BACKGROUND
Iris resinoid obtained from Iris germanica or Iris pallida rhizomes is widely used in the perfume industry but its chemical composition has not yet been reported. Nevertheless, very active compounds have been identified in iris rhizomes including iridals and isoflavones.
OBJECTIVE
In this
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),
Phytochemical investigations on the methanol extract of Iris germanica resulted in the isolation of a new benzene derivative, 2'-methyl-6'-hydroxy cyclohexenyl-3-methyl-1-acetophenone ether (1). Further, another known benzene derivative, isopenol (2), also afforded two known isoflavones, irisolone
The immunomodulatory activities of two isoflavones, 5,7-dihydroxy-6,4'-dimethoxyisoflavone (irisolidone) (1) and 5,4'-dihydroxy-6,7-methylenedioxyisoflavone (irilone) (2) isolated from Iris germanica (Iridaceae) is reported. Their influence on production of T-lymphocytes (CD4+ and CD8+ cells) and
Six known isoflavones were isolated from the rhizomes of Iris germanica, and were established by UV, MS and NMR techniques as irisolidone (1), irisolidone 7-O-alpha-D-glucoside (1a), irigenin (2), irilone (3), iriflogenin (4), and iriskashmirianin (5). These compounds were examined for their cancer
Iris species are well recognized as wealthy sources of isoflavonoids. In the present study, phytochemical investigation of the rhizomes of Iris germanica (Iridaceae) procure the isolation of two new isoflavonoids namely, 8-hydroxyirilone 5-methyl ether (2) and 8-hydroxyirilone (3), along with eight
