Chemical constituents from the stem of Ficus pumila

A new biphenyl compound: 5-aldehyde-4′-hydroxy-2,2′-dimethoxybiphenyl (1), along with 11 known phenolic compounds (2–12) were isolated from the stem of Ficus pumila Linn. Their structures were established by spectroscopic methods, including MS, UV, IR, 1 D and 2 D NMR. Compounds 4 and 10 showed weakly cytotoxicity against MCF-7, with IC₅₀ values of 32.5 and 37.3 µM, respectively.
