The exception is one species of Clostridia orbiscindens that can convert the flavonoids luteolin and eriodictyol
(which occur only in a relatively small food group that includes parsley, thyme, celery, and sweet red pepper) to DHPPA.
These citrus bioflavonoids are obtained by aqueous extraction, nebulization and fractionation to produce a product high in hesperidine, eriodictyol
and naringenin, which are then encapsulated in nanospheres to stabilize the actives du ring delivery to the skin.
2000) also showed that [less than or equal to] 25 [micro]M concentrations of various phytochemicals block TCDD-induced transformation of rat liver cytosolic AhR, and these include chrysin, baicalein, apigenin, luteolin, tangeretin, galangin, kaempferol, fisetin, morin, quercetin, myricetin, tamarixetin, isorhamnetin, naringenin, eriodictyol
, and hesperitin.

(derivative 77 in Table 1) induces apoptosis in HL-60 cells (Ogata et al.
The flavonoid and chalcone glycosides were not active up to 50 p,M, whereas catechol and eriodictyol at the same concentration showed a significant reduction of ICAM-1 expression to 50% of control.
Among the other isolated phenols only the flavanone aglycone eriodictyol (18) showed significant in vitro activity.

Besides salicin, willow bark has been shown to contain flavonoids, such as glycosides of naringenin, isosalipurpuroside or eriodictyol
