Two new caryophyllene-type sesquiterpenoids,pestathenols A (1) and B (2) and one new α-furanone,pestatheranone A (6),along with five known compounds (3-5,7 and 8) have been isolated from the crude extract of the plant endophytic fungus Pestalotiopsis theae.Their structures were unambiguously established by extensive spectroscopic analyses.The absolute configuration of the 5,6-diol moiety in 1 was assigned using Snatzke\'s method.Compounds 1 and 2 showed weak cytotoxicity against HeLa cell line.
