	100	18.96 ± 6.20
	200	34.04 ± 10.47
	300	48.36 ± 6.44
Acarbose	25	33.29 ± 7,62	69.47 ± 5.27
	50	49.49 ± 3.98
	100	55.90 ± 8.01
	200	61.55 ± 6.79
	300	70.60 ± 5.14

Each result represents the mean ± standard derivation (n = 3). Data analysis was performed by one-way ANOVA followed by Tukey’s post hoc test. IC₅₀: concentration of the extract necessary to inhibit the activity of the enzyme by 50%. RSE: Rytigynia senegalensis extract.
