Anti-oxidative substances from chilli seed were extracted with different solvents.The anti-oxidative activities of the extracts from chilli seed were study by Na 2S 2O 5-I 2 titration method. It was found that all extractive of chilli seed have strong anti-oxidative effects for lard. The effects are different in different solvents and different species chilli. The anti-oxidative effects decreased in the following order: methanol extracts from de-fatted chilli seed>methanol extracts>water extracts from de-fatted chilli seed>petrol extracts. It was also found that the anti-oxidative effect of chilli seed from HuaXi is better than that from ZunYi.
