what is eucommia ulmoides extract used for

Eucommia flavonoids are one of the main active components of Eucommia ulmoides extract, which have the functions of scavenging free radicals, improving immunity, antibacterial and anti-inflammatory, liver protection, and estrogen-like effects. The total flavonoids content in Eucommia ulmoides leaves is the highest, especially in old leaves.

The main physiological activities of Eucommia ulmoides flavonoids

1. Antioxidant effect of flavonoids of Eucommia ulmoides The antioxidant activity of flavonoids is related to the effective phenolic hydroxyl group of the molecular structure. The so-called effective phenolic hydroxyl group refers to the type of phenolic hydroxyl group that flavonoids act as hydrogen donors and stabilize free radical intermediates when scavenging active oxygen, and play an important role in metal complexation. They play an important role in scavenging active oxygen. The phenolic hydroxyl group reacts with free radicals by supplying hydrogen to generate phenoloxy radicals. The phenoloxy radicals are stabilized by the resonance of the aromatic ring large conjugate system to form semiquinone radicals, thereby terminating the free radical chain reaction. The effect can inhibit oxidation. Eucommia flavonoids can also enhance the activity of superoxide dismutase and have a significant protective effect on lipid peroxidation in liver and muscle.

2. Eucommia flavonoids improve immunity. Eucommia flavonoids have varying degrees of regulation on multiple links of the immune system. They can enhance the phagocytic ability of macrophages and the activity of natural killer cells, increase antibody production, and enhance humoral and cellular immunity. Improve disease resistance and self-healing power.
