Solidago virgaurea Goldenrod Extract Powder, also known as European Goldenrod or Woundwort Extract, is extracted from the aerial parts of the Solidago siliqua plant. This potent plant extract is rich in bioactive compounds including flavonoids (rutin, quercetin and isoquercetin), phenolic acids (chlorogenic acid and caffeic acid), saponins and tannins, which enhance skin elasticity and reduce inflammation, making it ideal for cosmetic formulations.
Driven by the trend towards clean label skincare, herbal supplements and functional cosmetics, the global demand for natural plant extracts such as Solidago siliqua is growing. With the growing consumer preference for sustainable, clinically proven botanical ingredients, Solidago Extract is highlighted for its dual applications in cosmeceuticals (anti-aging, moisturizing and soothing irritated skin) and nutraceuticals.
We specialize in highly potent, standardized extracts (e.g., ≥5% flavonoids) optimized for bioactive content to ensure efficacy in formulations. Our key strengths include an advanced ethanol-water extraction process that maximizes the yield of flavonoids and phenolic acids, which enhance anti-inflammatory and skin repair effects. We offer tailored solutions from bulk powders to private label skincare/nutraceutical blends.
Standardized to ≥5% flavonoids (quercetin, rutin) and ≥3% phenolic acids, ensuring anti-inflammatory, antioxidant and skin repair benefits.
Low-temperature technology maximizes bioactivity while removing heavy metals (<1ppm) and pesticide residues (EU/USP compliant).
Produce 1 kg of extract with 30% less raw materials than the industry average, reducing cost of sales without compromising performance.
Custom standardization and blending solutions (e.g., synergistic wound healing) with full COA, HPLC, and stability testing.
