2-苯乙醇具有愉悦的果香和蜂蜜香味,不仅是植物果实和许多鲜花中重要的香气化合物,并且还具有抗菌和昆虫引诱作用。目前关于2-苯乙醇的代谢途径仅在番茄、玫瑰花、矮牵牛花中有研究和报道,并已从番茄、玫瑰花等植物中克隆到编码其生物合成关键酶的全长基因。综述了植物中2-苯乙醇代谢合成途径的最新研究进展,并对其研究前景进行了展望。 2-Phenethyl alcohol has pleasing fruit and honey aromas and is not only a key aroma compound in plant fruits and many flowers, but also has antibacterial and insect attractant functions. At present, the metabolic pathway of 2-phenylethanol is only studied and reported in tomato, rose and petunia. The full-length gene encoding the key enzyme of biosynthesis has been cloned from plants such as tomato and rose. The latest research progress of 2-phenyl ethanol metabolism pathway in plants was reviewed, and the prospect of the research was prospected.
