Extraction Condition Optimization, Quantitative Analysis, and Anti-AD Bioactivity Evaluation of Acorn Polyphenols from <i>Quercus variabilis, Quercus aliena,</i> and <i>Quercus dentata</i>.

ABSTRACT: In the present study, Quercus variabilis (Q. variabilis), Quercus aliena (Q. aliena), and Quercus dentata (Q. dentata) acorn kernels were taken as the research objects, and the free polyphenols and bound polyphenols in acorn kernels were extracted using improved ultrasound-assisted ethanolic and alkaline extraction methods, after which the contents of gallic acid, quercetin, azelaic acid, ellagic acid, and ferulic acid were quantified by LC-MC/MS. The results demonstrated that Q. variabilis and Q. aliena acorns were suitable as raw materials to extract ellagic acid, the contents of ferulic acid and bound gallic acid in them were different, and Q. aliena acorns were more suitable for the research of gallic acid, but not for azelaic acid.
