Nurman, Salfauqi published the artcileOptimization and characterization of n-hexane extracts of arabica coffee ground (Coffea arabica L.) from Gayo Plateau as source of natural antioxidant, Application In Synthesis of 110-42-9, the main research area is Coffea hexane extract natural antioxidant activitiy.
Arabica coffee is a major commodity crop in the Gayo Plateau, Aceh Province. Utilization of coffee in the area only as a raw material for making coffee drinks and produce waste that is not utilized. The aim of this study is optimization and characterization of n-hexane extract of Arabica Gayo coffee ground (Coffea arabica L.) as a source of natural antioxidant. The extraction process used soxhlet method with n-hexane solvent. Characterization of arabica coffee ground oil consist ofanal. of functional group using FTIR, component anal. using GC-MS and antioxidant anal. using DPPH method. The optimum time of the soxhletprocess of Arabica coffee is 180 min with rendement of 9,54%, anal. of functional group shows CH2 asym. stretch at 2922 cm-1, CH2 sym. stretch at 2853 cm-1, C=O asym. stretch at 1741 cm-1, CH2 bending at 1458 cm-1, C-CH3 vibration at 1159 cm-1 and CH vibration at 718 cm-1. The main component of Arabica Gayo coffee ground oil is 1,2-benzenedicarboxylic acid, bis(2-ethylhexyl) ester with an area of 18.09%, antioxidant activitiy of Arabica Gayo coffee ground oil is very weak with IC50 value = 1222,31 ppm.
