CAROTA-1,4-DIENALDEHYDE, A SESQUITERPENE FROM ROSA RUGOSA

Article abstract of DOI:10.1016/0031-9422(90)80035-F

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.
