Abstract
Genus Iris (Iredaceae) comprises over 300 species; 12 of them are present in Iraq. Iris persica has been used in Kurdish traditional medicine for the treatment of wound inflammation and tumor. However, Chemical and biological aspects of I. persica have not yet been investigated. The present study reports the first investigation on the isolation and characterisation of bioactive compounds from flowers, bulbs and rhizomes of I. persica that has been collected from Kurdistan Region-Iraq and cytotoxicity effect of the isolated compounds against six human cancer cell lines were evaluated.
Dry flowers, bulbs and rhizomes of I. persica were exhaustively extracted by maceration at room temperature, solvents of increasing polarity: hexane, methanol, methanol/water 70:30. Chlorophylls were removed from the methanolic extracts of flowers by filtration on a C-18 reversed phase column. Subsequently, the methanolic extracts of the flowers, bulbs and rhizomes were separately fractionated by repetitive preparative MPLC, on C-18 reversed phase, affording four compounds as the major products: tectorigenin (1), embinin (2), isovitexin (3) and trans-resveratrol-3-O-β-D-glucopyronoside (4). The structures of the compounds were identified on the basis of spectroscopic analyses and comparison with literature data.
