Abstract:

This study aims to examine the activity of the antioxidant activity of ethanol extract of lontar fruit peel (Borassus flabellifer l.) and ginger bud (Etlingera elatior (Jack.) R.M. SM) by using the ferric reducing antioxidant power method. Extraction was carried out by maceration method using 70% ethanol. The extracts were analyzed quantitatively with the addition of FRAP reagents measured by UV-Vis spectrophotometer analyzed at a wavelength of 752.29 nm in the ginger bud fruit peel and 727.05 nm for palm fruit skin using a quartetine as a comparison. Based on data analysis, the average value of the three antioxidant activity of the replication was 2.482 mg QE / g Extract on the skin of ginger bud fruit and 99.846 mgQE / g extract for lontar fruit skin. The conclusion shows that both the ginger bud fruit skin and lontar fruit skin have antioxidant activity.
