ABSTRACT
A new abietane-type diterpenoid, dalterpenoid A (1), a new long-chain alkenone derivative, (3E,5E,10E)-8-hydroxytrideca-3,5,10,12-tetraen-2-one (2), together with six known compounds (3-8), namely epi-guaidiol A (3), xylaranol A (4), daldinone C (5), trans-3,4-dihydroxy-3,4-dihydro-anofinic acid (6), (R)-6-hydroxymellein (7), helicascolide A (8), were obtained from fungus Daldinia sp. TJ403-LS1, which was originally isolated from roots of the medicinally valuable plant Anoectochilus roxburghii. The structures of compounds 1 and 2 were established based on widespread spectroscopic methods, mainly including 1D & 2D NMR and HRESIMS analyses, and the absolute configuration of 1 was further confirmed by electronic circular dichroism (ECD) calculation. All new compounds were tested for the in vitro cytotoxicity against five human cancer cell lines.
