These data were used to infer the molecular formula and the elemental compositions of all the fragmental ions through software interpretation and, by further applying fragmentation regularities of mass spectrometry, the majority of ions were fully assigned. A base peak at m/z 402 in the mass spectrum was found as the molecular ion. The fragments were created mainly from the fragmentations of the tetrahydrofuran rings and the hydroxyl group. The most fragment products contain the dimethoxy phenyl group.
