Chemical constituents from Mesua lepidota T. Anderson and their chemotaxonomic significance

The phytochemical investigation on Mesua lepidota T. Anderson led to the identification of eight Mammea coumarins lepidotols A-B (1-2), lepidotol E (3), lepidotins A-C (4-6), mammea A/BB cyclo F (7), and ochrocarpin E (8)], five triterpenes friedelin (9), friedelinol (10), betulinic acid (11), gluti...
