And the article was included in Journal of Food Composition and Analysis in 2022.Name: (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol The following contents are mentioned in the article:
Identifying the discrepancies between cultivated tea and its wild relatives, especially in terms of their chem. compositions, is important in exploitation of specific germplasms. This study systematically investigated the phylogenetic relationships, morphol. traits, and metabolite profiles of 27 typical tea accessions. Results showed that 84,797 high-quality single nucleotide polymorphisms classified the sampled tea accessions into two groups, namely, Camellia sinensis (L.) O. Kuntze (CS) and its close relatives (CR), most of which were supported by morphol. evidence. Targeted metabolomic analyses absolutely quantified 51 characteristic metabolites. Among these metabolites, two tetragalloyled hydrolyzable tannins and four flavonol trisaccharide glycosides accumulated in low amounts in CS and CR, resp. Furthermore, the notable discrepancy in chem. composition was validated by the metabolite profiles of 114 tea accessions. Overall, this study showed the diversification of Sect. Thea plants regarding the genetic, morphol., and chem. characteristics, leading to a better understanding of wild tea plants. This study involved multiple reactions and reactants, such as (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol (cas: 29106-49-8Name: (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol).
(2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol (cas: 29106-49-8) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Name: (2R,2’R,3R,3’R,4R)-2,2′-Bis(3,4-dihydroxyphenyl)-[4,8′-bichromane]-3,3′,5,5′,7,7′-hexaol
