The structure of the polyacetylenic keto-aldehyde H2CCH·CO·[CC]2·CH2·CH[graphic omitted]CH·[CH2]7·CHO} has been determined. It is the first C18 polyacetylene to be isolated from a plant (Pastinaca sativa L.) of the main polyacetylene-producing families. Its occurrence almost certainly establishes the derivation of the C17 falcarinone and related compounds and is in harmony with Bu'Lock's hypothesis
的聚炔酮醛的结构H 2 C ^ CH·CO·[C C] 2 ·CH 2 ·CH [图形省略] CH·[CH 2 ] 7 ·CHO}已经确定。这是第一个C 18聚乙炔被从植物(隔绝Pastinaca苜蓿主聚乙炔生产家庭L.)。它的出现几乎可以肯定地确定了C 17 falcarinone及其相关化合物的衍生物,并且与Bu'Lock关于天然乙炔的生物发生的假设相一致。
