Smoke tree extract fisetin
product benefits
Our smoke tree extract (fisetin) is derived from the stem bark and twigs of *Cotinus coggygria* (Anacardiaceae). It is produced through food-grade ethanol extraction, low-temperature concentration, and recrystallization purification. The final product is a fine powder ranging in color from bright yellow to yellow-green; it is odorless and possesses excellent flowability. Our raw materials originate from Shaanxi and Henan provinces in China; they are free from pesticide residues and heavy metal contamination, and we ensure a stable year-round supply. Our proximity to the production hub allows us to offer highly competitive pricing.
We supply the following specifications:
Fisetin 50% / 80% / 98% (Peak normalization method)/(External standard method)
Please note that pricing varies based on the testing method; for the same concentration level, the price using the external standard method is higher than that using the peak normalization method.
Third-party testing report
Our lab checks each batch of product to make sure it is really good and meets all requirements.
Before we ship, we can also send some samples to another lab for testing.
You can choose a lab, like Eurofins, SGS, AIE, or any other lab you prefer.
Product benefits
Potent Antioxidant: It has four hydroxyl groups that help it fight superoxide anions and hydroxyl radicals. The fisetin molecule also prevents lipid peroxidation. The antioxidant activity of the molecule is three times that of vitamin C and two times that of vitamin E.
Anti-inflammatory: It blocks the inflammatory factor NF-κB. The fisetin molecule reduces the release of pro-inflammatory cytokines such as IL-6 and TNF-α. This helps alleviate inflammation.
Anti-aging: The fisetin molecule eliminates skin fibroblasts. It inhibits the senescence-associated secretory phenotype. The fisetin molecule promotes collagen synthesis. Reduces wrinkles. It also improves skin laxity.
Neuroprotection: It crosses the blood-brain barrier. Boosts brain-derived neurotrophic factor levels. The fisetin molecule reduces β-amyloid deposition and improves memory. It delays decline.
Metabolic Regulation: It activates the AMPK pathway. Promotes glucose uptake. The fisetin molecule reduces insulin resistance. Inhibits adipocyte differentiation. This helps with weight management.
Skin Health: It inhibits tyrosinase activity. Reduces melanin production. The molecule repairs UV-induced damage and enhances skin elasticity and radiance.

fAQ
Q: What’s the difference between fisetin and Vitamin C?
A: Fisetin is a natural flavonoid offering a triple-action profile: antioxidant, anti-inflammatory, and senescent cell-clearing properties. It boasts higher potency (three times that of vitamin C), a unique mechanism of action, and superior anti-aging effects.
Q: How should a customer choose between 98% and 50% purity?
A: 98%: Ideal for premium supplements, anti-aging skincare, and pharmaceutical R&D; requires lower dosage, offers precise efficacy, and commands higher added value.
50%: Suitable for functional foods, standard beverages, and cost-sensitive formulations; offers excellent cost-performance and superior solubility.
Q: What is the solubility of fisetin, and how can its bioavailability be improved?
A: Fisetin is sparingly soluble in water (≤0.1 g/L) but readily soluble in ethanol, propylene glycol, and DMSO. Water solubility and bioavailability can be enhanced through technologies such as liposomal encapsulation, nano-emulsification, and cyclodextrin inclusion.
Q: Do you provide samples for testing?
A: Yes, free samples (10–50g) are available (shipping costs collected). Samples come with a Certificate of Analysis (COA) and are delivered within 3–5 days; customers are welcome to conduct their own testing and verification.
Q: What is the product's shelf life?
A: 24 months (unopened).
Q: How should it be stored?
A: Store in a sealed container in a cool, dry place (≤25°C).
