Antiglycemic Effect of Water Extractable Arabinoxylan from Wheat Aleurone and Bran

Table 2

Effect of feruloylated arabinoxylan on intestinal α-glucosidase when sucrose or maltose was used as substrate.

	IC50 (mg/mL)
	Maltose	Sucrose
WA-f50	4.88 ± 0.30 (0.49)
WA-f75	10.14 ± 0.56 (1.01)
WB-f50	5.73 ± 0.19 (0.57)
WB-f75	8.15 ± 0.46 (0.81)
Acarbose	0.005 ± 0.00 (~0.0005)	0.003 ± 0.00

Values presented as mean ± standard deviation (). Data in the same column with the same superscript are not significantly different at . Data in parenthesis are IC50 values in % w/v. IC50 value is the sample concentration resulting in 50% inhibition of α-glucosidase activity. WA-f₅₀ and WA-f₇₅: water-extractable fractions from WA obtained at 50 and 75% ammonium sulphate saturation, respectively. WB-f₅₀ and WB-f₇₅: water-extractable from WB obtained at 50 and 75% ammonium sulphate saturation, respectively.
