Explore our range of premium, standardized plant extracts manufactured under strict GMP compliance.
Standardized extraction metrics targeting high-concentration bioactive compounds for therapeutics, preservation, and cosmetics.
Clove extract, derived from the flower buds of Syzygium aromaticum, is highly valued for its rich concentration of bioactive volatile compounds. As a premier wholesale cloves extract manufacturer, TRB implements advanced separation technologies to yield precise concentrations of eugenol, eugenyl acetate, and beta-caryophyllene.
Our extraction lines utilize raw materials imported from certified origins, ensuring strict geographical traceability. By configuring parameters like pressure, temperature, and solvent ratios, we yield standardized powder and liquid formats tailored specifically to international pharmaceutical, dental, nutraceutical, and cosmetic standards.
| Active Ingredient | Standard Specification | Test Method | Primary Application |
|---|---|---|---|
| Eugenol | 70% - 98% | GC-MS / HPLC | Dental analgesic, antiseptic |
| Eugenyl Acetate | 5% - 15% | HPLC | Flavoring, antioxidant synergy |
| Beta-Caryophyllene | 2% - 12% | GC-MS | Anti-inflammatory, aroma agent |
| Total Phenolics | ≥ 250 mg GAE/g | Folin-Ciocalteu | Natural shelf-life preservation |
A contrast analysis of technologies that define yield efficiency, purity, and thermal integrity of clove extractives.
Utilizes pressurized carbon dioxide at supercritical states as a solvent. This low-temperature process completely avoids thermal degradation of delicate monoterpenes and volatile phenols. It yields a clean solvent-free product, ideal for premium aromatherapy, dental care, and clean-label dietary supplements.
The traditional, scalable method for volatile oil extraction. We employ advanced closed-loop fractionated steam distillation systems to isolate essential oils with optimal eugenol yields. Optimized thermal profiles reduce hydrolysis of eugenyl acetate into eugenol, preserving natural botanical ratios.
Targeted for water-soluble polyphenols, tannins, and flavonoids. Our automated industrial reactors utilize food-grade solvent mixtures to maximize yield, followed by vacuum concentration and spray-drying inside Class 100,000 cleanrooms to produce high-density water-soluble clove powders.
Nanjing Tong Rui Bio-Tech Co., Ltd. (TRB) operates three specialized manufacturing facilities that integrate Industrial IoT (IIoT) platforms for real-time monitoring of pressure, temperature, flow rates, and concentration metrics.
By shifting to an automated closed-loop production system, we prevent raw material contact with external contaminants, achieving absolute purity. Our digital system monitors batches from botanical sourcing through pre-treatment, extraction, micro-filtration, and packaging. This allows global clients to view compliance dashboards and access real-time regulatory files, certificates of analysis, and batch chromatograms.
Additionally, our continuous raw material sourcing agreements across primary growth zones globally buffer our production schedules against environmental disruptions, ensuring uninterrupted wholesale supply throughout the calendar year.
How global product developers deploy cloves extract across multi-sector commercial applications.
Eugenol's inherent local anesthetic and antibacterial properties make it a staple ingredient in dental pastes, temporary fillings, and antiseptic mouthwashes targeting oral pathogens.
Acts as an effective natural alternative to synthetic preservatives. Inhibit lipid oxidation and antimicrobial growth in meat, seafood, and oil emulsions, extending commercial shelf-life.
Applied in formulations to soothe localized irritation and fight acne-causing bacteria. Its high antioxidant capacity helps neutralize free radicals, protecting skin from aging.
Used as an antibiotic alternative in animal feeds. Clove extractives optimize intestinal microbial flora, enhancing digestive absorption and overall growth efficiency in livestock.
Meeting strict international regulatory standards to guarantee supply-chain safety and seamless customs clearance.
TRB's manufacturing operations carry complete certifications including GMP, ISO, HACCP, ORGANIC, FDA registration, HALAL, and KOSHER. These verify that our output meets regional food, feed, and drug standards globally.
Every batch undergoes ICP-MS screening for heavy metals, GC-MS/HPLC analysis for active marker compliance, and gas chromatography tests for residual solvent and pesticide levels.
We provide complete regulatory documentation including MSDS, COA, Allergen Statements, GMO declarations, and phytosanitary certificates, ensuring rapid clearance at US, EU, and Asian ports.
Pioneering tomorrow's phytochemistry through bio-efficiency, targeted delivery, and synergistic botanical formulations.
One of the limitations of volatile compounds like eugenol is their susceptibility to thermal degradation and rapid oxidation. TRB is engineering high-efficiency polymeric matrix microencapsulation for clove extract essential oils. By coating eugenol at the molecular level with cyclodextrins or liposomal shells, we achieve sustained release profiles and long-term shelf stability in aqueous environments.
🌱Consistent with our corporate focus on anti-aging and brain health, our R&D team is exploring synergistic formulations that combine clove extract with other bioactive compounds. For instance, pairing the neuroprotective potential of clove beta-caryophyllene with nootropic herbs is a key area of study, showing promise in optimizing cellular response and systemic resilience.
Our roadmap emphasizes reducing our ecological footprint. We are transitioning our manufacturing plants toward zero-effluent water cycles, solar thermal heat integration for steam generation, and bio-enzyme pre-treatments that soften botanical cell walls to lower electricity and extraction runtimes. By choosing TRB, global buyers support a sustainable procurement program aligned with international environmental initiatives.
Providing technical and logistical answers for procurement managers, formulation scientists, and quality auditors.
We supply Cloves Extract in various specifications. Our powdered extracts are standardized from 10:1 ratios to 70% eugenol, while our liquid essential oil extracts range from 85% to 98% pure eugenol by GC-MS analysis, depending on your target formulation needs.
We use only water and ethanol as extraction solvents in our physical processing plants. Supercritical carbon dioxide extraction uses gaseous CO2 under pressure, leaving no residues whatsoever. Analytical checks for residual solvents are executed per USP <467> guidelines.
Our standardized powders have a stable shelf life of 24 months when stored in sealed, airtight drums in a cool, dry area away from direct light. We use aluminum foil bags for intermediate packaging to protect the product from light and humidity.
Every batch of raw clove buds is screened for pesticide residues prior to extraction. We test for over 200 organochlorine, organophosphorus, and pyrethroid pesticide residues using GC-MS/MS, ensuring full compliance with both FDA tolerances and European Pharmacopoeia limits.
Yes. Our clove extracts are 100% plant-derived from Syzygium aromaticum without genetic modifications. We utilize no animal-derived processing aids or carriers, making our products fully suitable for vegan and vegetarian brands.
Certainly. We offer customized milling services, adjusting particle distributions from 80 mesh to 120 mesh to fit your tableting, hard gelatin capsule filling, or instant water-dissolving mix specifications.
