Abstract

This study was an initial step to evaluate grape seeds from the waste products of the food industry as nutraceutical materials. Grape seeds of Campbell Early cultivar (Vitis labrusca×Vitisvinifera) were dried and pulverized followed by extraction with absolute methanol. The total phenolic content of grape seed extract (GSE) was 80.82mg gallic acid equivalent/g seed. The amount of total flavonoids was 27.04mg (+)-catechin equivalents/g of grape seed. GSEs exhibited antioxidant activities of 60.13mg ascorbic acid equivalent/g seed and 209.45mg Trolox equivalent/g seed for 1,1-diphenyl-2-picrylhydrazyl and 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid), respectively. GSE inhibited lipid accumulation of C3H10T1/2 and 3T3-L1 cells in a dose-dependent manner. Inhibition was also associated with reduced expression of PPARγ, the master regulator of adipocyte differentiation. Further study is needed to identify specific molecules which attribute bioactivities of GSE.
