COUMARINS OF MURRAYA EXOTICA - ABSOLUTE CONFIGURATION OF AURAPTENOL

Article abstract of DOI:10.1016/S0031-9422(00)86993-9

3,5,6,7,3',4',5'-Heptamethoxyflavone, 3,5,6,8,3',4',5'-heptamethoxyflavone and murrangatin together with auraptenol and meranzin hydrate have been isolated from Murraya exotica.This is the first report of auraptenol and meranzin hydrate in this species and the first isolation of auraptenol from a natural source.The absolute configuration of auraptenol has been determined and found to possess S configuration at C-2'.The (13)C NMR spectrum of auraptenol acetate has been studied.Key Word Index - Murraya exotica; Rutaceae; coumarins; auraptenol; absolute configuration; (13)C NMR spectra of auraptenol acetate; meranzin hydrate.
