Inhibitory effect of voglibose and gymnemic acid on maltose absorption in vivo

Figure 1 The inhibitory effects of GA (0. 5 g/L), voglibose (V, 2 μmol/L) and the combination (GA + V) on 10 mmol/L maltose absorption. The maltose contained in the fluid at perfusion starting point was taken as 100%. Each bar is expressed as the Mean ± SE. (^aP < 0.05, ^bP < 0.01)

Figure 2 Alteration of maltose absorption following application with GA and voglibose. Each point is shown as the maltose absorption during 60 min perfusion of 10 mmol/L maltose following treatment with GA and/or voglibose, except the points of “CON” or “GA/V” which are shown as the absorption during first 1 h perfusion with or without GA and voglibose. Others are the same as in Figure 1.

Figure 3 Hydrolytic rates of maltose in each group during R2 in Figure 2. The conditions are the same as in Figure 2.

Figure 4 Total maltose absorption in 3 times perfusion during 4 h. The absolute amounts of maltose absorbed during three perfusions (T, R1 and R2) are compared with each other.
