IDENTIFICATION OF (Z,Z,Z)-5,9,12-OCTADECATRIENOIC ACID AND (Z,Z)-5,9-OCTADECADIENOIC ACID AS POSSIBLE BIOSYNTHETIC PRECURSORS OF NEW HYDROCARBONS (Z,Z,Z)-4,8,11-HEPTADECATRIENE AND (Z,Z)-4,8-HEPTADECADIENE FOUND IN THE ASTIGMATID MITE, TORTONIA SP, Applied Entomology and Zoology, 30(3), 1995, pp. 433-441
(Z,Z,Z)-5,9,12-Octadecatrienoic acid and (Z,Z)-5,9-octadecadienoic aci
d were isolated as components of body lipid from an unidentified speci
es of the genus 'Tortonia [Astigmata:Suidasiidae]. The chemical struct
ures were elucidated either by partial hydrogenation and subsequent GC
/MS analysis of their dimethyldisulfide (DMDS) derivatives, or by GC/M
S analysis of their DMDS derivatives. Both are new fatty acids constit
uting natural products obtained from mites and are possible biosynthet
ic precursors of the new hydrocarbons (Z,Z,Z)-4,8,11-heptadecacriene a
nd (Z,Z)-4,8-heptadecadiene found in the same species.
