| cyclic azaphilones daldinins e and f from the ascomycete fungus hypoxylon fuscum (xylariaceae). | phytochemical examination of the methanolic extract of fruit bodies of the xylariaceous ascomycete fungus hypoxylon fuscum led to the isolation of two azaphilone derivatives named daldinins e and f together with two known compounds daldinin c and 4,5,4',5'-tetrahydroxy-1:1'-binaphthyl using a combination of reversed phase hplc and high performance gel permeation chromatography. their structures were determined by 2d nmr, ms, ir, uv, and cd spectroscopy. their antioxidative activities were also e ... | 2004 | 14759543 |
