Extracts of Eucalyptus alba Promote Diabetic Wound Healing by Inhibiting α-Glucosidase and Stimulating Cell Proliferation

Figure 5

Wound healing activity of ethanol-, methanol-, and acetone-based extracts prepared from E. alba leaves dried at 10°C, 30°C, 50°C, and 100°C at 0.1 mg/mL concentration after 16 hours of incubation. (a–d) are treatment with ethanol-based extracts, (e–h) represent treatment with methanol-based extracts, and (i–l) are treatments with acetone-based extracts at 0.1 mg/mL. Platelet-derived growth factor and phosphate-buffered saline were used as positive and negative control represented by (m) and (n), respectively. Scratch area immediately after it is produced is represented by (o).
