Applications
1. Pharmaceuticals & Dietary Supplements
Quercetin丨CAS 117-39-5 is widely used as an antioxidant and anti-inflammatory agent in nutraceuticals and supplements.
Found in many immune-boosting, cardiovascular health, and anti-allergy formulations.
Investigated for potential antiviral, anticancer, and neuroprotective activities.
2. Food & Beverage Industry
Employed as a natural antioxidant and functional food additive to enhance shelf life and nutritional value.
Naturally present in apples, onions, berries, red wine, and tea, and can be fortified into juices, snacks, or health drinks.
3. Cosmetics and Skincare
Incorporated into anti-aging, anti-acne, and UV-protection skincare products for its antioxidant and anti-inflammatory effects.
Helps reduce redness, oxidative stress, and hyperpigmentation in topical formulations.
4. Research and Biotechnology
Extensively studied for its ability to modulate cell signaling pathways, such as NF-κB, PI3K/AKT, and MAPK.
Used in biomedical research related to oxidative stress, inflammation, and metabolic disorders.
Benefits
1. Strong Antioxidant Activity
Neutralizes free radicals and reactive oxygen species (ROS), helping to protect cells from oxidative damage.
Enhances cellular defense mechanisms and may slow down age-related degradation.
2. Anti-inflammatory Properties
Inhibits the release of pro-inflammatory mediators like histamine, leukotrienes, and cytokines.
Supports conditions such as arthritis, asthma, and dermatitis.
3. Immune Support and Antiviral Potential
Enhances immune system activity by modulating immune cell responses.
Shown in studies to inhibit viral replication (including influenza, rhinoviruses, and some coronaviruses) in vitro.
4. Cardiovascular Health
Improves endothelial function, reduces LDL oxidation, and supports healthy blood pressure levels.
May help prevent atherosclerosis by reducing plaque formation.
5. Anti-Cancer Potential
Demonstrates cytotoxic effects on cancer cells through induction of apoptosis and inhibition of angiogenesis.
Research ongoing for use in colon, breast, prostate, and lung cancer therapies.
6. Neuroprotective Effects
Crosses the blood-brain barrier and may protect neurons from oxidative stress and inflammation.
Studied for use in Alzheimer's, Parkinson's, and cognitive decline prevention.
7. Antiallergic and Antihistamine Properties
Reduces allergic symptoms by stabilizing mast cells and preventing histamine release.
Summary
Quercetin丨CAS 117-39-5 is a naturally occurring plant flavonoid valued for its antioxidant, anti-inflammatory, immune-supporting, and cardioprotective properties. It is widely used in dietary supplements, cosmetics, functional foods, and pharmaceutical research, offering a broad range of health benefits with minimal toxicity. Its versatility and effectiveness have made it a key ingredient in modern nutraceutical and health-focused industries.
