چکیده انگلیسی
⺠13C-labelled precursors were administered to root cultures of Anigozanthos preissii, which were simultaneously incubated in an atmosphere of 18O2. ⺠Incorporated 18O was detected by means of isotope-induced shifts of 13C NMR signals and HREISMS. ⺠The sensitivity with which NMR spectroscopy detected 18O was dramatically enhanced by O-methylation with 13C-diazomethane. ⺠The biosynthetic sequence according to which oxygen functionalities are incorporated from the atmosphere into 9-phenylphenalenones was elucidated.
