Identification and Secondary Metabolites of Endophytic Fungus MD76 from Paeonia suffruticosa / 中国药学杂志

ABSTRACT

In order to identify the endophytic fungus MD76 and isolate its secondary metabolite. METHODS: The identification of strain MD76 is based on morphological characteristics and sequence alignment analysis of 18s rDNA ITS, the secondary metabolites were isolated by chromatography technology; and their structures were elucidated by extensive spectroscopic analysis. RESULTS: The strain MD76 was identified as Phyllosticta capitalensis; and seven compounds were gained, including benzoic acid(1), 4-hydroxybenzoic acid(2), 4-hydroxybenzene propanoic acid(3), paeoniflorin(4), oxypaeoniflorin(5), gallic acid(6), apigenin(7). CONCLUSION: The endophytic fungus P. capitalensis was gained firstly from Paeonia suffruticosa and seven compounds were isolated from P. capitalensis for the first time.
