Tagetes lucida is widely used in traditional Mexican medicine for several disorders, including those associated with inflammation. In this work, fifteen compounds were identified (1-15) from T. lucida. Some of these compounds (1-8, 10, 12-14) were detected for the first time in the plant, and quercetagetin 7-O-β-(6''-Protocatecoyl) glucopyranoside (13) has been identified for any plant species. The inflammation inhibition effects of these compounds were as follows: Amix (1-2) > 10 > 12a > 13 > 14a > Bmix (3-9) > 12; 12 and 13 showed a dose-response behavior. The mixture of 14 and 15 was not active. This work contributes to the knowledge of the anti-inflammatory capacity of T. lucida and the chemical identity of their bioactive compounds.
