Allimacrosides A-E, new steroidal glycosides from Allium macrostemon Bunge.
A new pregnane-type steroidal glycoside (1), two new spirostane-type steroidal glycosides (2, 3), and two new furostane-type steroidal glycosides (4, 5), named allimacrosides A-E, together with four known compounds (6-9) were isolated from a 80% MeOH extract of Allium macrostemon Bunge. The identification and structural elucidation of these compounds were based on their 1D- and 2D-NMR spectra, ...

متن کاملThermal Degradation of Flavonol Glycosides in Noni Leaves During Roasting
Noni leaves have been used for a variety of health benefits for thousands of years. Noni leaf tea, a commercial product made by a roasting process, is attracting more attention due to its potential health benefits. Flavonoids appear to be some of the predominant constituents in noni leaves. As flavonoids exist mostly in the forms of glycosides or polymers, degradation to corresponding metabolit...
متن کاملFlavonol glycosides from Epimedium pubescens.
Five new flavonol glycosides (1, 3, 5-7) were isolated from the aerial parts of Epimedium pubescens Maxim., along with two known compounds, sagittasine C (2) and 4',5-dihydroxyl-8-(3,3-dimethylallyl)-flavonol 3-O-[β-D-xylopyranosyl(1→3)-4-O-acetyl-α-L-rhamnopyranoside]-7-O-β-D-glucopyranoside (4). The structures were elucidated on the basis of their 1D-, 2D-NMR, MS, UV and IR spectra data.
