摘要： 红景天苷主要来源于红景天，是红景天属植物的重要活性物质，具有抗辐射、抗缺氧、抗肿瘤等多种药用功效。由于红景天野生资源少，且红景天苷在红景天中含量极少、提取率低，因此，研究提高红景天苷产量的生产方法具有重要的意义和价值。在研究红景天苷生物合成机制的基础上，通过基因工程技术来提高红景天苷的产量具有一定的前景和研究价值。综述了红景天苷的生物合成机制、代谢途径中的关键酶和利用代谢工程合成红景天苷的方法，并对其研究前景进行了展望，以期为红景天苷的生物合成相关研究提供参考。

Abstract: Salidroside, mainly from Rhodiola rosea, is an important active substance from Rhodiola plants and has diversified medicinal efficacy such as radiation resistance, hypoxia resistance, tumor resistance, etc. Because of limited source of wild Rhodiola  rosea, extremely low ratio of Salidroside in Rhodiola rosea  and low extraction rate of Salidroside, it is important and valuable to study production methods that could increase the output of Salidroside. Studying on Salidroside biosynthesis mechanism and using genetic engineering techniques to increase the output of Salidroside would have certain extent of promising prospect and value of study. This paper gave an overview of Salidroside biosynthesis mechanism, key enzymes in the metabolic pathway and the Salidroside synthesis method by means of metabolic engineering, followed by proposing the prospect of this study, which was expected to provide reference for research on Salidroside biosynthesis.

Key words: salidroside, key enzymes, metabolic engineering
