & Ezhilarasan, 2019;Natarajan et al, 2019;Qu et al, 2020).…”

Mycotoxins Detection and Fungal Contamination in Black and Green Tea by HPLC-Based Method

“…These substances can also reduce the formation of free radicals in the body which have an important role in aging and precursing many forms of diseases. Tea also contains many dietary components, including vitamin E, C, fluoride, and potassium [ 4 , 5 ]. Mycotoxins are secondary fungal metabolites that produced by specific strains of mold (fungi) which are famous as potential top priority human's health hazard.…”

The influence of in vitro gastrointestinal digestion on the Perilla frutescens leaf extract: Changes in the active compounds and bioactivities

“…Many reports have reported that RA is the predominant phenolic compound found in P. frutescens , and it possesses antioxidant, anti‐allergic, antidiabetic, anticancer, antimicrobial, and anti‐inflammatory properties (Swamy et al., 2018; Zhu et al., 2014). SA, CA, and (+)‐catechin are the phenolic and flavonoid compounds often found in tea, coffee, fruits, vegetables, and plants, which exhibit functional properties such as antioxidant, anticancer, antimicrobial, antidiabetic, and anti‐inflammation (Bagdas et al., 2019; Natarajan et al., 2017; Srinivasulu et al., 2018).…”

“…Three phenolic acids and one flavonoid in PFLE were identified and quantified by HPLC-DAD and the results are summarized in Table 1. antidiabetic, and anti-inflammation (Bagdas et al, 2019;Natarajan et al, 2017;Srinivasulu et al, 2018).…”
