Identification of the new hydrocarbon (Z,Z)-1,6,9-heptadecatriene as the secretory component of Caloglyphus polyphyllae (Astigmata: Acaridae)

A new heptadecatriene was isolated from the acarid mite, Caloglyphus polyphyllae, as the major characteristic component which could be used to identify the species chemo-taxonomically. Its structure was elucidated as 1,6,9-heptadecatriene by partial hydrogenation and a subsequent GC/MS analysis of the dimethyldisulfide derivative, together with evidence of the terminal vinyl group and Z-configuration of double bonds that was provided by GC-FT/IR and NMR. The triene was identified as (Z,Z)-1,6,9-heptadecatriene by its synthesis and is revealed to be a new compound as a natural product.
