摘要: 目的:对分离到的一株具产生物碱活性的藜芦植物内生真菌Ym 312628进行次生代谢产物研究,确定其化合物结构,以期为生物碱类药物提供更广阔的来源.方法:应用正交实验,跟踪生物碱活性,确定菌株Ym 312628的最佳发酵条件,应用各种层析柱对其发酵产物进行纯化分离,经光谱分析确定其化学结构.结果:分离得到7个化合物,其中3个结构鉴定为3-苯基乳酸、5-丁基吡啶甲酸、啤酒甾醇,1个麦角甾醇类物质具体结构还需进一步鉴定;以及三个生物碱阳性反应物质,初步鉴定为一类带有核苷酸单元的结构类似物,但具体化学结构需进一步鉴定.结论:菌株Ym 312628的代谢产物3-苯基乳酸对生产丹参素的替代品提供了有效途径.

Abstract: Objective To study the secondary metabolites of an endophytic fungus Ym 312628, an endophytic fungus with the activity of alkaloid, to determine the structure of the compound in order to provide a wider source of alkaloid drugs. Methods The optimum fermentation conditions of strain Ym 312628 were determined by orthogonal experiment, and the fermentation products were purified and separated by various chromatographic columns, and the chemical structure was determined by spectral analysis. Results 7 compounds were isolated and 3 of them were identified as 3- phenyl lactic acid, 5- butyl pyridine formic acid, and beer sterol. The specific structure of 1 ergosterols was further identified, and three alkaloid positive reactions were identified as a class of structural analogues with nucleotide units, but the specific chemical junctions were identified. Further identification is required. Conclusion The metabolite of strain Ym 312628 3- phenyl lactic acid provides an effective way to produce Salviae Miltiorrhizae substitutes.
