Abstract

Phenolics were extracted from Indian oak (Quercus sp.), teak (Tectona grandis), red cedar (Cedrella toona) and sandal (Santanum album) by ethanol. Amounts of phenolics extracted in relation to wood:ethanol ratio, concn. of solvent, and time of contact for extraction of phenolics were determined. Extracted phenolics were segregated into flavonoids and non-flavanoids as well as into fractions soluble and insoluble in the solvents chloroform, ethyl acetate and amyl alcohol. The fractionated phenolics were estimated after removal of the solvents. Tables of results are given. Studies on organoleptic evaluation of young brandy on addition of these fractions of phenolics (free from solvents) indicated that some combinations of fractions reduce the harshness of the product.
