Anacyclus pyrethrum D.C. (Compositae) contains N-(2′-p-hydroxyphenylethyl) deca-, dodeca-, and tetradeca-trans-2, trans-4-dienamide, a new series of tyramine amides corresponding to isobutylamides which this plant produces. The tyramides, and the corresponding isobutylamides, are synthesised stereospecifically by phosphonatenaion synthesis. Anacyclus pyrethrum is found to contain the lignan (+)-sesamin and attention is drawn to the cooccurrence of lipid (and other) amides with lignans in a number of plants from three families (Compositae, Piperaceae, and Rutaceae).
安卡菊(Anacyclus pyrethrum D.C.,菊科)含有新系列的酪胺酰胺,即N-(2′-对羟基苯乙基)癸基、十二基和十四基反式-2,反式-4-二烯酰胺,这些化合物对应于该植物产生的异丁基酰胺。酪胺酰胺及其相应的异丁基酰胺是通过磷酸钠特定的立体选择性合成得到的。研究发现,安卡菊中还含有木脂素(+)-芝麻素,并指出在来自三个科(菊科、胡椒科和芸香科)的多种植物中,脂质(及其他)酰胺与木脂素的共存现象值得关注。
