Product Description

Overview

Luteolin (3',4',5,7-tetrahydroxyflavone, CAS 491-70-3) is a naturally occurring flavone found in many edible and medicinal plants. GreeneryBio supplies pharmaceutical-grade Luteolin extracted from GAP-certified botanical sources — primarily Chrysanthemum morifolium (chrysanthemum), Perilla frutescens (perilla), and Sophora japonica (Japanese pagoda) — with full traceability and strict freedom from heavy metals, pesticide residues, and microbial contaminants.

Our material is available in three HPLC-verified purity grades:

  • Standard: ≥95.0%
  • High Purity: ≥98.0%
  • Premium: ≥99.5% (suitable for pharmaceutical and clinical research)

All batches comply with USP/EP analytical methods and ICH Q3C solvent-residue limits.

Raw Material & Extraction

We employ a green, multi-stage purification technology:

  • Pretreatment — low-temperature drying and micronization of botanical material to maximize extraction efficiency.
  • Extraction — ultrasound-assisted ethanol extraction (300 W, 40 min) or supercritical CO₂ extraction (35 MPa, 45 °C).
  • Purification — solvent defatting, AB-8 macroporous-resin adsorption, preparative HPLC on C18 reverse-phase column, and recrystallization in a methanol-water system.
  • Final processing — vacuum drying and sterile packaging yield a stable crystalline product.

This process minimizes structural analogs (apigenin, kaempferol) below 0.5% in our High Purity grade, eliminating a common cross-reactivity headache in HPLC assays.

Health Benefits & Mechanisms

Potent anti-inflammatory activity

  • Inhibits NF-κB, MAPK (JNK/p38), and STAT3 pathways
  • Reduces TNF-α, IL-6, and NO production in activated macrophages
  • Suppresses mast cell degranulation and histamine release, useful in anti-allergy formulations

Antioxidant defense

  • Scavenges DPPH, ABTS, and hydroxyl radicals (DPPH IC₅₀ ≈ 15.3 μM)
  • Activates the Nrf2 / ARE / HO-1 pathway, upregulating endogenous antioxidant enzymes
  • Protects cells from oxidative DNA damage

Neuroprotection

  • Mitigates β-amyloid aggregation and tau hyperphosphorylation in cognitive-health models

Cardiovascular support

  • Improves lipid metabolism via the retinoic-acid–PPAR axis
  • Inhibits vascular inflammation and oxidative stress
  • Reduces foam-cell formation, contributing to anti-atherosclerotic activity

Additional benefits

  • Uric acid lowering through xanthine oxidase inhibition
  • Skin — soothes sensitive skin, reduces redness, supports skin wellness formulations

Applications

Nutraceuticals & dietary supplements

  • Anti-inflammatory and joint-health capsules/tablets
  • Cardiovascular blends with resveratrol and omega-3
  • Cognitive-health stacks

Cosmetics & personal care

  • Sensitive-skin creams and serums (reduces redness)
  • topical formulations leveraging antioxidant and collagen-protecting effects
  • Brightening products (inhibits melanin synthesis)

Pharmaceutical R&D

  • Anti-inflammatory drug candidates for chronic inflammatory disease
  • Respiratory therapies under investigation

Functional foods & beverages

  • Health drinks, herbal teas, and fortified snacks for daily antioxidant support
