Abstract: Antioxidative activity of several spice oil (laed oil as substrate) was investigated by oven storage.Lisea cubeba oil had a very atrong antioxidation, it was oveer two times more effective than butyl hydroxy anisol (BHA), and more effective than ginger oil, mandarin oil, cinnamon oil. The ground residues of litseacubeba bark after oil distillation were extracted with several different solvents, their extractives all had antioxidation to a certain extent, the extractives were less effective than litsea cubeba oil. Chloroform extractives were the most effective on antioxidation of all the extractives, its strength was about 75% that of BHA.Kegwords:Litsea cubeba oil Residue Antioxidation
