摘要: 本文通过对毛脉酸模内生真菌的发酵培养得到其次生代谢产物,采用HPLC法对内生真菌中蒽醌类成分进行筛选。以大黄素、大黄酸、大黄酚、大黄素甲醚、芦荟大黄素五种蒽醌类成分为参照,筛选出3株真菌含大黄素、3株真菌含大黄酸、5株真菌含芦荟大黄素,其中含量最高为683 μg/g、最低为8 μg/g。将各菌株所含成分与各菌株分离部位的相应成分进行比较,相对宿主植物而言各菌株均有较高的含量。本实验分析方法准确、快捷,适用于毛脉酸模内生真菌的代谢产物研究。

Abstract: In this paper,the secondary metabolites of anthraquinones were obtained by fermentation of endophytic fungi of Rumex gmelini Turcz..HPLC was used to filter different anthraquinones from endophytic fungi of R. gmelini.With 5 anthraquinone compounds,including emodin,rhein,chrysophanol,physcion and aloeemodin as reference,the endophytic fungi with the secondary metabolites of anthraquinones were screened out,in which 3 strains were screened out to contain emodin,3 strains contained rhein,and 5 strains contained aloe-emodin.Among these fungi,the highest and lowest yield of anthraquinones was 683 μg/g and 8 μg/g,respectively.The strains had higher concentrations of anthraquinones between each strains and its respective separated parts in R. gmelini. The developed HPLC method was accurate and fast,and it was applicable to analysis metabolites of endophytic fungi from R. gmelini.

Key words: Rumex gmelini Turcz., endophytic fungi, HPLC, anthraquinones secondary metabolites
