Nine previously-unreported farnesylphenols, involving eight neogrifolin derivatives (1-8) and one grifolin analogue (9), together with three known compounds, were isolated from the fruiting bodies of the mushroom Albatrellus caeruleoporus. Their structures were elucidated as (S)-17-hydroxy-18,20-ene-neogrifolin (1), (S)-18,19-dihydroxyneogrifolin (2), (S)-9-hydroxy-10,22-ene-neogrifolin (3), (9S,10R)-6,10-epoxy-9-hydroxyneo grifolin (4), (9S,10R)-6,9-epoxy-10-hydroxyneogrifolin (5), (-)-13,14-dihydroxyneogrifolin (6), albatrelin G (7), albatrelin H (8), and one grifolin analogue, (S)-10-hydroxygrifolin (9), grifolin (10), neogrifolin (11), and albatrellin (12) by extensive spectroscopic analyses and chemical methods. Compounds 7 and 8 showed weak cytotoxic activity to cell lines HL-60, SMMC-7721, A-549, and MCF-7, in vitro.
