title: Secondary metabolites of Tubercularia sp. TF5, an endophytic fungal strain of Taxus mairei.
abstract: One new diterpene glycoside (1) named 16-O-alpha-D-tetraacetylglucopyranosyl hymatoxin C, along with eight known ones including two diterpenoids (2, 3), three cytochalasins (4, 5, 6), dihydroisocoumarin (7) and two C(7)-tetraketides (8, 9), were isolated from the culture of the endophytic fungal strain Tubercularia sp. TF5. The structures of compounds 1-9 were elucidated by spectroscopic methods. The cytotoxic and antimicrobial activities of 1 were analysed but showed no significant activities.
