Explore our premium industrial-grade raw materials sourced, processed, and quality-tested in our state-of-the-art China manufacturing facilities.
Nigella Sativa, widely recognized as Black Seed or Black Cumin, yields one of the most therapeutically active botanical lipids in the global nutraceutical and cosmetic markets. The pharmacological potency of Nigella Sativa Seed Oil relies directly on its volatile chemical profile, dominantly featuring Thymoquinone (TQ), p-Cymene, and Carvacrol. Standard cold-pressing procedures frequently fall short in maintaining active TQ percentages, leading to volatile active loss.
As a leading global B2B manufacturer, we implement strict, temperature-controlled screw extraction under nitrogen blanket conditions to prevent raw oil oxidation. Our industrial clients leverage this active-stabilized raw material to formulate high-performance skin-barrier moisturizers, metabolic support supplements, and advanced veterinary therapeutics.
By optimizing agricultural cultivation parameters and standardizing factory extraction pathways, we guarantee a consistent supply chain from farm gate to formulation tank, meeting strict microbial, heavy metal, and pesticide threshold tolerances required by global cosmetic and pharmaceutical brands.
Enhancing Bioavailability, Standardization, and Stability of Phytochemical Lipids through Next-Generation Technology
While mechanical cold-pressing retains the natural lipid structure, sub-critical liquid extraction isolates ultra-high concentration Thymoquinone (TQ) variants up to 5% without chemical solvents, preserving volatile terpenes and maximizing purity for pharmaceutical formulations.
Addressing the strong hydrophobic nature and pungent sensory profile of Black Seed Oil, we are developing microencapsulated powders and self-emulsifying drug delivery systems (SEDDS) to double gut absorption kinetics and extend stability in functional foods.
By monitoring growing conditions and using real-time High-Performance Liquid Chromatography (HPLC) testing, our factories adjust extraction settings to achieve uniform fatty acid distributions—specifically focusing on Linoleic Acid (C18:2) and Oleic Acid (C18:1).
For more than 20 years, Nanjing Tong Rui Bio-Tech Co., Ltd. (TRB) has been a leading manufacturer and exporter of botanical extracts and active plant lipids in China. Our integrated model combines agricultural research, extraction technology, and international distribution.
We supply raw materials across multiple categories, including Herbal extracts, Sweeteners, Nootropics, Vegetable & Fruit Juice powders, Essential oils, and Bee Products. Reflecting our commitment to the biological sciences, we were recognized with the 2026 Global Biotechnology and Life Sciences Award as the "Best Global Herbal Extract Provider 2026".
TRB operates three modern manufacturing facilities: one for botanical extracts, one for bee products, and a specialized facility for animal-derived products. These plants run under strict regulatory standards and hold complete GMP, ISO, HACCP, ORGANIC, FDA, HALAL, and KOSHER Certifications.
Lately, TRB has focused on developing innovative Nootropic products, including Brain Health, Anti-Aging, and Longevity ingredients, which have received strong positive feedback from clients in Europe, North America, and Asia.
Customizing Nigella Sativa Seed Oil specifications to meet diverse regulatory and formulating requirements across sectors.
Providing cold-pressed oils with standardized Thymoquinone levels (1% to 3%), dry-blended carriers, and high oxidation stability values (OSI) for long-lasting supplement shelf lives.
Deodorized and color-refined fractions of Nigella Sativa oil, ideal for facial serums, acne creams, and scalp treatments where color and aroma must be light and neutral.
High-purity raw oils suitable for topical skin formulations and soft gel capsule processing, meeting strict European Pharmacopoeia (EP) heavy metal standards.
Every industry faces unique formulation challenges, whether related to visual clarity, heat tolerance, or biological activity. We provide specialized post-processing steps, including natural filtration, dewaxing, nitrogen flushing, and custom compounding. By matching the oil's properties to your end-use, we prevent ingredient separation and extend shelf life in final formulations.
Our extraction facilities in China use automated manufacturing techniques to ensure consistent product quality. We monitor every step of the process—from seed sorting and cold-pressing to final filtration and nitrogen-blanket packaging—via unified control systems. This automation ensures batch-to-batch consistency and prevents raw material oxidation.
We manage risks by using dual-channel sourcing for our Nigella Sativa seeds, importing from organic farms in Egypt and Central Asia while also sourcing from domestic cultivation zones. This dual strategy keeps our production active and stable, regardless of changes in international shipping or local yields.
Our factories run energy-efficient systems that lower utility costs while maintaining high production capacities. By optimizing logistics networks near major coastal shipping ports, we provide competitive bulk pricing and reliable transit times to our clients in North America, Europe, and Asia-Pacific.
Operating under strict international quality management standards to ensure safe, traceable, and reliable botanical ingredients.
At TRB, we prioritize transparency and safety at every step. We document the journey of our Nigella Sativa seeds from the planting site to our final warehouse. Each shipped batch is accompanied by a Certificate of Analysis (COA), which lists our gas chromatography-mass spectrometry (GC-MS) fatty acid profiling and High-Performance Liquid Chromatography (HPLC) active assays.
Our manufacturing and processing facilities are fully certified, meeting the safety and quality standards required for global distribution:
Our Quality Control labs check each batch for heavy metals (such as Lead, Arsenic, Cadmium, and Mercury), polycyclic aromatic hydrocarbons (PAHs), and pesticide residues. By maintaining these strict control steps, we help our clients avoid customs clearance delays and meet the safety guidelines of regulatory bodies like the US FDA and EFSA.

Our standard cold-pressed Black Seed Oil contains natural Thymoquinone levels between 0.5% and 1.5%. For specialized B2B formulations, we offer standardized batches with up to 3% or 5% TQ via controlled extraction and concentration processes.
We use nitrogen-blanketed extraction, storage, and bottling systems. Sparging with nitrogen gas displaces oxygen from containers, protecting the volatile components and keeping the peroxide value (PV) low throughout the oil's shelf life.
We hold GMP, ISO 9001/22000, HACCP, Halal, Kosher, and Organic (USDA/EU) certifications. These standards support smooth import and customs clearance processes in international markets.
Our standard Minimum Order Quantity (MOQ) starts at 25kg (for drums). Lead times vary based on stock availability, but standard production runs are typically ready to ship from our China facilities within 10 to 15 business days.
Yes. We can blend Nigella Sativa oil with other carrier lipids (such as MCT or Linseed oil) or formulate it alongside essential oils to meet your exact specification and aroma requirements.
