Two new prenylated flavanones, ficubee A and ficubee B, respectively, as 7,8-(2,2-dimethylpyrano)-6-prenyl-5,3′,4′-trihydroxyflavone and 6,7-(2,2-dimethylpyrano)-8-prenyl-5,3′,4′-trihydroxyflavone were isolated from the roots of Ficus beecheyana together with twelve known compounds: β-sitosterol, 5-stigmasten-3β,7α-diol, 5-stigmasten-3β,7β-diol, 3β-hydroxystigmast-5-en-7-one, 4-hydroxybenzaldehyde, 4-hydroxy-3-methoxybenzaldehyde, 1-(4-hydroxyphenyl)- ethanone, 4-hydroxy-3-methoxybenzoic acid, 4-hydroxycinnamic acid, seseline, xanthyletin, and psoralene. The structures of these secondary metabolites were determined by spectroscopic means and in comparison with published data.
