Two New Benzophenones From the Endohydric Moss Polytrichastrum formosum
NATURAL PRODUCT COMMUNICATIONS(2021)
Abstract
Two new benzophenone derivatives (1 and 2), were obtained from the endohydric moss Polytrichastrum formosum. Their structures were established by 1D and 2D NMR spectroscopic and HRESIMS methods. The cytotoxicity of 1 and 2 against HCT-116, A-549, HepG2 and HeLa cell lines was evaluated, but no obvious cytotoxic activities were observed (IC50 >100 mu M). Benzophenones may be characteristic components of Polytrichaceae.
