Abstract: The paper first analyzed the carotenoids in the red yolks of duck, and probed into the inhibition of the carotenoidson S180 tumour. Several carotenoids, for example, astaxanthin, etc, were found in the red yolk. The carotenoids had a marked inhibitionon MDA and on the proliferation of S180 tumour, and showed a relationship between dosage and effect. The inhibition rates of low,middle and high dosage groups were 23.2%, 35.7% and 42.9% respectively. The carotenoias had a remarkable improving effect onthe internal organs index of tumour carried rats. The serum MDA content of tumour carried rats was markedly depressed.

Key words: red yolk duck egg, carotenoids, anti-oxidation, anti-tumour
