Abstract

This research to determine the effect of extraction method on free-radical scavengers on shell
of yaki pinang fruit. Yaki betel nut shell extraction is done by the method of maceration,
percolation and soxhletasi. Activity test done with free-radical scavengers DPPH. Result
method were analyzed by using UV-Vis spectrophotometer. Results of research on method
soxhletasi have free-radical scavengers that activity is quite high in concentrations of 50
mg/L (85,16%) and 100 mg/L (92,31%) compared to the maceration extraction method that
has a value of percent inhibition of 74,61% at a concentration 50 mg/L and 81,32% at a
concentration of 100 mg/L and percolation to the value of 14,28% at a concertration of 50
mg/L, and 17,17% at a concentration of 100 mg/L using the DPPH test.
Key words : pinang yaki (Areca vestiaria Giseke, antioxidant, DPPH
