Quantitative determination of five glucosyloxybenzyl 2-isobutylmalates in the tubers of Gymnadenia conopsea and Coeloglossum viride var. bracteatum by HPLC.

30 Aug 2009 Glucosyloxybenzyl 2-isobutylmalates are one group of important active constituents in the tubers of Gymnadenia conopsea R. Br. and Coeloglossum viride (L.) Hartm. var. bracteatum (Willd.). For the purpose of quality evaluation of these two Chinese ... Read more...

Inhibitors of osteoclast formation from rhizomes of Cibotium barometz.

30 Aug 2009 Eight compounds (1-8) were isolated from a methanol extract of Cibotium barometz rhizomes including two new furan derivatives, cibotiumbarosides A (1) and B (2), and a new glycoglycerolipid, cibotiglycerol (4). Their structures were elucidated by ... Read more...

Quantitation of chafurosides A and B in tea leaves and isolation of prechafurosides A and B from oolong tea leaves.

10 Aug 2009 A procedure was developed for the quantitative determination of chafuroside A, a flavone C-glycoside with potent anti-inflammatory activity, and its regioisomer chafuroside B, as well as isovitexin and vitexin, by selected reaction monitoring liquid ... Read more...

Technical information about 'Glycosides'

Definition: Any compound that contains a constituent sugar, in which the hydroxyl group attached to the first carbon is substituted by an alcoholic, phenolic, or other group. They are named specifically for the sugar contained, such as glucoside (glucose), pentoside (pentose), fructoside (fructose), etc. Upon hydrolysis, a sugar and nonsugar component (aglycone) are formed. (From Dorland, 28th ed; From Miall's Dictionary of Chemistry, 5th ed)
