Abstract

Kecombrang (Etlingera elatior) is a zingiberaceae plant, which has long been known as one of the vegetables and used by the community as a nutritious food to preserve food because of the active substances contained in it, such as saponins, flavanoids, and polyphenols. In this research, antioxidants activity of kecombrang flower extract was measured by using 1,1-diphenyl-2-picrilhidrazil (DPPH) method. The kecombrang flower extract has several secondary metabolite compounds, such as alkaloid, terpenoid, steroid, phenolic, flavonoid, tanin with very small antioxidant activity, which is showed by inhibition percentage. As many as 100 ppm concentration of the kecombrang flower extract, ie, methanol extract 3.21%, ethyl acetate extract 5.08 %, and n-hexane extract 30.29%. So it can be concluded that the antioxidant activity of flower kecombrang (Etlingera elatior) is less active.
