摘要: 为了解云南道地药材滇龙胆内生真菌的菌落结构及代谢产物的抑菌活性,采用组织块法分离健康滇龙胆植株根、茎、叶中的内生真菌,并根据菌落和镜下特征对其进行初步形态学鉴定.并通过滤纸片法对分离得到的内生真菌进行抑菌活性筛选.从滇龙胆根、茎、叶中共分离到49株内生真菌,分别属于15个属,其中有11属,23株对至少1种指示菌有抗菌活性,占总分离菌株的46.9%.本试验研究了滇龙胆内生真菌的种群分布,获得了一些具有抑菌活性的内生真菌,为寻找新的抗菌药物奠定基础.

Abstract: In order to understand the colony structure and antimicrobial activity of endophytic fungi from Gentiana in Yunnan, the endophytic fungi in root, stem and leaf of healthy Gentiana were isolated by tissue block method, their morphological identification was carried out according to colony and microscopic characteristics, and the antifungal activity of the isolated endophytic fungi was screened by filter paper method. 49 endophytic fungi were isolated from the roots, stems and leaves of Gentiana, belonging to 15 genera, of which 11 genera and 23 strains had antibacterial activity to at least 1 indicative bacteria, accounting for 46.9% of the total Yunnan Gentiana. In this study, the population distribution of endophytic fungi in Yunnan Gentiana was studied, and some endophytic fungi with antimicrobial activity were obtained, which laid a foundation for the search for new antibacterial agents.

Key words: Yunnan Gentiana, endophytic fungi, antimicrobial activity
