木姜子香气成分与生物活性及其代谢途径的研究进展

木姜子作为一种药食两用的香辛料，具有较强的抗菌、抗炎、抗癌等功效，其强烈的柠檬香气，可以去腥增香提味。萜类化合物是木姜子的主要香气成分，以柠檬醛为代表的萜类化合物具有显著的生物活性。木姜子中的关键香气成分包括D-柠檬烯、(Z)-3,7-二甲基-2,6-辛二烯醛、(E)-3,7-二甲基-2,6-辛二烯醛、β-月桂烯、(E)-肉桂酸乙酯和β-石竹烯等。本文主要综述了木姜子在中国的种群分布、香气成分与生物活性的研究进展，以及主要萜类化合物在植物体内的代谢途径，以期对木姜子的资源开发和高附加值利用提供科学依据。

Research Progress on Aroma Compounds and Biological Activity and Their Metabolic Pathways in Litsea pungens Hemsl

Litsea pungens Hemsl (LPH) is one of spicy for both medicine and food for its strong ability of antibacterial, anti-inflammatory and anti-cancer effects and strong lemon aroma characteristic that can remove the fishy odor and increase the overall flavor quality of dishes. The terpenoids are the main aroma compounds in LPH. Citral, the representative terpenoids, has significant biological activities. D-Limonene, (Z)-3,7-dimethyl-2,6-octadienal, (E)-3,7-dimethyl-2,6-octadienal, β-myrcene, ethyl (2E)-3-phenylacrylate, and β-caryophyllene are the key odorants of LPH. This paper mainly introduces the population distributions of LPH in China, recent progressive in aroma compounds, the biological activity, and the metabolic pathway of main terpenoids in LPH so as to provide scientific evidence for the resource development and comprehensive utilization of LPH.
