Abstract:
A new phenolic acid ester, 4'-hydroxyphenylethyl 4,8(R)-dihydroxyphenylpropionate(1), was isolated from an endophytic fungus Colletotrichum capsici of Paeonia lactiflora roots, along with eight known phenolic derivatives, tyrosol(2), 2-(4-hydroxyphenyl) ethyl acetate(3), methyl p-hydroxyphenylacetate(4), methyl m-hydroxyphenylacetate(5), 4-(4-hydroxyphene-thoxy)-4-oxobutanoic acid(6), 4-hydroxyphenethyl methyl succinate(7), trichodenol B(8) and 4-hydroxyphenethyl 2-(4-hydroxyphenyl) acetate(9). Their structures were identified by a combination of high-resolution electrospray ionization mass spectrometry(HR-ESI-MS), nuclear magnetic resonance(NMR) spectroscopy, ultraviolet(UV) spectroscopy and electronic circular dichroism(ECD) spectroscopy. Compounds 2-9 were isolated from this fungus for the first time.
