Compound 1 was obtained as a yellow amorphous powder
and its UV spectrum showed absorption maxima at 216.5, 258.4
and 328.5 nm. The positive HR-FAB-MS spectrum of 1 revealed
the [M+H]+ at m/z 491.2434 corresponding to the molecular
formula C30H35O6. The 1H and 13C NMR data of 1 showed that
the compound was closely related to the co-occurring 6 and 7
except for the appearance of a geranyl group instead of the
chromenesmoiety. TheHMBC correlations
