Antioxidant and α-Glucosidase Inhibitory Activities Guided Isolation and Identification of Components from Mango Seed Kernel

Figure 3

The binding modes and 2D diagram of α-glucosidase inhibition by acarbose (a, b), 1, 2, 3, 4, 6-Penta-O-galloyl-β-D-glucoside (1) (c, d) and 1, 2, 3, 4, 6-Penta-O-galloyl-α-D-glucoside (2) (e, f). The small molecules were shown in green sticks, while the hydrogen bonds were shown in yellow sticks (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.).
