Abstract

Ionene has been identified as a thermal degradation product of β-carotene. The 5-percent yield of ionene represents the largest amount of any compound thus far identified from the degradation. Experimental evidence has been obtained indicating the presence of ionene in a marine sediment ment subjected to the same temperature used to degrade β-carotene.
