In vitro and in silico Screening of Bioactive Compounds from Jasminum subtriplinerve Blume as α-glucosidase Inhibitor

Abstract

The leaves of Jasminum subtriplinerve Blume were extracted by cold maceration with ethanol 70 % and subsequently fractionated with n-hexane, ethyl acetate (EtOAc), and n-butanol (n-BuOH) solvents. The extract and fractions were evaluated α-glucosidase inhibitory activities in vitro. The results have shown that n-hexane and EtOAc fractions had strong α-glucosidase inhibitory effects with IC₅₀ values of 7.27 ± 0.71 mg/mL and 7.42 ± 0.95 mg/mL, respectively. The total extract, the n-BuOH fraction, and the aqueous fraction did not show inhibitory effects on the enzyme α-glucosidase. The molecular docking results revealed that rutin, isoverbascoside, astragalin, isoquercitrin, verbascoside, stigmasterol, nicotiflorin, and chevangin B might play an important role in the biological effect of this medicinal plant. Among these compounds, astragalin, isoquercitrin, verbascoside, and stigmasterol may be developed as drugs. Our findings suggested that leaves of Jasminum subtriplinerve Blume will be the potent resource of natural α-glucosidase inhibitors.

Keywords: α- glucosidase, diabetes, Jasminum subtriplinerve, molecular docking.
