	10	8.67
Nopal water extract	100	53.23	67.33 ± 6.47
	50	47.22
	25	44.65
	10	28.89
	5	19.02
	2.5	5.12
Acarbose(2)	100	68.39	38.05 ± 2.80
	50	59.41
	25	49.34
	10	39.32
	5	34.41
	2.5	16.46

 ⁽¹⁾The IC₅₀ value was defined as the half-maximal inhibitory concentration and mean of 3 duplication analyses of each sample.

 ⁽²⁾Acarbose was positive control.
