Characterisation and Quantification of Flavonoids in Iris germanica L. and Iris pallida Lam. Resinoids from Morocco

“…All of them were reported previously in I . germanica rhizomes (Pailer and Franke, ; Rahman et al , ; Wollenweber et al , ) whereas to the best of our knowledge, only irigenin and irisflorentin were reported in I . pallida rhizomes (Bicchi and Rubiolo, ).…”

“…Using NMR and HPLC-QTOF-MS these compounds were identified as the known isoflavones: irigenin (1), iristectorigenin A (2), nigricin (3), nigricanin (4), irisflorentin (5), iriskumaonin methyl ether (6), irilone (7) and iriflogenin (8) ( Table 2). All of them were reported previously in I. germanica rhizomes (Pailer and Franke, 1973;Rahman et al, 2003;Wollenweber et al, 2003) whereas to the best of our knowledge, only irigenin and irisflorentin were reported in I. pallida rhizomes (Bicchi and Rubiolo, 1993). Compound 9 from I. germanica resinoid was identified by NMR and HPLC-QTOF-MS as a known isoflavone: irisolidone (Table 2).…”

Isoflavonoid production by adventitious-root cultures of Iris germanica (Iridaceae)

“…Thus, the plants of this genus can be nice materials to explore the mechanism of biosynthesis and the physiological functions of non-leguminous isoflavonoids. German iris, Iris germanica L., is known for the accumulation of a number of isoflavones (Dhar and Kalla 1972;Pailer and Franke 1973;Ali et al 1983;Atta-urRahman et al 2002), and in vitro plant regeneration from embryogenic calli has also been reported (Jéhan et al 1994;Shimizu et al 1996). In the present study, we cultured adventitious roots of I. germanica, and analyzed the accumulation of free and conjugated isoflavones.…”

“…Irigenin (Pailer and Franke 1973;Ali et al 1983), iristectorigenin A (Pailer and Franke 1973) and iridin (Dhar and Kalla 1972;Atta-ur-Rahman et al 2002) are constituents of the rhizome of I. germanica. Iristectorin A has been reported from Iris tectorum (Morita et al 1972), Iris spuria (Shawl et al 1984) and Iris kumaonensis (Mahmood et al 2002).…”
