Inhibition of Intestinal α-Glucosidase and Glucose Absorption by Feruloylated Arabinoxylan Mono- and Oligosaccharides from Corn Bran and Wheat Aleurone
Figure 2
Negative ion mass spectra of feruloyl mono/oligosaccharide arabinoxylans [M-H]− from corn bran (a) and wheat aleurone (b and c). Compounds eluting at 26.12 and 27.57 minutes in corn bran UV spectra had the same molecular weight [M-H]− of 325 (a). Also compounds eluting at 13.28 minutes in wheat aleurone UV spectra had = 721 (b) whereas those at 14.57, 15.78, 16.92, and 17.63 minutes had the same = 853 (c).
