黑果枸杞内生真菌RER4化学成分研究
Chemical constituents of endophytic fungi RER4 from Lycium ruthenicum
摘要
Abstract
The fungus strain RER4 isolated from the root of Lycium ruthenicum .Was identi‐fied as A spergillus oryz ae by its morphological characteristics and internal transcrised spacer (ITS) sequence analyses .Solid state fermentation was used to culture the endophytic fungi RER4 on the rice medium ,8 compounds were isolated and purified from the eyhyl acetate ex‐tract of endophytic fungi RER4 by various chromatographic methods and their structures were ergosterol ,5‐hydroxy‐benzofuran‐2 (3H )‐one ,3‐hydroxy‐3‐(methoxycarb onyl) pen‐tanedi‐oic acid ,succinic acid ,2‐hydroxy‐4‐methoxy‐2‐(2‐meth oxy‐2‐oxoethyl )‐4‐oxobutan‐oic acid ,erythritol ,mannitol ,adonitol by ESI‐MS and NMR .Among compound 5‐hydroxy‐benzofuran‐2(3H)‐one was firstly isolated from the medium of Aspergillus oryzae .关键词
