The effect of thermal pretreatments on the distribution of free (FP) and bound phenolic (BP) in virgin C. oleifera seed oil, via mixed materials by hot air at 90-150°C for 0-120 min before pressing, was investigated, using ultra-performance-liquid-chromatog. tandem quadrupole time-of-flight mass-spectrometry (UPLC Q-TOF MS). In total, 162 components were tentatively identified, consisting of 76 phenolic acids, 33 flavonols, 22 flavones, 12 flavan-3-ols, 11 flavanones, 5 stilbenes and 3 others. The contents of total phenolic profiles ranged from 84.8 to 154.5 mg/kg, occupied 43.7-57.8%, 16.5-36.7% and 16.0-26.4% in FP, base-bound (BP-B) and acid-bound phenolic (BP-A), resp. Gallic acid derivatives of phenolic acids, kaempferol derivatives of flavonols, and dimer of flavan-3-ols were the chief phenolic profiles, but presented dissimilarly in phenolic forms. The PCA suggested in comparison with the control, the distribution of BP-B had a remarkable variation as soon as the heating, and different behaviors occurred at 90°C after 60 min and 150°C after 60 min in BP-A and FP, resp. Similarly, prominent differences were discovered for the main contributors among phenolic forms. This novel perspective could be of significance to explore the proper pretreatment processing of virgin C. oleifera seed before oil production 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: 29106-49-8Formula: C30H26O12).
(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. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Formula: C30H26O12
