Five new mixed terpenoids, tricycloalternarenes (TCAs) A–E ( 1 – 5 ), together with two known compounds, TCA 1b ( 6 ) and TCA 2b ( 7 ), were isolated from the solid‐state‐cultured endophytic fungus Alternaria alternata of Maytenus hookeri. Their structures were identified by extensive spectroscopic (especially 2D‐NMR) experiments. Compound 7 showed weak activity against human tumor cell lines by MTT assay.
