The defensive secretion of the "daddy longlegs" Leiobunum vittatum was analyzed and found to contain the acyclic ketones 4-methylheptan-3-one and E-4,6-dimethyl-6-octen-3-one as its major organic components. Although 4-methylheptan-3-one has been found previously as an alarm substance in certain ant genera, the second component, whose structure is confirmed by synthesis, is new.
对长脚蛛Leiobunum vittatum的防御性分泌物进行了分析,发现其主要有机成分包含无环酮4-甲基庚-3-酮和E-4,6-二甲基-6-辛烯-3-酮。虽然4-甲基庚-3-酮此前已在某些蚁属中作为警戒物质被发现,但经合成确认结构的第二种成分却是新发现的。
