Enteric disposition and recycling of flavonoids and ginkgo flavonoids.
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...
متن کاملAdhesion measurements on the attachment devices of the jumping spider Evarcha arcuata.
The feet of the jumping spider Evarcha arcuata attach to rough substrates using tarsal claws. On smooth surfaces, however, attachment is achieved by means of a claw tuft, the scopula. All eight feet bear a tarsal scopula, which is equipped with setae, these again being covered by numerous setules. In E. arcuata, an estimated 624,000 setules, with a mean contact area of 1.7 x 10(5) nm(2), are pr...
متن کاملFlavonoids of Crotalaria sessiliflora.
Phytochemical investigation of the whole plants of Crotalaria sessiliflora L. led to the isolation of four flavonoids. The structures of these compounds were identified as 2',4',5,7-tetrahydroxyisoflavone (1), 2',4',7-trihydroxyisoflavone (2), 4',7-dihydroxyflavone (3), and isovitexin (4) using spectroscopic analysis. Among these, compounds 2, and 3 have not been reported from Crotalaria specie...
متن کاملAntimicrobial activity of flavonoids.
Flavonoids are ubiquitous in photosynthesising cells and are commonly found in fruit, vegetables, nuts, seeds, stems, flowers, tea, wine, propolis and honey. For centuries, preparations containing these compounds as the principal physiologically active constituents have been used to treat human diseases. Increasingly, this class of natural products is becoming the subject of anti-infective rese...
متن کاملMicrobial Glycosylation of Flavonoids.
Flavonoids constitute a large group of polyphenolic compounds naturally found in plants, which have a wide range of biological activity. Although flavonoids are beneficial to human health, their application is limited by their low bioavailability and poor water-solubility. Therefore, recently there has been a particular interest in glycosylated forms of flavonoids, which usually are better solu...
