Two new benzophenones from endohydric moss Polytrichum Commune.

Two new benzophenones (1 and 2), were isolated from the endohydric moss Polytrichum commune. Their structures were elucidated by spectroscopic methods including extensive 2 D NMR techniques. Compound 2 is the first example of benzophenone with a rare cyclopropylacetamide from the natural resources. Compounds 1 and 2 were screened their cytotoxicity against five cancer cell lines (HCT-116, A-549, MCF-7, HepG2, A-375,), and no cytotoxic activities were observed (IC₅₀ > 100 μM).
