Determination of antioxidation activities of Sarawak’s traditional herb kacangma leonurus sibiricus

Antioxidant activities of ethanolic and aqueous extract from kacangma (Leonurus sibiricus) were determined by using three model systems. Based on the antioxidant activity range, ethanolic extract of dried kacangma was high in oxidation of linoleic acid lipid system (LP) 71.6%, moderate in xanthine o...
