Chisocheton balansae C.DC., is one of the Meliaceae family plants which endemic from Soputan Mountain, North Sulawesi, Indonesia. This study was aimed to determine chemical structure flavan-3-ol compounds ethyl acetate extract C. C.DC stembark. Dried powder stem bark extracted consecutively with n-hexane, acetate, and methanol solvents. Four compounds, named catechin (1), epicatechin (2), epiga...
Litchi (Litchi chinensis Sonn.) fruit is known for its rich source of phenolics. Litchi pericarp contains high levels of epicatechin that may form oligomers of various lengths. Except for several A or B type epicatechin dimers, other soluble oligomers have rarely been identified in the pericarp. Here, bioassay-guided column fractionation was applied to isolate bioactive phenolics from aqueous p...
Dark chocolate (DC) may be cardioprotective by antioxidant properties of flavonoids. We investigated the effect of DC (860 mg polyphenols, of which 58 mg epicatechin) compared with white chocolate (WC; 5 mg polyphenols, undetectable epicatechin) on plasma epicatechin levels, mononuclear blood cells (MNBC) DNA damage and plasma total antioxidant activity (TAA). Twenty healthy subjects followed a...
Bioconversion of (-)-epicatechin (-EC), (+)-epicatechin (+EC), (-)-catechin (-C), and (+)-catechin (+C) by (-)-epigallocatechin (-EGC)-metabolizing bacteria, Adlercreutzia equolifaciens MT4s-5, Eggerthella lenta JCM 9979, and Flavonifractor plautii MT42, was investigated. A. equolifaciens MT4s-5 could catalyze C ring cleavage to form (2S)-1-(3,4-dihydroxyphenyl)-3-(2,4,6-trihydroxyphenyl)propan...
The epicatechin (EC) thio derivatives 4β-(S-cysteinyl)-epicatechin (Cys-EC) and 4β-(S-cysteaminyl)-epicatechin (Cya-EC) are compounds that may provide protection from oxidation via mechanisms involving either the flavonoid moiety or the nonphenolic cysteine or cysteamine part of the molecule. Because the metabolically modified molecules may be the actual active species, we estimated the absorpt...
Tea (Camellia sinensis) is rich in specialized metabolites, especially polyphenolic proanthocyanidins (PAs) and their precursors. To better understand the PA pathway in tea, we generated a complementary DNA library from leaf tissue of the blister blightresistant tea cultivar TRI2043 and functionally characterized key enzymes responsible for the biosynthesis of PA precursors. Structural genes en...
Epigallocatechin-3-gallate (EGCG), a dietary polyphenol (flavanol) from green tea, possesses leishmanicidal and antitrypanosomal activity. Mitochondrial damage was observed in Leishmania treated with EGCG, and it contributed to the lethal effect. However, the molecular target has not been defined. In this study, EGCG, (+)-catechin and (-)-epicatechin were tested against recombinant arginase fro...
While polyphenolic compounds have many health benefits, the potential development of polyphenols for the prevention/treatment of neurological disorders is largely hindered by their complexity as well as by limited knowledge regarding their bioavailability, metabolism, and bioactivity, especially in the brain. We recently demonstrated that dietary supplementation with a specific grape-derived po...
