Abstract

The title octa-deca-trienoic acid derivative, C(18)H(26)O(4), was isolated from Silene maritima With. (Caryophyllaceae), the first time this natural compound has been found in the Caryophyllales order. This fatty acid has an 18-carbon backbone with three double bonds on trans (E) conformation and two carbonyl. In the crystal, molecules are linked via pairs of O-H⋯O hydrogen bonds, forming inversion dimers.
