Abstract
Smoke produced with sawdust of Quereus Glandulifera was passed successively through a silicagel tube and a bottle containing soy-bean oil.
After that, materials adsorbed on the silicagel were extracted with methanol, and the solvent was distilled off.
The greatest antioxidint activity was recognized with this methanol extracted fraction of the smoke, and, by the paper chromatographic analysis, naphthol, isoamylgallate, hydroquinone, propylgallate, and butyl-hydroxytoluene ware detected in this fraction.
