Effects of Hibiscus sabdariffa Linn. fruit extracts on a-glucosidase enzyme, glucose diffusion and wound healing activities
Journal Title: Asian Pacific Journal of Tropical Biomedicine - Year 2017, Vol 7, Issue 5
Abstract
Objective: To provide in vitro evidence for antidiabetic activity through potential inhibition of a-glucosidase enzyme, glucose diffusion and enhancement in the wound healing using methanolic extract and fractions from Hibiscus sabdariffa Linn. fruit. Methods: The inhibitory action of methanolic extract and fractions of such fruit on aglucosidase enzyme and glucose movement through in vitro assay assessment was reported. Their activities on wound healing were tested using the scratch assay. Results: Ethyl acetate fraction at 50 mg/mL concentration exhibited significant aglucosidase inhibition (95.79 mg/mL) with P < 0.05. At the same concentration, the methanolic extract as well as other fractions revealed lower a-glucosidase inhibition and higher glucose diffusion retardation across the dialysis tube than the control. Ethyl acetate and butanol fractions displayed notably higher glucose diffusion inhibitory activity of 5.21 mmol/L and 5.2 mmol/L, respectively as compared to methanolic extract and n-hexane fraction of 6.58 mmol/L and 6.49 mmol/L, respectively. Conversely, compared to other fractions the methanolic extract and ethyl acetate fraction manifested proliferative effect at the incubation time of 6 h during the wound healing study. Conclusions: It is established that methanolic extract and fractions from H. sabdariffa Linn. fruit can inhibit the a-glucosidase enzyme and glucose movement as well as influence the wound healing activity positively.
