Explore our core selection of scientifically standardized natural ingredients
As the primary botanical precursor for commercial Trans-Resveratrol, Giant Knotweed Extract (derived from Polygonum cuspidatum) occupies an indispensable position in the global anti-aging, pharmaceutical, and nutritional sectors. Global supply chains face critical bottlenecks: maintaining high purity without environmental compromise, ensuring strict heavy metal levels under international compliance, and resolving solubility restrictions in functional drinks.
Andy Biotech addresses these market pain points at a macro level. Our vertical supply chain begins with sustainably cultivated agricultural partnerships in Shaanxi province, which boasts optimal climatic conditions for active stilbenoid accumulation. By employing green processing methodologies, we produce standardized extracts ranging from 50% to 98% Trans-Resveratrol, with minimized emodin content to eliminate gastrointestinal irritation. Our customized particle size control and water-dispersible formulations enable seamless formulation integration.
By bypassing traditional high-chemical solvent purification routes, Andy Biotech supplies global manufacturers with a clean-label ingredient that matches the strict regulatory requirements of the United States FDA, the European Food Safety Authority (EFSA), and regional agencies worldwide.
Scientific rigor, high-yield technology, and industry-leading quality benchmarks
Our extraction methodologies preserve the trans-isomer configuration, which is highly sensitive to light and oxidation. We utilize inert gas purging and light-protected amber packaging to guarantee a 3-year shelf life under standard storage conditions.
Emodin is a natural anthraquinone present in Polygonum cuspidatum that acts as a powerful laxative. We employ dedicated macro-porous adsorption resins to isolate and eliminate emodin, keeping the final threshold below 0.1%, ensuring safety for sensitive populations.
Strict adherence to European Union Regulation (EC) No 396/2005 and USP Chapter <561> ensures that all heavy metals (arsenic, lead, cadmium, mercury) and potential pesticide residues remain far below safety limits.

Providing functional value and processing compatibility for developers
Resveratrol is globally researched for its capacity to activate SIRT1 longevity genes and mimic caloric restriction. Our high-purity powder is optimized for encapsulation, tableting, and synergistic formulation with NMN (Nicotinamide Mononucleotide) and Coenzyme Q10.
For skincare, Giant Knotweed Extract acts as a powerful intracellular antioxidant, fighting UV-induced lipid peroxidation and inhibiting tyrosinase to diminish hyperpigmentation. We offer micronized grades for optimal dispersion in emulsions.
Through micro-encapsulation and solubility enhancement techniques, we solve the natural hydrophobic limits of Resveratrol, preventing sedimentation in aqueous solutions and enabling clear, stable, and bioavailable health drinks.

Our state-of-the-art extraction facilities employ advanced technologies, including supercritical solvent and water-based methods, to preserve the full spectrum of bioactive compounds without compromising on environmental responsibility.
Quality and safety are non-negotiable. Every batch undergoes rigorous testing in our in-house laboratories, equipped with HPLC, GC-MS, and other advanced analytical instruments. We guarantee compliance with stringent international standards, including ISO, NSF, cGMP, and related certifications. Our commitment to transparency means you receive comprehensive Certificates of Analysis (CoA) for every product, ensuring traceability and peace of mind.
It’s one thing to just meet the regulations when providing ingredients, but when an ingredient supplier exceeds those standards and imposes even higher ones in its products that is a sign of a company who cares. Andy Biotech takes extra steps to ensure that our independent third-party laboratory-tested ingredients you want meet our standards as well as your own.
Our extensive portfolio features a wide range of standardized extract, ratio extract, and custom blends tailored to specific formulations. Whether you need Echinacea for immune support, Turmeric with high curcuminoid content, or innovative botanical blends for skincare, our technical team works closely with you to deliver exactly what your product requires. Andy Biotech provides high quality Ginkgo Biloba Extract, Lycopene Tomato Extract, Lutein Marigold Extract, Aloe Vera Gel Freeze Dried powder Aloe Vera Extract and other natural ingredients to food, health and nutraceutical industries.
Andy was born in a small village close to Hanjiang River in Hanzhong Shaanxi province, China. Thirty years ago, when she was still a little child, she caught a cold, but the medical services were not available unless the family crossed over high mountains to find a hospital. Thus, Andy's grandfather first used Echinacea leaves soaked in water for her treatment, then he dug Echinacea root and shredded into pulp and squeezed the liquid for Andy to drink one spoon every two hours. Andy recovered after this treatment.
As a child, Andy watched his grandfather harness the healing power of plants in his humble garden. His ancient herbal remedies were not just treatments; they were magic. That early wonder blossomed into a profound passion for plant extracts and a deep respect for nature’s wisdom. From that time on, little Andy swore that he would help to spread all herbs all over the world to give benefit to more people.
This personal journey is the heart of Andy Biotech. It’s why Andy Biotech are dedicated to researching and delivering the purest, most effective botanical solutions for modern wellness. Andy’s lifelong vow is to honor that tradition by innovating for a healthier future, empowering lives through the timeless power of plants.
Third-party validated industrial standards, safety documentation, and global certifications
Bridging pure natural phytochemistry with forward-looking clean-label standards
By transitioning from classic methanol/acetone solvents to food-grade ethanol and water multi-stage countercurrent extraction, we reduce our environmental footprint while guaranteeing zero hazardous solvent residue in the end extract.
Cis-resveratrol does not possess the same physiological benefits as Trans-Resveratrol. Our extraction line works under low-heat, oxygen-free conditions to protect the structural integrity of the trans-isomer, maintaining standard levels above 99% of total stilbenes.
We continuously adjust our purity parameters to align with global regulatory bodies, ensuring that heavy metal ceilings, PAHs, and pesticide levels conform to the ever-stricter FDA, EFSA, and Chinese Pharmacopoeia (ChP) amendments.
