Functions of Quercetin from Sophora Japonica Bud Extract

1. Antioxidant Activity
   • Quercetin is a powerful antioxidant. It can scavenge free radicals such as superoxide anions, hydroxyl radicals, and peroxyl radicals. These free radicals are highly reactive molecules that can cause damage to cellular components like DNA, proteins, and lipids. By neutralizing these free radicals, quercetin helps to protect cells from oxidative stress and reduces the risk of various diseases related to oxidative damage, including cancer, cardiovascular diseases, and neurodegenerative disorders. For example, in vitro studies have shown that quercetin can effectively prevent the oxidation of low - density lipoprotein (LDL), which is a key factor in the development of atherosclerosis.
2. Anti - inflammatory Effects
   • It has significant anti - inflammatory properties. Quercetin can inhibit the production and release of pro - inflammatory cytokines such as interleukin - 1β (IL - 1β), interleukin - 6 (IL - 6), and tumor necrosis factor - α (TNF - α). These cytokines play a crucial role in the inflammatory response and are involved in many chronic inflammatory diseases like arthritis and inflammatory bowel disease. Additionally, quercetin can suppress the activation of nuclear factor - κB (NF - κB), a transcription factor that regulates the expression of many inflammatory genes. In animal models of inflammation, quercetin treatment has been shown to reduce tissue inflammation and swelling.
3. Cardiovascular Protection
   • Quercetin is beneficial for cardiovascular health. It can help to lower blood pressure by relaxing blood vessels. This is achieved through its effect on endothelial cells, where it promotes the production of nitric oxide, a vasodilator. Moreover, quercetin can reduce platelet aggregation, which is an important step in the formation of blood clots. By preventing excessive platelet aggregation, it decreases the risk of thrombosis and related cardiovascular events such as heart attacks and strokes. In some clinical trials, quercetin supplementation has been associated with improvements in blood lipid profiles, including a reduction in triglycerides and LDL - cholesterol levels.
4. Anticancer Potential
   • There is growing evidence suggesting that quercetin may have anticancer properties. It can interfere with different stages of cancer cell growth and proliferation. For example, quercetin can induce cell cycle arrest in cancer cells, preventing them from dividing and multiplying. It can also trigger apoptosis (programmed cell death) in cancer cells through various mechanisms, such as activating caspases and modulating the expression of apoptotic - related genes. Additionally, quercetin may have the ability to inhibit the metastasis of cancer cells by suppressing their migratory and invasive abilities. However, it's important to note that while these findings are promising, more research is needed to fully understand its role in cancer treatment and prevention.

 

Application Ranges of Quercetin from Sophora Japonica Bud Extract

 

1. Nutraceuticals and Dietary Supplements
   • Quercetin is widely used in the nutraceutical industry. It is often formulated into dietary supplements such as capsules, tablets, and powders. These supplements are designed to provide antioxidant and anti - inflammatory benefits to consumers. People who are concerned about oxidative stress - related health issues, such as those with a high - stress lifestyle or a family history of chronic diseases, may take quercetin supplements to support their overall health. The recommended daily dosage of quercetin varies depending on the product and the intended use, but it generally ranges from 500 to 1000 mg per day.
2. Pharmaceutical Industry
   • In the pharmaceutical field, quercetin is being investigated for its potential use in the treatment of various diseases. For example, its anti - inflammatory and antioxidant properties make it a candidate for the development of drugs for inflammatory diseases and cardiovascular disorders. Some pharmaceutical companies are researching ways to enhance the bioavailability of quercetin to improve its therapeutic efficacy. Additionally, quercetin's possible anticancer effects have led to studies exploring its use in combination with existing cancer therapies to enhance treatment outcomes and reduce side effects.
3. Cosmetics and Skincare Products
   • Due to its antioxidant and anti - inflammatory characteristics, quercetin is also used in cosmetics and skincare products. It can be found in creams, lotions, and serums. In skincare, quercetin helps to protect the skin from environmental damage caused by factors such as UV radiation and pollution. By reducing oxidative stress and inflammation on the skin, it can improve skin tone, reduce the appearance of wrinkles, and enhance the overall health and appearance of the skin. For example, quercetin - containing creams are often marketed for their anti - aging benefits
