Consistent quality, reliable supply, and a partner who understands your formulation needs. We are Fufeng Snotra Bio-Tech Co., Ltd. – 18 years in botanical extraction, from our own cultivation bases to our GMP-compliant manufacturing facilities. Our Natural Plant Extract portfolio includes Welsh Onion Leaf Extract (Allium fistulosum L.), also known as Green Onion Leaf Extract, Scallion Leaf Extract, Fistular Onion Stalk Extract, 青葱提取物, or葱叶提取物. Derived from the dried green leaves of the onion plant — with over 2,000 years of cultivation history in China and widely distributed across the country — this extract delivers a rich profile of natural bioactive compounds including allicin, flavonoids, sulfur compounds, and phenolic acids. It is widely used in dietary supplements, functional beverages, food products, and cosmetic formulations for its antioxidant, anti-inflammatory, immune-modulating, and detoxification properties. We offer ratios from 5:1 to 200:1, custom granulation, and private-label packaging – exactly what your formulation requires.

Background: A North American nutraceutical brand was developing a natural immune support and detoxification supplement line. They wanted a plant-based ingredient with clinically-recognized antimicrobial and antioxidant properties to differentiate their products in the competitive wellness market.
Challenge: Their previous supplier could not provide consistent batch quality – allicin and flavonoid content varied significantly between lots, and the powder had poor solubility in their beverage applications.
Solution: We supplied Welsh Onion Leaf Extract standardized to 10:1 with full COA documentation including TLC/HPLC/UV assay, moisture, particle size (80 mesh), heavy metals, and microbiology. We provided custom 80-mesh granulation for better dispersion in their mixing equipment and private-label packaging in 5 kg and 25 kg sizes.
Result: The brand successfully launched their immune support supplement across 15+ North American retail channels. Batch consistency has been maintained at ±3% variance across 20+ production lots. Their procurement lead time reduced by 25%, and they have since added a functional beverage SKU featuring our Welsh Onion Leaf Extract.
Welsh Onion Leaf Extract (Allium fistulosum L.) is derived from the green leaves of the plant and is rich in allicin, flavonoids, and sulfur compounds with antioxidant and anti-inflammatory properties. Onion Bulb Extract (Allium cepa L.) is derived from the underground bulb (onion head) and is commonly used for its quercetin and cardiovascular support properties. While both come from the Allium genus, they have distinct chemical profiles and applications.
Our facility holds ISO9001, ISO22000, HACCP, HALAL, and Kosher certifications – these are factory-level quality management systems. For each batch of Welsh Onion Leaf Extract, we provide a Certificate of Analysis (COA) covering botanical identification (TLC), allicin/flavonoid assay (HPLC/UV), moisture, particle size (80 mesh), heavy metals, and microbiology. Our products are produced using advanced spray drying technology with no artificial additives, colors, or preservatives. If you need product-specific third-party certifications (organic) or additional tests, please contact us – we can arrange these based on your order volume and target market requirements.
Typical starting points based on industry practice:
• Dietary supplements (capsules/tablets): formulate to deliver target allicin/flavonoid content
• Solid beverages / drink mixes: 5%
• Liquid beverages: 5%
• Functional foods / snack foods: 3-5%
• Skincare / cosmetic formulations: 1%-5%
• Animal feed / veterinary products: 0.5%-2% of feed formulation
We recommend working with your R&D team to determine optimal levels for your specific formulation and target market. We provide formulation guidance and technical support upon request.
