Abstract: Three new benzene derivatives, named daldins A-C (1-3), together with a known analogue, 2-hydroxymethyl-3-(1-hydroxypropyl) phenol (4) have been isolated from cultures of ascomycete Daldinia concentrica. The structures of 1-4 with absolute configuration were established by means of spectroscopic methods and X-ray diffraction. All compounds showed no significant inhibition on five human cancer cell lines with IC50 values > 40 μmol.

Key words: Daldinia concentrica, benzene derivatives, absolute configuration
