摘要: Abstract A new naphthoquinone compound named 7-hydroxyl-8-methoxyltrypethelone 3 together with two known compounds trypethelone 1 and methyl ether 2 was isolated from cultured mycobiont of Astrothelium sp. The structures were elucidated by 1D 2D NMR spectroscopic analysis as well comparison those reported in literatures. Compound displayed significant antibacterial activity against Bacillus subtilis (ATCC 6633), showed modest Staphylococcus aureus col (MRSA) (CGMCC 1.2465), while Enterococcus faecalis 850E 1.2135) S. 1.2465).
