The extract was sequentially eluted through silica gel with PE and PE/ethyl acetate （EA） mixed solvents （volume ratio 2：1 ） to afford two eluted frac- tions. The extract and eluted fractions were analyzed with gas chromatography/mass spectrometry. In total, 14 arenols were detected, including phenol, cresols, xylenols, fluorenols, phenanthren-3-ol and pyren-l-ol.展开更多
