药用植物内生菌抗氧化活性研究进展

内生菌是存在于植物组织内部但不会对植物有明显负面影响的一类重要的生物资源。内生菌与宿主植物经过长期进化,通过产生各种特定的活性物质相互作用维系相对稳定的共生关系。药用植物内生菌成为筛选新的活性成分和先导化合物的重要途径,其中抗氧化活性物质是一类最受关注的活性成分。药用植物中抗氧化活性内生菌多样性丰富,特别是内生真菌和内生放线菌。从抗氧化活性内生菌与宿主植物的关系及生态学意义、抗氧化活性内生菌物种多样性和活性成分多样性等几个方面总结了植物内生菌抗氧化活性的研究进展,并对该领域今后的发展方向进行了展望。

Recent progress in study on anti-oxidant activity of endophytes in medicinal plants

Endophyte is a significant biological resource which exists in plant cells without any negative effects for plants. After a long period of evolution, endophyte and its host plants keep a relatively stable symbiosis by producing some special active ingredients. Therefore, plant endophyte is the essential source of active ingredients and leading compound, while antioxidants attract the most attention of all ingredients. There is abundant diversity of antioxidant activity endophytes in medicinal plants, especially endophytic fungi and endophytic actinomyces. Here we summarize the recent research progress in the antioxidant activity endophytes from the relationship between the antioxidant activity endophytes and host plants, their ecological significance, diversity of antioxidant activity endophytes, and active ingredients. And the future research and development direction of this field is prospected.
