The hydro-alcoholic extract of Withania coagulans fruits was investigated for preliminary phytochemical screening and characterized by high-performance thin-layer chromatography. Column chromatography of the hydro-alcoholic extract of W. coagulans eluted with four different combinations of ethyl acetate and methanol yielded four fractions (WCF01, WCF02, WCF03, and WCF04). One of these fractions, WCF02, significantly (P less then 0.05) inhibited in vitro α-amylase and α-glucosidase activity with IC50 values of 104.71 μg/mL and 70.79 μg/
