BETA-环柠檬醛是一种化学物质,是合成香料和类胡萝卜素等萜类化合物的重要中间体。例如,它可以用于合成二氢突厥酮、突厥酮(damascenone)及胡罗卜素。
制备方法将紫罗兰酮与甲醇按1∶4~1∶5(质量比)的比例放入三口反应瓶中搅匀,开启冷冻机使反应温度保持在-30±5℃。通过氧气通入臭氧发生器产生臭气,并将其返入反应瓶中,控制通入量为n(紫罗兰酮)∶n(臭氧)=1∶1.15~1∶1.50,反应4~6小时。反应完成后,在反应瓶中加入还原剂、酸及水搅拌均匀,在-30℃~20℃下反应0.5小时,随后调温至20~25℃反应1小时。反应结束后,加入有机溶剂进行萃取、分离、回收有机溶剂得BETA-环柠檬醛粗产品,再通过真空精馏得到一定纯度的BETA-环柠檬醛。
生物活性β-Cyclocitral 是 β-胡萝卜素的挥发性氧化衍生物,是微囊藻特有的掠食性动物防御信号。它是主要的挥发性萜类化合物之一,可以上调防御基因的表达,从而增强对过量光照 (EL) 的适应性。此外,β-Cyclocitral 还是一种强大的驱虫剂。
体外研究β-Cyclocitral 来源于 β-胡萝卜素的催化分解,并有证据表明它是由微囊藻(Microcystis)的所有物种通过激活特定类胡萝卜素氧化酶而产生的。研究表明,β-cyclocitral 能够影响掠食性动物的行为。
