Luteolin is a naturally occurring flavonoid compound widely

recognized forits powerful anti-inflammatory, antioxidant, neuroprotective, and

immune-modulating properties. Our Luteolin 98% is a high-purity botanical monomer

Traditional Chinese Medicine as “Huai Mi” .

― which carry inherent allergen risks ― our product is 100% allergen-free, derived

from Sophora japonica buds, making it the safer choice for dietary supplement

formulators targeting global markets with stringent allergen-labeling regulations.

Health Benefits & Scientific Mechanisms

Luteolin is one of the most extensively researched plant flavonoids, with over 120 new

PubMed-indexed studies published in 2024 alone. Its multi-target pharmacological

profile makes it a highly sought-afteringredient across the nutraceutical,

pharmaceutical, and cosmetic industries.

Inhibits NF-κB nucleartranslocation, reducing pro-inflammatory cytokines IL-6 by 62%

and TNF-α significantly. Modulates MAPK pathway p38, JNK, outperforming many

common flavonoids including quercetin.

Potent Antioxidant Activity

ORAC value of 18,200 μmol TE/g ― approximately 8× that of Vitamin C. Activates

Nrf2/HO-1 pathway, upregulating endogenous antioxidant enzymes SOD, GSH −

Px. Reduces lipid peroxidation MDA by 45%.

Neuroprotection & Cognitive Health

Crosses the blood-brain barrier. Suppresses microglial inflammation, reduces iNOS

expression by 55%. Research supports applications in Alzheimer’s, Parkinson’s,

and age-related cognitive decline.

Metabolic Health Support

Activates AMPK pathway, promoting glucose uptake (GLUT4 translocation up 38%).

Reduces fasting blood glucose by 22% in insulin-resistance models. Supports healthylipid profiles.

Immune System Modulation

Enhances Treg cell activity (upregulates Foxp3 expression by 50%). Balances immune

response and reduces autoimmune damage. Acts as a natural mast cell stabilizer.

Skin Health & Anti-Aging

Reduces UVB-induced erythema by 35%. Inhibits MMP-1 activity by 42%, reducing

collagen loss. Inhibits tyrosinase for natural skin-brightening effects. Ideal for anti

aging cosmetic formulations.

product is derived exclusively from Sophora japonica flower buds ― eliminating any

risk of peanut allergen cross-contamination.
