Two new compounds from the ascomycete Daldinia concentrica

Two new compounds, 1-isopropyl-2,7-dimethylnaphthalene (1) and 21-(acetyloxy)-6,13,14-trihydroxy-16,18-dimethyl- 10-phenyl[11]cytochalasa-7,19-dien-1-one (2), were isolated from the fruiting bodies of Daldinia concentrica. The structures were established by spectroscopic methods.
