Lavandula viridis L’Hér is an aromatic shrub with relevant biological activities associated to the presence ofphenolic compounds. However, these compounds must be bioavailable to exert their biological function.Therefore, in this study, we investigated the influence of the L. viridis extract matrices on the digestion ofthe main component rosmarinic acid and their antioxidant and anti-cholinesterase activities after in vitrogastrointestinal digestion. Overall, the antioxidant and anti-cholinesterase activities were assured afterin vitro gastrointestinal processes and we observed that the L. viridis extract matrices have an importantrole in the bioactive effects of their main compound, rosmarinic acid. The L. viridis extracts and rosmarinicacid did not show any toxic effect on colon adenocarcinoma Caco-2 cell viability. Finally, the compoundsfrom L. viridis extracts were not metabolized by Caco-2 cells and were not able to permeate into them.
