In recent years, more and more researches focus on endophytic fungi derived from important medicinal plants, which can produce the same bioactive metabolites as their host plants. Salvia miltiorrhiza Bunge is a traditional medicinal plant with versatile pharmacological effects. But the wild plant resource has been in short supply due to the overcollection for bioactive metabolites. Our study was therefore conducted to isolate endophytic fungi from S. miltiorrhiza and get candidate strains that produce the same bioactive compounds as the plant. As a result, an endophyte that produces salvianolic acid C was obtained and identified as Phoma glomerata D14 based on its morphology and internal transcribed spacer analysis. Salvianolic acid C was found present in both the mycelia and fermentation broth. Our study indicates that the endophytic fungus has significant industrial potential to meet the pharmaceutical demands for salvianolic acid C in a cost-effective, easily accessible, and reproducible way.
近年来,越来越多的研究聚焦于源自重要药用植物的内生真菌,这些内生真菌能够产生与宿主植物相同的生物活性代谢产物。丹参是一种具有多种药理作用的传统药用植物。但由于对生物活性代谢产物的过度采集,野生植物资源一直供不应求。因此,我们开展了从丹参中分离内生真菌的研究,并获得了能够产生与该植物相同生物活性化合物的候选菌株。结果,获得了一株能产生丹酚酸C的内生菌,根据其形态和内转录间隔区分析,鉴定为聚生茎点霉D14。在菌丝体和发酵液中均发现了丹酚酸C。我们的研究表明,这种内生真菌具有巨大的产业潜力,能够以经济高效、易于获取且可重复的方式满足对丹酚酸C的药用需求。
