Abstract
Two new phenolic compounds, 2-(2-hydroxyphenyl)-4-methoxycarbonyl-5-hydroxybenzofuran (1) and 1-methoxycarbonyl-2, 3-dihydroxydibenzo[b, f]oxepine (2), were isolated from the tuber of Sparganium stoloniferum. The structures of both new compounds were determined on basis of spectroscopic means including HR-ESI-MS, 1D and 2D NMR experiments.
Keywords:
1-methoxycarbonyl-2, 3-dihydroxydibenzo[b, f]oxepine; 2-(2-hydroxyphenyl)-4-methoxycarbonyl-5-hydroxybenzofuran; Sparganiaceae; Sparganium stoloniferum.
