Genistin has antioxidant activities; however, its insolubility in water often limits its biological availability in vivo. Using a novel transglycosylation process, the solubility of genistin glycosides was increased 1000 to 10000-fold, but it was not known whether these modified genistin glycosides maintained antioxidant activity. We found that both genistin and its glycosides similarly up-regu...

Four new triterpene glycosides: one cycloartane-type glycoside and three azukisapogenol glycosides were isolated together with one known oleanene bisdesmoside from the Mongolian natural medicine, Oxytropis myriophylla.

The pod of Cassia fistula Linn. has been used as a laxative drug in Thai traditional medicine for a long time. The pods and leaves contain anthraquinone aglycones and anthraquinone glycosides which are the active laxative form, while rhein is a major component. The degree of laxative potency is depended on the content of anthraquinone glycosides. This study determined the content of total anthr...

Triisobutylaluminium-promoted rearrangement of unsaturated glycosides containing electron-donating aglycons, such as C-aryl glycosides, provides direct access to highly functionalised cyclohexane derivatives.

'fhis review article provides a comprehensive description of various studies, carried out on Thevetia neriifoiia which is a source of several cardioactive glycosides, since early 20th century. The article provides an overview of various other medicinal herbs containing cardiac glycosides and discusses in depth various com[pounds isolated so far from this medicinal herb and their pharmacology. A...

Twenty-nine new oxypregnane glycosides were obtained along with two known cardenolides, frugoside and gofruside, and three known 12-O-acylated pregnane glycosides from the roots of Asclepias incarnata L. (Asclepiadaceae). By detailed studies of the 1H- and 13C-NMR spectra, the structures were determined to be tri- to penta glycosides of isolineolon, 12-O-acetyllineolon, ikemagenin, 12-O-benzoyl...

Puerarin is an isoflavone derived from Kudzu roots and has antioxidant and hypocholesterolemic effects; however, its insolubility often limits its biological availability in vivo. Using a novel transglycosylation process, the solubility of puerarin glycosides was increased >100-fold, but it was not known whether these modified puerarin glycosides maintained biological activities. We found that ...
