A new sesquiterpene, (7R,10R)-carota-1,4-dienaldehyde was identified in Rosa rugosa leaves, and its structure elucidated by spectroscopic and chemical methods.The new compound was markedly unstable under air exposure to give several oxidized derivatives, in which rugosal A was found as the main product due to the 1,4-diene structure.The corresponding carboxylic acid, carota-1,4-dienoic acid was found in the leaves.

In the autoxidation of (7R,10R)-carota-1,4-dien-14-al 1, which is a precursor of an antifungal compound rugosal A 2, in Rosa rugosa leaves, an intermediate possessing a 1,5-endoperoxy-2-hydroperoxy system 4 was isolated as a major product.The structures of compound 4 and other by-products including rugosal A 2 and rugosic acid A 3 were determined.These autoxidation products indicated the conversion pathway of compound 1 into rugosal A 2, similar to the radical reaction pathway in the autoxidation of polyunsaturated fatty acids.
