Five new phenolics from the roots of Ficus beecheyana

From the ethanolic extract of the roots of Ficus beecheyana, threo-2,3-bis(4-hydroxy-3-methoxyphenyl)-3-ethoxypropan-1-o1 (1), erythro-2,3-bis(4-hydroxy-3-methoxyphenyl)-3-ethoxypropan-1-o1 (2), trans-4,5-bis(4-hydroxy-3-methoxyphenyl)-1,3-dioxacyclohexane (3), threo-3-(4-hydroxy-3,5-dimethoxyphenyl)-3-ethoxypropane-1,2-diol (4), 2,3-dihydroxy-1-(4-hydroxy-3,5-dimethoxyphenyl)-1-propanone (5), and 3-hydroxy-1-(4-hydroxy-3,5-dimethoxyphenyl)-1-propanone (6) were isolated. The structures of the new compounds 1-5 were elucidated by the analysis of their spectroscopic data.
