Chemical Constituents from the Fungus Inonotus sinensis
摘要
A new isopimarane-type diterpenoid, named inonotolide E (1), and four known compounds (2–5) were isolated from cultures of the fungus Inonotus sinensis. The new structure was established by extensive spectroscopic techniques (1D and 2D NMR and HR-ESI-MS). Compound 1 was evaluated for its cytotoxicities against five human cancer cell lines.
