New Prenylated Flavones from the Roots of Ficus Beecheyana

Abstract 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‐hydroxy‐cinnamic acid, seseline, xanthyletin, and psoralene. The structures of these secondary metabolites were determined by spectroscopic means and in comparison with published data.
