Hesperidin CAS 520-26-3 Powder 90%,95%
What is Hesperidin?
Hesperidin is a bioflavonoid widely found in citrus fruits and a key component of vitamin P, which is essential for the human body. Pure hesperidin appears as white, needle-shaped crystals with a typical dihydroflavonoid structure.
In terms of physiological functions, hesperidin exhibits significant synergistic effects with vitamin C. It can enhance vitamin C activity, reduce vascular permeability, and improve vascular elasticity, thereby contributing to cardiovascular health. Studies have shown that this ingredient also possesses various biological activities, including antioxidant, anti-allergic, blood pressure-lowering, and cholesterol-regulating properties.
In the food industry, hesperidin can be hydrogenated to produce a natural sweetener, dihydrochalcone, which can be up to 1,000 times sweeter than sucrose and can be used as a functional ingredient. Furthermore, it exhibits broad-spectrum antibacterial activity against a variety of common food contaminants, such as Bacillus subtilis and Salmonella typhimurium. This property makes it valuable for applications in food preservation and processing.
Pharmacological activity and whitening mechanism of hesperidin
I. Pharmacological Activity Studies
Hesperidin, a natural flavonoid, has demonstrated significant pharmacological value in medicine. It is a raw material for the treatment of hypertension and myocardial infarction and a key component of the traditional Chinese medicine "Maitong." Studies have shown that hesperidin exhibits multiple benefits, including anti-lipid oxidation, free radical scavenging, anti-inflammatory, antiviral, and antibacterial properties. Long-term use can help delay aging. This ingredient also demonstrates potential in sports medicine and nutrition, and its broad range of biological activities warrants further systematic investigation.
II. Whitening Mechanism
In studies of its whitening mechanism, hesperidin has been shown to significantly inhibit tyrosinase activity and reduce melanin content in primary human melanocytes in a dose-dependent manner. Animal studies have shown that topical application of a 1%-3% hesperidin cream for three weeks effectively reduces UVB-induced skin hyperpigmentation in guinea pigs without causing adverse reactions such as redness or scaling.
Molecular mechanistic studies have revealed that hesperidin downregulates the expression of the key transcription factor MITF, thereby inhibiting the expression of downstream melanin synthesis-related proteins (tyrosinase, TRP-1, and TRP-2), ultimately achieving multiple regulatory effects on melanin synthesis.
In addition, hesperidin and its aglycone hesperetin exhibit significant antioxidant capacity, scavenging DPPH and hydroxyl radicals in a concentration-dependent manner and effectively inhibiting the formation of lipid peroxides in the body. These antioxidant properties also indirectly inhibit the melanin production pathway.
What are the benefits?
1. Improves Skin Quality
As a natural flavonoid glycoside, hesperidin possesses excellent antioxidant properties, helping to scavenge free radicals in the skin and reduce melanin deposition, thereby improving dull skin tone and achieving a brightening and whitening effect. It also promotes skin metabolism and local blood circulation, improving dryness, roughness, and enlarged pores. Moderate use can enhance skin hydration and overall skin texture.
2. Cholesterol Regulators
Hesperidin promotes cholesterol metabolism and effectively lowers low-density lipoprotein (LDL) cholesterol levels in the blood, contributing to cardiovascular health and the prevention of related diseases.
3. Anti-inflammatory Effects
This ingredient exhibits anti-inflammatory properties, alleviating inflammatory reactions and related symptoms. It is valuable in the treatment of chronic inflammatory conditions such as arthritis and asthma.
4. Improves Digestion
Hesperidin enhances intestinal motility and promotes gastrointestinal secretions, helping to improve food digestion and nutrient absorption.
Application direction
In the food industry, hesperidin, a naturally derived antioxidant, effectively extends the shelf life of various foods. It is also used as a functional additive to enhance food taste and nutritional value. With growing consumer demand for health and wellness, health foods centered around their antioxidant and anti-inflammatory properties are increasingly popular. Hesperidin-fortified products are now available in a variety of forms, including functional beverages, nutritional supplements, and healthy snacks.
In the cosmetics sector, hesperidin, due to its proven antioxidant and skin-improving properties, has become a key active ingredient in skincare formulations. This ingredient and its derivatives are widely added to various skincare and beauty products to help improve skin condition and delay signs of aging.
