New constituents from the rhizomes of Egyptian Iris germanica L.
Chemical investigation of the methanolic extract of the rhizomes of Iris germanica L. (Iridaceae) afforded two new compounds; irigenin S (7) and iriside A (12), together with ten known compounds: stigmasterol (1), a-irone (2), γ-irone (3), 3-hydroxy-5-methoxyacetophenone (4), irilone (5), irisolidone (6), irigenin (8), stigmasterol-3-O-β-D-glucopyranoside (9), irilone 4'-O-β-D-glucopyranoside (...
متن کاملIsoflavonoid glycosides from the rhizomes of Iris germanica.
Four isoflavone glycosides were isolated from the rhizomes of Iris germanica. Compounds 1 and 2 are new, while compounds 3 and 4 are known isoflavone glycosides. These compounds were identified as iriskashmirianin 4'-O-beta-D-glucoside (1), nigricin 4'-O-beta-D-glucoside (2), irilone 4'-O-beta-D-glucoside (3) and iridin (4). Their structures were determined with the help of spectroscopic methods.
متن کاملMolluscicidal activity and new flavonoids from Egyptian Iris germanica L. (var. alba).
The molluscicidal activity of leaf and rhizome extracts of Iris germanica L. (var. alba) against Biomphalaria alexandrina snails was evaluated and the rhizome extracts were found to be the most potent. Activity-guided fractionation revealed that the chloroform extract showed the highest molluscicidal activity (LC90 = 1.26 mg/l) among the tested extracts of the rhizomes. Fraction B prepared from...
متن کاملNew cytotoxic lanostanoid triterpenes from Ganoderma lingzhi
Further chemical investigation of the metabolites in the fruiting bodies of Ganoderma lingzhi resulted in isolation of eight triterpenes; two of them are new triterpene acid ethyl esters. Their structures were established based on spectroscopic studies and comparison with the known related compounds. The anticancer potential of the isolates were tested with an in vitro cytotoxic assay against f...
متن کاملIsoflavonoid production by adventitious-root cultures of Iris germanica (Iridaceae)
We established the adventitious-root cultures of Iris germanica, a monocotyledonous plant known for isoflavonoid production. Irigenin (5,7,3 -trihydroxy-6,4 ,5 -trimethoxyisoflavone) and iristectorigenin A (5,7,3 -trihydroxy6,4 -dimethoxyisoflavone) along with their 7-O-b-D-glucosides, iridin and iristectorin A, respectively, were found as the major components in adventitious roots in the liqui...
