The present study focused on investigating the antioxidant, antiglycation activity, digestive enzymes inhibition, bioaccessibility and hypoglycemic effect of leaves extracts. The extracts deactivated the O•, ROO•, HO, HOCl reactive oxygen species. Coffee leaves showed strong inhibition of α-glucosidase (IC = 40.30 μg mL) greater than the isolated metabolites and acarbose. There was also inhibition of pancreatic lipase (IC = 56.43 μg mL) in addition to a hypoglycemic effect in zebrafish similar to acarbose and metformin. With the exception of rutin, all biocompounds were detected at all stages of digestion. Finally, these results suggest that leaf extracts possess antidiabetic and anti-obesity properties that can be attributed to the main metabolites and the synergistic action between them.Communicated by Ramaswamy H.

The present study explored the influence of submerged fermentation with different lactic acid bacteria (LAB) as a pre-treatment of moringa leaves before the extraction of phenolic compounds via sonotrode. The sonotrode extraction was optimized using a Box-Behnken design and the optimal conditions found were: 25 % ethanol, 5 min and 100 % amplitude. Folin-reacting substances and antioxidant activity were measured on hydroalcoholic extracts obtained from fermented moringa leaves and, individual phenolic compounds were determined by HPLC-ESI-TOF-MS for the first time.
