The purpose of this study was to investigate the antidiabetic effect of phytocompounds from Swietenia macrophylla seed using preliminary phytochemical screening, invitro antioxidant activity and molecular docking studies. The powdered seed extract of Swietenia macrophylla was to investigate the phytochemical screening exhibited the presence of alkaloid, phenols, tannins, flavonoids, terpenoids, steroids, carbohydrates, amino acids and proteins as major active constituents. The antioxidant activity of Swietenia macrophylla seed was evaluated by DPPH free radical scavenging assay. Rutin was used as a reference compound. The Swietenia macrophylla seed exhibited 56.0471% of free radical scavenging activity as compared with rutin. The molecular docking studies performed by using molecular docking server online respectively in which the antidiabetic target namely glutamine:fructose-6-phosphate amidotransferase (GFAT) (PDB id: 2ZJ3) have a potential interaction with swietenine, swietenolide, β-sitosterol, and fucosterol. In this study, the protein glutamine:fructose-6-phosphate amidotransferase (GFAT) was used from its structure perspectives. Its primary and secondary structures were evaluated using online tools. Its role in antidiabetic was assessed by molecular docking the compounds present in the seed extract of Swietenia macrophylla assayed by GC-MS analysis. This in-silico study demonstrates the interactions of active components of Swietenia macrophylla against Type I and Type II diabetes.
