Abstract

Green tea processing creates a hot acidic environment that facilitates reactions between catechins and hydroxycinnamic acids (HCAs), generating new catechins. Accordingly, we developed a one-pot method incorporating a Michael addition reaction to synthesize 13 phenylpropanoid-substituted ester-type catechins (PSECs), whose contents exhibit seasonal changes in tea leaves similar to those observed for common catechins. These PSECs showed antiaging effects in
