Product Overview
GH Sea Buckthorn Total Flavonoids Powder (Assay≥10%, Water-Soluble) is a premium botanical extract derived from high-altitude wild small-fruit sea buckthorn (Hippophae rhamnoides L.) leaves natively harvested on the Qinghai Tibetan Plateau. Processed through a 100% water-based extraction process without organic solvent residues, it offers superior bioactivity, exceptional water solubility, and verified antioxidant efficiency for functional food, beverage, and nutraceutical formulations.
Origin Advantage: Qinghai Tibetan Plateau Wild Harvest
Unlike low-altitude cultivated varieties, wild sea buckthorn naturally thriving on the high-altitude Qinghai Tibetan Plateau endures intense UV radiation, extreme temperature fluctuations, and harsh atmospheric conditions. These wild natural stressors trigger the plant to synthesize and accumulate a broader spectrum and higher concentration of highly active free flavonoid glycosides and aglycones.

Research & References
Key Phytochemical Profile (UPLC-PDA-MS Validated):
Ultra-Performance Liquid Chromatography combined with Mass Spectrometry (UPLC-PDA-MS) analysis confirms that GH Sea Buckthorn Total Flavonoids consist predominantly of highly active free flavonoid aglycones[1]:
- Isorhamnetin:Supports cardiovascular integrity and microvascular endothelial health.
- Quercetin:Potent free-radical scavenger and natural anti-inflammatory agent.
- Kaempferol:Promotes cellular resilience and microcirculation efficiency.
- Myricetin:Provides metabolic support and advanced antioxidant defense.
1. High Antioxidant Capacity (NUS-Authorized ORAC Test)
Tested and certified by the National University of Singapore (NUS), GH Sea Buckthorn Total Flavonoids demonstrated exceptional antioxidant activity under the standardized Oxygen Radical Absorbance Capacity assay:
ORAC Hydrophilic Value: 6,740.2 μmol TE/g
Note: The ORAC assay is an internationally recognized standard developed by the USDA to measure peroxyl radical scavenging capacity in botanical raw materials.
2. In Vivo Microcirculation Enhancement (Zebrafish Model)
In a controlled in vivo vascular circulation model using zebrafish embryos, administration of GH Sea Buckthorn Total Flavonoids (at a treatment concentration of 0.29 g/L) demonstrated:
18% increase in blood circulation velocity compared to the blank control group (p < 0.001), validating its efficacy for microvascular flow promotion.
3. Anti-Inflammatory Mechanism
In vivo neutrophil aggregation assays in zebrafish models showed significant suppression of inflammatory cell migration following treatment with Sea Buckthorn flavonoids (0.29 g/L), confirming strong anti-inflammatory bioactivity.
4. Cellular Longevity & Sirt1 Gene Activation
Targeted gene expression analysis revealed that GH Sea Buckthorn Total Flavonoids significantly upregulated Sirt1 mRNA gene expression in living models (0.29 g/L), indicating promising cellular anti-aging and longevity potential.
