A triterpenoid, betulin together with two steroids, b-sitostenone and pregnenolone were isolated from dichloromethane crude extract in the twigs of Millettia utilis Dunn. The structures of all isolated compounds were elucidated by basic NMR spectroscopy and compared with previous literature. All compounds were tested for their antioxidant activities. Betulin revealed moderate activity against ABTS assay.
