Homoeriodictyol

Different chemical constituents, including flavonoids, have been considered as the active principles of many anti-inflammatory plants. From Baccharis calliprinos Grised and Baccharis rhetinoides Meyer Walp, growing in the Cuyo region of Argentina, Gianello el al. [116] reported the isolation and identification of several anti-inflammatory flavonoids, such as luteolin-7,3 -dimethylether, Fig. (65), homoeriodictyol, Fig. (66) and eriodictyol-3 ,4 -dimethylether, Fig. (67).

In UV-365 nm six yellow, orange-red or green fluorescent flavonoid aglycones are detectable eriodictyol (R, 0.3/T3) followed by a yellow-green zone of chrysoeriodictyol, an orange-red zone of xanthoeriodictyol and the green zone of homoeriodictyol (Rf — 0.5.5/T4).

Chakon synthase, CHS a plant enzyme (formerly called flavanone synthase) catalysing the synthesis of chalcones from one molecule of the CoA ester of a substituted cinnamic add and 3 molecules of malo-nyl-CoA, a key reaction in flavonoid biosynthesis (see Stilbenes, Hg., and Flavonoid, Hg.). Spedfidty varies with the source of the enzyme, e.g. CHS from Tulipa stamens and Cosmos petals forms naringenin, eriodictyol or homoeriodictyol from 4-coumaroyl-...

A recent sensory study of taste modification demonstrated that flavanones of yerba Santa (eriodictyol, homoeriodictyol, and sterubin) had a significant masking effect on the bitter taste of caffeine and other bitter compounds, such as salicin, paracetamol, and quinine. The sodium salt of homoeriodictyol had a dose-dependent bitter masking effect against caffeine and amarogentin. ...
