title: A new chromene from the fruiting bodies of Chroogomphus rutilus.
abstract: A new chromene, acetic acid 2R-(4,8-dimethylnona-3,7-dienyl)-8-hydroxy-2-methyl-2H-chromen-6-yl ester (1), was isolated from the fruiting bodies of Chroogomphus rutilus, together with six known compounds (2-7). The structures of these compounds were identified based on 1D and 2D NMR, including (1)H-(1)H COSY, HMQC and HMBC spectroscopic methods. Of these seven compounds, 2 and 3 showed cytotoxicity against HSC-T6, SK-Hep1 and A549 cell lines.
