Caffeic anhydride from Solanum sodomeum (Solanaceae)

S. sodomeum is distributed in north of Africa, Spain, Portugal, Balearic islands, Corsica, Sardinia, Italy, Sicily, Dalmatia. In Libya it is distributed in Tripoli and Tokra. Phytochemical investigation on the plant has resulted in the isolation of number compounds; the extracts have been used in the indigenous system of medicine for a number of purposes. The phenolic compound I caffeic anhydride has been isolated from the toluene-soluble fraction by column chromatography after hydrolysis at 30 °C in a two-phase system containing an aqueous hydrochloric acid and toluene extract of the fresh berries of the plant, collected from the Libyan coast. Its structure was determined by means of IR, 1H -NMR, 13C-NMR, APT and mass spectra techniques, this is the first report of caffeic anhydride [(2E)-3-(3,4-Dihyroxyphenyl)prop-2-enoic Anhydride;1]from the Solanaceae family.
