摘要: 为了获得具有抗炎活性的青藤碱衍生物,建立了药用植物内生菌对青藤碱的生物转化模型,从84株药用植物内生菌中筛选出5株对青藤碱具有转化能力的菌株,利用TLC和NMR技术对转化产物进行了结构鉴定,确认为(S)-disinomenine,(R)-disinomenine和sinomenine -N-oxide。生物转化为青藤碱的结构改造提供了研究方向。

Abstract: In order to obtain sinomenine derivatives with anti-inflammatory activity,biotransformation of sinomenine was performed using endophytic fungi from medicinal plants.Among 84 endophytic fungi isolated from medicinal plants,five fungi possessed the capability of biotransforming sinomenine were screened out.The structures of metabolites were identified as(S)-disinomenine,(R)-disinomenine and sinomenine-N-oxide by TLC and NMR.Biotransformation is going to provide a new research direction for structural modification of sinomenine.

Key words: medicinal plant, endophytic fungi, biotransformation, sinomenine
