Cytotoxic and antibacterial compounds from Raddi fruits.

Chromatographic procedures of extracts of Raddi fruits afforded -masticadienoic () and 3β-masticadienolic () acids, tetrahydroamentoflavone (), and 4--methyl gallic acid (). Addicionally, the derivative 6-oxo masticadienoic acid () was prepared by an allylic oxidation. The chemical structures of obtained compounds were elucidated by spectrometric data analyses.
