Puerarin (daidzein-8-C-glucoside) is the major bioactive isoflavone of kudzu root (the root of Pueraria lobata). Its metabolic fate, however, is not well-known. In this study, a sensitive and specific LC-ESI-MS/MS method for the determination of puerarin and its metabolites daidzein, dihydrodaidzein, and equol was developed for their analysis in biological samples. Two new metabolites of puerar...

The Gladiolus is the largest genus in the family Iridaceae that contains many bulbous plants from southern Africa. Flower coloration varies from white, yellow, pink, red to purple. Some anthocyanins have been isolated as flower pigments, but other flavonoids are hardly reported. In this survey, the anthocyanins and other flavonoids of the bluish cultivar, G. x grandiflora ‘Ariake’ were isolated...

The discovery of an acylated steryl glucoside in plant tissue in 1964 (13) raised the number of known forms of sterols in plants to four. These are the free sterols, sterol esters, steryl glycosides, and acylated steryl glycosides. Kiribuchi et al. (12) analyzed the sterol content of soybean and found that sterol ester was present in very small amount and that the sterol was mostly in the form ...

The biocatalytic synthesis of xylooligosaccharides of daidzein was investigated using cultured cells of Catharanthus roseus and Aspergillus sp. β-xylosidase. The cultured cells of C. roseus converted daidzein into its 4'-O-β-glucoside, 7-O-β-glucoside, and 7-O-β-primeveroside, which was a new compound. The 7-O-β-primeveroside of daidzein was further xylosylated by Aspergillus sp. β-xylosidase t...

Background and objectives:Lallemantia iberica (Lamiaceae) is a medicinal plant distributed in different parts of Iran. This research, has evaluated the phytochemical constituents and antioxidant activity of the aerial parts of the plant. Methods: Different chromatographic methods such as column chromatographies using Silica gel (normal and revers...

Two stilbene glucosides, oxyresveratrol 2-O-beta-glucopyranoside and resveratrol 3,4'-O,O'-di-beta-D-glucopyranoside, and a 2-arylbenzofuran glucoside, schoenoside, were isolated from the rhizomes of Schoenocaulon officinale, along with five known compounds, oxyresveratrol 3'-O-beta-D-glucopyranoside, oxyresveratrol, resveratrol 3-O-beta-D-glucopyranoside, mulberroside A and moracin M 3'-O-beta...

Increasing findings devote to searching for natural active compositions as additives ameliorate health status. Anthocyanin, water-soluble pigment, has been concerned due its favorable antioxidant activity. In this study, we purified anthocyanin from Dioscorea alata L., identified compounds, and evaluated properties. The results indicated that the purity of increased 39.59 ± 1.56%, 60.18 1.97%, ...
