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.
一种新的十七碳三烯化合物从粉螨Caloglyphus polyphyllae中被分离出来,并确定其为主要特征成分,可用于该物种的化学分类学鉴定。通过部分氢化和随后的二甲基二硫醚衍生物的GC/MS分析,结合GC-FT/IR和NMR提供的端基乙烯基团和Z型双键构型的证据,其结构被阐明为1,6,9-十七碳三烯。通过合成,该三烯被鉴定为(Z,Z)-1,6,9-十七碳三烯,并证实其为一种新的天然产物。
