In this study, we report on in vitro incorporation experiments of several labelled fatty acids in the ladybird alkaloids coccinelline (Coccinella 7-punctata), adaline (Adalia 2-punctata), and harmonine (Harmonia axyridis). The obtained results clearly indicate that stearic acid is the precursor of coccinelline and harmonine, whereas myristic acid is at the origin of the carbon skeleton of adaline.
在这项研究中,我们报告了几种标记脂肪酸在瓢虫生物碱瓢虫碱 (Coccinella 7-punctata)、阿达琳 (Adalia 2-punctata) 和和谐 (Harmonia axyridis) 中的体外掺入实验。所得结果清楚地表明,硬脂酸是瓢虫碱和海葵碱的前体,而肉豆蔻酸是阿达林碳骨架的起源。介绍了这些生物碱生物合成的可能途径。
