Flavonoids are a diverse group of plant compounds with antioxidant properties, found in various fruits, vegetables, and other plant materials that may be included in equine diets. In horses, flavonoids are investigated for their potential effects on health and performance, including their impact on inflammation, oxidative stress, and immune function. Research explores how these compounds may influence equine physiology, particularly in relation to exercise, recovery, and overall well-being. This page compiles peer-reviewed research studies and scholarly articles that examine the sources, metabolism, and potential effects of flavonoids in horses, providing insights into their role in equine nutrition and health management.

(ginkgo extract) when used as a sensory additive in feed for horses, dogs, cats, rabbits and guinea pigs. Ginkgo extract contains ≥ 24% total flavonoids, ≥ 6% total terpene lactones and ≤ 1 mg/kg ginkgolic acids. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that ginkgo extract is safe for the target species at the following concentrations in complete fee...

(anise tincture) when used as a sensory additive in feed and water for drinking for all animal species. The product is a â– â– â– â– â– solution, with a dry matter content of approximately 1.6%. The product contained on average 0.0414% polyphenols (of which 0.0144% were flavonoids), 0.0009% anisaldehyde, 0.0003% anethole. Estragole (≤ 1.2 mg/kg) was detected in the additive. The estimated maximum content of furocoumarins was 8.2â...

(gentian tincture). It is intended to be used as a sensory additive for all animal species. The product is a water/ethanol solution, with a dry matter content of approximately 4.3% and it contains on average 0.0836% polyphenols (of which 0.0463% are flavonoids and 0.0027% xanthones) and 0.0022% gentiopicroside. The additive is intended for use in complete feed or drinking water up to a maximum level of 50 mg tincture/kg for all animal species, except ho...

Song K, Yang GM, Han J, Gil M, Dayem AA, Kim K, Lim KM, Kang GH, Kim S, Jang SB, Vellingiri B, Cho SG.Flavonoids form the largest group of plant phenols and have various biological and pharmacological activities. In this study, we investigated the effect of a flavonoid, 3, 4'-dihydroxyflavone (3, 4'-DHF) on osteogenic differentiation of equine adipose-derived stromal cells (eADSCs). Unassigned: Treatment of 3, 4'-DHF led to increased osteogenic differentiation of eADSCs by increasing phosphorylation of ERK and modulating Reactive Oxygen Species (ROS) generation. Although PD98059, an ERK inhibitor, suppressed osteogenic differentiation, another ERK inhibitor, U0126, apparently increased osteoge...
Bampidis V, Azimonti G, Bastos ML, Christensen H, Fašmon Durjava M, Kouba M, López-Alonso M, López Puente S, Marcon F, Mayo B, Pechová A....The tincture derived from L. (great mullein tincture) is intended to be used as a sensory additive in feed for all animal species. The product is a water/ethanol solution, with a dry matter content of ˜ 2.8% and contains on average 0.216% polyphenols including 0.093% flavonoids. According to a previous assessment, the additive was not characterised in full and about 82% of the dry matter fraction remained uncharacterised (representing 2.26% of the tincture). There was also uncertainty on the potential presence of iridoid glycosides in the tincture. Therefore, the Panel on Additives and Prod...
Dedar RK, Kumar N, Narnaware SD, Tripathi BN.Wound healing in horses is complicated by the excessive growth of granulation tissue, commonly known as proud flesh and is similar to keloids in human beings. At present, there is no satisfactory treatment for proud flesh in horses. In this study, we, for the first time, demonstrated that leaf extract of Aerva javanica suppresses excessive growth of granulation tissue in horses. Many plant flavonoids are claimed to have antiproliferative properties. Kaempferol is a natural flavonoid containing 3-hydroxy flavone backbone found in many plants in its aglycone form and attached with various sugars...

In addition to (•)Trp and TyrO(•) radical production, ferrous iron liberation and Ft synthesis stimulation, site-specific oxidation reactions are induced leading to toxic iron accumulation in organs with high Ft content, for example, liver and brain.
