A New Diphenylethylene from Arundina graminifolia and Its Cytotoxicity

摘要

A now diphenylethylenes, gramniphenol J (1), was isolated from Arundina graminifolia. Its structure was elucidated by spectroscopic methods including extensive 1D- and 2D-NMR techniques. Compound 1 was evaluated for its cytotoxicity against five human tumor cell lines and showed cytotoxicity against PC3 and SHSY5Y cells with IC_(50) values of 8.2 and 7.6 μM.
