Abstract

The monohydroxy carotenoid from the moth Cerura vinula has been shown to be beta, beta-caroten-2-ol on the basis of electronic, infrared, proton magnetic-resonance, and mass spectra. On acid treatment in the presence of molecular oxygen this carotenoid is dehydrogenated to 4',5-retro-beta,beta-caroten-2-one. The identification of beta,beta-caroten-2-ol by its retro product, its time course of acetylation, and its chromatographic properties relative to beta,beta-caroten-3-ol and beta,beta-caroten-4-ol is discussed. This is the first demonstration of a 2-hydroxylated carotenoid in an insect. Implications on the biogenesis of this pigment are considered.

摘要

基于电子光谱、红外光谱、质子磁共振光谱和质谱分析，已证明来自葡萄天蛾（Cerura vinula）的单羟基类胡萝卜素为β,β-胡萝卜素-2-醇。在分子氧存在下进行酸处理时，这种类胡萝卜素会脱氢生成4',5-反式-β,β-胡萝卜素-2-酮。文中讨论了通过其反式产物、乙酰化的时间进程以及相对于β,β-胡萝卜素-3-醇和β,β-胡萝卜素-4-醇的色谱性质对β,β-胡萝卜素-2-醇进行鉴定的方法。这是首次在昆虫中证实存在2-羟基化类胡萝卜素。文中还考虑了这种色素生物合成的相关影响因素。
