摘要:

对异色瓢虫(Harmonia axyridis)共生真菌木贼镰刀菌(Fusarium equiseti)的次生代谢产物研究.通过硅胶、凝胶(Sephadex LH-20)、反相硅胶-C 18(ODS-C 18)柱层析法对甲醇提取部分的成分进行分离,采用质谱和核磁共振等手段鉴定结构.从木贼镰刀菌的甲醇提取物中分离鉴定了5个化合物.

The aim of this research is to study the secondary metabolites of the symbiotic fungu Fusarium equiseti from Harmonia axyridis.The components of methanol extraction were isolated by column chromatographyon silicagel and SephadexLH-20.The structure of compounds was established on the basis of 1D/2D NMR spectroscopic and HRESIMS data.Five compounds were isolated and identified as Equiseti A(1),ZSU-H85A(2),4-hydroxy-17R-methylincisterol(3),cerevisterol(4),ergosterol peroxide(5).
