3.1. Extraction
Table 1 shows the percentage yield of potato peel extract obtained after refluxing ground potato peels with different organic solvents, i.e. ethanol, methanol,acetone, hexane, diethylether and petroleum ether. About 5.88–21.00% potato peel extract was obtained with these six different organic solvents. However, the maximum amount of potato peels extract (21.00%) was obtained with petroleum ether. followed by diethyl ether (15.25%) and methanol (14.75%). About 12 different phenolic antioxidant compounds have been reported in the non-volatile fraction of petroleum ether extract of
potato peels by Onyenecho and Hettiarrachchy (1993). Therefore, antioxidant activity of the extract of highest
yield (petroleum ether) was tested in refined soy bean oil at 25 and 45 C during 60 days, storage
