Ganoderpetchoids A-E and (-)-dayaolingzhiol H, six undescribed meroterpenoids, were isolated from Ganoderma petchii. Their structures including the relative configurations were identified by means of spectroscopic methods and C NMR calculations. Chiral separation of the new racemics was performed to afford their respective enantiomers. The absolute configurations of the new isolates were clarified by computational approaches, CD comparisons and X-ray diffraction analysis. Biological studies toward triple negative breast cancer indicated that (+)-6 and (-)-6 significantly inhibit the migration of MDA-MB-231 cell line.
