Two new meroterpenoids, arisugacins I (1) and J (2), together with five known meroterpenoids including arisugacin B (3), arisugacin F (4), arisugacin G (5), territrem B (6) and territrem C (7) were isolated from an endophytic fungus Penicillium sp. SXH-65. Their structures were determined by extensive spectroscopic experiments and comparison with literature data. Their cytotoxicities were evaluated against Hela, HL-60 and K562 cell lines, and only 3 and 4 exhibited weak cytotoxicities against Hela, HL-60 and K562 cell lines with IC50 values ranging from 24 to 60 μM.
