Abstract

The extraction of bioactive compounds from fruits of green coffee (Coffea canephora) was performed using solid-liquid percolation process and hydroethanolic solvent, by way of a 2(2)central composite rotatable design (CCRD) and response surface methodology (RSM). Bioactive contents and yield of process were the dependent variables assessed. The process yield was 25 +/- 1.2%, 5-CQA, caffeine and trigonelline contents were 9751 +/- 274, 6822 +/- 127, 2664 +/- 118 mg/100 g, respectively. The bioactive contents and reducing capacity in GCFE remained stable for 180 days at 40 degrees C, which suggests its potential application in the pharmaceutical and food industries as an ingredient.
