The present investigation was aimed to utilize lignocellulosic agro-residues and compare the extraction of polyphenols utilizing lignocellulolytic enzymes secreted by Sphingobacterium sp. ksn and with that of the solvents (ethanol, methanol) affiliated methods. The maximum amount of polyphenols, flavonoids and tannins were 94.29, 11.36, and 79.21 g 100 g-1 respectively, found in the extracts obtained by enzymes affiliated extraction of coffee cherry husk (CCH). The phenolics namely, gallic acid, caffeic acid, coumaric acid, 1-hydroxybenzoic acid, 2,5-dihydroxybenzoic acid, p-hydroxybenzaldehyde were commonly found whereas syringic acid, quercetin, kaempferol, and epicatechin were hardly found in the extracts of agro-residues. The extracts of CCH shown maximum antioxidant properties for DPPH, ABTS, and FRAP. The present study reports that the affiliation of enzymes for the extraction of polyphenols from agro-residues is more efficient than that of the solvents affiliation and CCH as the good source of polyphenols.
