Common Name | Angelic acid |
---|
Description | Angelic acid is found in fats and oils. Angelic acid is a constituent of Angelica archangelica (angelica) Angelic acid has a double bond between the second and third carbons of the chain. Together with tiglic acid form a pair of cis-trans isomers. Angelic acid is a volatile body, of biting acid taste and pungent sour odour. It crystallizes in colorless monoclinic prisms. Angelic acid was formerly used therapeutically as a sedative. Angelic acid is a monocarboxylic unsaturated organic acid. It is found in garden angelica (Angelica archangelica), Umbelliferae, and many other plants. It was also isolated from the defensive secretion of certain carabid beetles |
