From the arial parts of Bassia muricata, two acylated flavonoid glycosides quercetin-3-O-(6"-caffeoyl)-sophoroside and quercetin-3-O-(6"-feruloyl)-sophoroside have been isolated together with two known flavonoid glycosides quercetin-3-O-sophoroside and quercetin-3,7-O-beta-diglucopyranoside, as well as four known triterpenoidal saponins, oleanolic acid-3-O-beta-glucopyranoside, chikusetsusaponi...

Two new glycosides, chrysoeriol-7-O-(2"-O-beta-D-mannopyranosyl)-beta-D-allopyranos ide and rhamnetin-3-O-(2"-O-beta-D-mannopyranosyl)-beta-D-allopyranosid e, were isolated from the seeds of Cassia alata. The structures were established on the basis of chemical evidence and spectroscopic methods, especially NMR.

The MeOH extract from dried whole Botrychium ternatum plants yielded 33 compounds, including seventeen new flavonoid glycosides and sixteen known compounds. The structures of new compounds were established using NMR spectroscopic analysis and chemical evidence.

A comprehensive survey of the leaf flavonoids of the genus Lavandula and the related Sabaudia group was carried out using two-dimensional paper chromatography and high-performance liquid chromatography. The flavonoid patterns obtained were found to be systematically informative at the infrageneric level. Three main groupings were identified: the first containing sections Lavandula, Dentata and ...

The total phenolic and flavonoid content of extracts from peel of kumquat were higher than those from pulp, and those extracted from immature kumquat were higher than those from mature kumquat. The highest levels of phenolic and flavonoid content were obtained in hot water extracts. The flavonoids of kumquat extracted from hot water were mainly soluble conjugated compounds, including C-glycosid...

OBJECTIVE The objective of this study was to determine the intestinal and microbial disposition of flavonoids and how these disposition processes affect their enteric recycling. DESIGN Studies were performed using a perfused rat intestinal model or using enrichment cultures and a pure isolate of Enterococcus avium (LY1). RESULTS In the rat intestine, aglycones, such as quercetin and apigeni...
