SESQUITERPENES ALKALOIDS FROM Maytenus distichophylla (CELASTRACEAE). The phytochemical study of the roots of Maytenus distichophylla Mart. ex Reissek (Celastraceae), resulted in the isolation of the seven sesquiterpenes pyridine alkaloids euojaponine F (1), euojaponine K (2), ebinifoline W-I (3), wilforine (4), maiteine (5), euojaponine A (6) and ebinifoline E-II (7). The structures of compounds were established using spectroscopic techniques such as 1D and 2D NMR. All compounds were subjected to an in silico study through of a predictive model and then submitted to in vitro testing against S. epidermidis, P. aeruginosa, C. parapsilosis and C. albicans for evaluation of their antimicrobial activity. The compounds tested showed bacterial and fungal growth inhibition with MIC values 1024 and 256 µg mL-1, respectively.
