| 中文摘要: |
| 三萜是许多药用植物的活性成分，由于结构相对复杂，植物中含量较低，通过提取分离或化学合成难以获得，其应用受到限制。目前对三萜类成分的生物合成研究已取得一定的进展，其中氧鲨烯环化酶（OSC）可催化2，3-氧化鲨烯环化生成三萜类前体物质，细胞色素P450（CYP450）主要参与三萜的后修饰过程，对三萜的多样性起着关键作用。通过OSC和CYP450在三萜生物合成中的催化功能的综述，以期为进一步探索OSC和CYP450在三萜生物合成中的功能研究提供思路。 |
| 英文摘要: |
| Triterpenes， the active ingredients of many medicinal plants， are difficult to be extracted， separated or chemical synthesized because of their complex structures and low amount in plants. Thus， the application of triterpenes is extensively limited. Until now， progress on the triterpene biosynthesis pathway has been made to some progress. Notably， oxidosqualene cyclase (OSC) can catalyze 2，3-oxidosqualene cyclization to generate precursors of triterpene. And cytochrome P450 (CYP450) is mainly involved in the post-modification process， playing a key role in the diversity of triterpenes. The aim of present study is to provide ideas for the functional research of key enzymes in triterpene biosynthesis by reviewing the researches about the catalytic function of OSC and CYP450 in triterpene biosynthesis. |
