LAETANINE, ICARISIDE E3, (-)-PINORESINOL AND MANTOL O-Β-D-GLUCOPYRANOSIDE, FROM AQUEOUS EXTRACT OF PHOEBE TAVOYANA (MEISSN) HOOK
Keywords:Phoebe tavoyana, alkaloid, lignan
Four compounds including laetanine (1), icariside E3 (2), (-)-pinoresinol (3) and maltol O-β-D-glucopyranoside (4) were isolated from aqueous extract of Phoebe tavoyana (Meissn) Hook. Their chemical structures were determined based on their ESI-MS, 1D-NMR and 2D-NMR spectral data, and compared with those reported in the literature. This is the first report of compound 2 and 4 from genus Phoebe.
