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.
