Recently, there has been increasing interest in Ficus deltoidea (Moracea) due to its chemical composition and the potential health benefits. The leaves of the plant have been suggested to have potential antidiabetic effects. Inhibition of carbohydrate-hydrolysing enzymes, such as α-glucosidase and α-amylase is one of the therapeutic approaches to control postprandial hyperglycemia. In this study, enzymes inhibitory effect and antioxidant properties of different fractions of methanolic extract obtained from F. deltoidea leaves was evaluated. Further, the possible relationship between pharmacological properties and phytochemical content of fractions was investigated. The n-butanol fraction showed significant α-glucosidase and α-amylase inhibitory effects (IC50 values 15.1 and 39.42 μg/ml, respectively) along with the remarkable antioxidant activity when compared to the other fractions. High performance liquid chromatography (HPLC) chemical profiling of the n-butanol fraction revealed that the contents of isovitexin (24.63 mg/g) and vitexin (8.3 mg/g) were found to be significantly higher than the other fractions. These results indicate that F. deltoidea could be the potential source of promising anti-diabetic drug.
