“…Structurally, it is an ester of caffeic acid (CA) (Scheme 1), with 3,4-dihydroxyphenyl lactic acid (DHPLA), thus having two electroactive catechol moieties, which are able to neutralize free radicals by an electron/proton donor mechanism. Furthermore, the hydroxyl and carboxyl oxygen confer good metal-chelating properties to RA [3,4]. VB, also named as acteoside, is another hydroxycinnamic ester derivative widely distributed in plants, including diverse medicinal herbs, such as echinacea, lemon verbena (Aloysia triphylla), mullein (Verbascum Thapsus), Indian warrior (Pedicularis densiflora), savannah tea (Lippia multiflora) [8,[16][17][18][19], and olive fruits [5,9,20,21].…”
