The antioxidative activities of rape, coriander, leeks, celery, green bean sprouts, fructus lycii from Ningxia and Vitamin C were analyzed in thi s study. The results showed that inhibition rates of TBAS formation (TBASI) of corian der, leeks, green bean sprouts, fructus lycii and Vitamin C were 85 3%,71 7%,77 6%,94 6% and 90 3% respectively,which were higher than that of rape (65 1%) and cemery (56 7%) before boiling. The TBASI was enhanced with the increa se of the amount of sample input. The antioxidative activities of celery, rape, leeks and Vitamin C were 22 3%,34 5%,35 5% and 5 1% respectively,which were significant decreased after boiling,green sprouts,coriander and frutus lycii were 58 3%,63 2% and 74 9% respectively, which were not significant decrea sed after boiling.The results suggested that elements of heart-resisted antioxi dative may exist in these five types vegetables and fructus lycii.
