Pistacia chinensis is a tree species with colorful leaves and great ornamental value. The mol. mechanism of its anthocyanin biosynthesis has been described from the transcriptional level. However, the type of anthocyanin cannot be obtained from the transcription level, which leads to the ambiguity of anthocyanin biosynthesis pathway. In this study, the pathway of anthocyanin biosynthesis was described from the metabolic level. A total of 27 anthocyanins, five procyanidins, and six flavones were identified and quantified in the red leaves of P. chinensis in autumn using UPLC-MS/MS. The dominant anthocyanin in P. chinensis leaves was cyanidin-3-O-galactoside, and its content was 121.10 ng/g, which accounted for 95.88% of the total anthocyanins. The content of methylated and acylated anthocyanins was very low, indicating that the anthocyanins in P. chinensis leaves were not prone to methylation and acylation. In addition, procyanidin B1, procyanidin B3, afzelin, and quercetin-3-O-glucoside were identified, and their contents were 12.00 ng/g, 12.84 ng/g, 5.44 ng/g, and 13.72 ng/g, resp. These metabolites were clearly mapped on the anthocyanin biosynthesis pathway. The anthocyanins biosynthesis in P. chinensis leaves is mainly via the dihydroquercetin pathway. Overall, these results enhanced our understanding of the biochem. basis of leaf coloration in autumn. 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: 29106-49-8Application of 29106-49-8).
(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. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Application of 29106-49-8
