PROPERTIES OF BAJAKAH TAMPALA WOOD (Spatholobus littoralis Hassk) ETHANOL EXTRACT AGAINST α-AMYLASE INHIBITION AS AN ANTIDIABETIC COMPOUND CANDIDATE AND ITS FORTIFICATION IN KAPOK HONEY

Bajakah Tampala extracted with ethanol was indicated to contain phenols and flavonoids. So far, the Bajakah Tampala wood ethanol extract (BTWEE) has only been analyzed for its antioxidant activity. Flavonoids not only act as antioxidants but also play a role in inhibiting α-amylase which is related to antidiabetic properties. The BTWEE has never been used as a fortificant in honey. This study aims to determine the levels of phenols, flavonoids, antioxidant activity, and α-amylase inhibitory activity of BTWEE at various solvent concentrations (70%, 80%, 90% of ethanol) and to investigate the effect of adding BTWEE to Kapok honey on its bioactivity. This study was conducted using post test only group design that was applied to 1% fortification of Kapok honey into the BTWEE. Parameters tested in the study were total phenolic content (TPC), total flavonoid content (TFC), antioxidant activity (DPPH scavenging activity), and % inhibition of α-amylase. The result showed the higher the ethanol concentration, the lower TPC, TFC, antioxidant activity and α-amylase inhibition. The addition of 1% BTWEE increased TPC, TFC, and % inhibition of α-amylase of Kapok honey. The BTWEE has the potential as an antidiabetic compound candidate and Kapok honey with BTWEE has the potential as functional honey.
