چکیده

Phytochemical investigation of the rhizomes of Iris kashmiriana (Iridaceae) led to the isolation of three isoflavones characterized by 1D and 2D NMR, IR, UV, and MS as 4'-hydroxy-8-methoxy-6,7-methylenedioxyisoflavone (isonigricin, 1), 5,6-dihydroxy-4',7-dimethoxyisoflavone (isoirisolidone, 2), and 5,7-dihydroxy-4',6-dimethoxyisoflavone (irisolidone, 3). Compound 1 is a new isoflavone, while 2 is reported for the first time from a natural source.

Isoflavonoid 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.

[Analysis of isoflavones in Belamcanda chinensis (L.)DC. and Iris tectorum Maxim by square wave voltammetry].

Three isoflavones: irigenin, tectorigenin and tectoridin in Belamcanda chinensis (L.)DC. and Iris tectorum Maxim were determined by square wave voltammetry. At the potential of -1.34 V (vs Ag/AgCl) the isoflavones gave well-defined peaks in the buffer solutions of pH3-5. An excellent linear relationship was obtained between the peak current and concentration. The method can be used to analyze s...

Iris localization by means of adaptive thresholding and Circular Hough Transform

In this paper, a new iris localization method for mobile devices is presented. Our system uses both intensity and saturation threshold on the captured eye images to determine iris boundary and sclera area, respectively. Estimated iris boundary pixels which have been placed outside the sclera will be removed. The remaining pixels are mainly the boundary of iris inside the sclera. Then, circular ...
