摘要: 对菌株Trichoderma sp.KK19L1液体发酵,在该菌发酵液的乙酸乙酯层分离得到三个化合物,运用1H-NMR、13C-NMR和HR-ESI-MS等光谱学方法并参考相应的文献,确定其结构分别为(E)-3-acetylbenzyl but-2-enoate(1)、1-羟基-6-甲基-9,10-蒽醌(2)、2-甲基-3-羟甲基-5-羟基-7-甲氧基色原酮(3),其中化合物1为新的化合物,化合物3为首次在该菌株中分离得到。

Abstract: Three compounds with one new compound were isolated from the fermentation broth of Trichoderma sp.KK19L1.Based on 1D NMR,2D NMR,high resolution MS and IR analyses,their structures were elucidated as (E)-3-acetylbenzyl but-2-enoate(1),1-hydroxy-6-Methyl-9,10-anthraquinone(2),5-hydroxy-3-hydroxymethyl-2-methyl-7-methoxychromone(3).Compound 1 is a new compound,and compound 3 was isolatedfrom this genus of fungus for the first time.

Key words: Trichoderma, secondary metabolite, chromone, anthraquinone
