abstract={Secondary metabolites of medicinal plants constitute a real alternative treatment for diabetes mellitus. They are also sources of natural compounds that could lead to the discovery of new drugs. In this study, the anti-amylase and antioxidant activities of alkaloids and flavonoids extracted from <i>Mitracarpus hirtus</i> leaves were evaluated. DPPH radical and DNS inhibition methods were used for antioxidant activity and anti ¦Á-amylase activity, respectively. The results obtained showed that di- and tri-glycoside flavonoids and monoglycosides are the most present with contents of 796 and 522 mg RQE/gES while alkaloids are present at 203 mg RQQ/gES. The DPPH radical inhibitory activity test gives IC<SUB>50</SUB> of 187.99; 236 ug/ml for the di and tri glycosides and monoglycosides flavonoids respectively. Alkaloids show IC<SUB>50</SUB> of 815ug/ml and ascorbic acid used as reference has IC<SUB>50</SUB> of 110 ug/ml. The result of the anti ¦Á-amylase activity shows that the monoglycoside flavonoids are more active with an IC<SUB>50</SUB> of 74 ug/ml while the alkaloids have an IC<SUB>50</SUB> of 228 ug/ml. We note that in all the studied parameters, flavonoids are more active than alkaloids. However, the activity of flavonoids is not polarity dependent. The fractions rich in flavonoid mono, di and tri glycosides present rather interesting activities and deserve to be tested <i>in vivo</i> in order to propose them as an alternative treatment for diabetes mellitus.},
