What is Pure Quercetin Powder?
Pure Quercetin Powder (3,3',4',5,7-pentahydroxyflavonoid). It is a natural flavonoid with strong biological activity. It is widely found in the flowers, stems, leaves, fruits, and seeds of various fruits and vegetables and various medicinal plants. Quercetin mostly exists in the form of glycosides, such as quercetin, rutin, hypericin, etc.
quercetin pure and its glycoside derivatives are absorbed by intestinal epithelial cells after being hydrolyzed into aglycones in the small intestine. After uronic activation and O-methylation, it is transported from the hepatic portal vein to the liver, further metabolized in the liver, and released into the blood. Quercetin has many functions such as antioxidant, anti-inflammatory, and improving intestinal flora.

What are the benefits of Pure Quercetin Powder?
pure quercetin has various biological effects such as antioxidant, anti-inflammatory, antibacterial, antiviral, anti-aging, lowering blood pressure, lowering blood sugar, regulating the structure of intestinal flora, and protecting neurons and the liver. Among them, the antioxidant, anti-inflammatory, antibacterial and antiviral effects are the most widely used in the field of animal production.
1. Antioxidant effect
Quercetin contains 5 phenolic hydroxyl groups and has a strong antioxidant capacity. In addition to directly complexing free radicals, quercetin can also play an antioxidant role by activating the antioxidant system.
2. Anti-inflammatory effect
Quercetin can regulate the expression of immune-related factors and is a good natural anti-inflammatory chemical. In vivo and in vitro tests, quercetin showed anti-inflammatory activity, which can inhibit the production of inflammatory cytokines (TNF-10), interleukin (IL)-1β, IL-6, etc.
3. Antibacterial and antiviral effects
Pure Quercetin has antibacterial and antiviral effects without developing drug resistance. Quercetin can inhibit the total bacterial count of harmful flora such as Escherichia coli, Staphylococcus aureus, Salmonella, Pseudomonas aeruginosa, Bacillus subtilis, Streptococcus faecalis, and Enterococcus. However, different doses of quercetin are required to inhibit different flora. It mainly exerts its antibacterial effect by destroying the bacterial cell membrane and causing the content to leak.
Quercetin has a good antiviral effect. 12 μmol/L quercetin can significantly inhibit the F and G proteins of respiratory syncytial virus (RSV) in the supernatant of Vero cells, and the virus inhibition rate can reach 60%.
Application of Pure Quercetin Powder in Animal Production:
1. Improve animal production performance
In the field of animal husbandry, the improvement of production performance is mainly reflected in the improvement of feed conversion rate and meat and egg quality. quercetin pure can effectively improve the performance of poultry. The results showed that different concentrations of quercetin could improve the meat quality of chicken breast and leg muscles.
Different quercetin concentrations had different effects on various indicators of chicken. The best results were obtained when the concentration of quercetin in the feed was 4 g/kg. In laying hen production, quercetin can improve the production performance and egg quality of laying hens in the late laying period. Significantly reduce the feed-to-egg ratio, increase the protein content in the egg yolk, reduce the cholesterol content in the egg yolk, and improve the egg quality of the egg.
2. Regulate animal immunity
Adding quercetin to the feed can enhance the immunity of animals. Quercetin promotes spleen,
Bursa and thymus development. Induce macrophages to secrete cytokines and enhance the phagocytic function of macrophages. In addition to regulating immune cytokines, quercetin. It also increases immune resistance by modulating extracellular traps. Studies have shown that quercetin can induce the formation and release of chicken heterophilic extracellular traps (HETs) to capture Candida albicans.
3. Improve animal gut health
200 mg/kg quercetin can promote the expression and nuclear entry of intestinal Nrf2, relieve the inhibition of LPS on the mRNA and protein expression of Nrf2 downstream genes SOD, NQO1, and HO-1; At the same time, it can promote the phosphorylation of p38, ERK, and JNK in the MAPK pathway. This indicates that quercetin may alleviate the intestinal injury of broilers caused by LPS through the MAPK/Nrf2 pathway. In addition, quercetin reduced the abundance of Pseudomonas aeruginosa, Helicobacter pylori, Staphylococcus aureus, Escherichia coli, Clostridium perfringens, and Campylobacter jejuni in the cecum. Increased abundance of Lactobacillus and Enterococcus faecalis.
