Abstract
Aryl polyenes and heterocyclic polyenes with the same central C20 unit of β,β-carotene but different terminal groups were synthesised. Their free radical scavenging activity was measured by a 1,1-diphenyl-2-picrylhydrazinyl spectrophotometric method. The results indicated that all the new compounds have free radical scavenging activity.

Abstract
Citranaxanthin and its analogues were synthesised via a C5 unit elongation to substituted conjugated polyenes. Their free radical scavenging activity was measured by 1,1-diphenyl-2-picrylhydrazinyl spectrophotometric methods. Results indicated that the new compounds exhibited antioxidant activities. Three new analogues had stronger antioxidant activity than citranaxanthin.
