Feature and Advantage
Natural Origin & Clean Label
Our herb extracts are derived from premium-quality plant sources with no artificial colors, additives, or synthetic preservatives. We offer clean-label solutions that meet consumer demand for natural ingredients. Selected products are available in organic-certified grades for premium formulations.
High Purity & Batch-to-Batch Consistency
Every batch is rigorously tested to ensure consistent active compound content. We offer both standardized extract ratios and precisely controlled active ingredient specifications—such as polyphenols, flavonoids, and other marker compounds—to meet diverse formulation requirements for herbal supplements and nutraceuticals.
Excellent Processability
Our extracts feature uniform particle size—100% through 80 mesh—ensuring smooth integration into capsules, tablets, powders, and various delivery systems. Water-soluble options are available for beverages and liquid formulations. Advanced low-temperature extraction and drying technologies preserve the delicate bioactive compounds and full phytocomplex of each plant.
Broad Functional Activity
Our herb extracts deliver multiple functional benefits—antioxidant, anti-inflammatory, antimicrobial, and pharmacological activities—making them suitable for pharmaceuticals, cosmetics, food, and nutraceuticals. Whether you are formulating herbal supplements or developing medicinal herb-based products, our extracts provide reliable performance.
Customizable Specifications, Packaging & Finished Products
We offer flexible content specifications to match your formulation needs. Packaging options include aluminum foil bags, cardboard drums, cartons, and custom packaging upon request. Beyond raw extracts, we provide value-added processing services to produce finished dosage forms such as capsules, softgels, gummies, and tablets—streamlining your supply chain from ingredient to shelf-ready supplements.
Advanced Delivery Technologies
We develop innovative formulations like plant liposome products that protect targeted active ingredients and significantly enhance absorption rates, ensuring maximum bioavailability for your finished supplement products.
Plant Extraction Methods – Industrial Overview
In the botanical extract industry, the extraction method directly determines product purity, active compound content, quality, and cost. As a professional ingredient supplier, we apply different extraction technologies to maximize the value of raw materials for food, supplement, and cosmetic applications.
Globally, plant extraction follows a standard workflow: Pre-treatment → Extraction → Separation → Purification → Drying. The extraction step is the foundation of product quality. Below are the most widely used industrial methods.
1. Solvent Extraction – The Most Versatile Method
- Principle: Uses "like dissolves like" – solvents such as water, ethanol or acetone penetrate plant cells to dissolve and release active compounds.
- Applications: Primary method for standardised extracts (e.g., Goji Berry Polysaccharides, Reishi Mushroom Triterpenes). We select water or ethanol extraction based on the polarity of target compounds using multi-functional extraction tanks.
- Advantages: Mature technology, moderate equipment investment, cost-effective, suitable for large-scale production.
- Limitations: Longer extraction cycles; may require additional purification steps.
2. Distillation & Cold Pressing – For Volatile Aromatic Compounds
- Steam Distillation: Extracts essential oils and volatile oils (e.g., Peppermint Oil, Rose Oil). High-temperature steam carries volatile components, which are then condensed and separated. High equipment investment and precise process control are key technical barriers.
- Cold Pressing (Mechanical Expression): Mainly used for citrus peel oils (e.g., Orange, Lemon). Physical pressure ruptures oil sacs, followed by water spraying and centrifugal separation to obtain fresh oil.
3. Supercritical Fluid Extraction – High-Purity, Residue-Free Technology
- Principle: Uses supercritical CO₂ as a solvent under specific temperature and pressure to precisely dissolve target compounds, then separates them through pressure reduction.
- Commercial Value: Ideal for high-value actives like Curcumin and high-purity Lycopene. Key benefits: zero solvent residue, meets strict organic/purity standards, and low-temperature operation preserves heat-sensitive compounds.
4. Assisted Extraction Technologies – Efficient, Energy-Saving Modern Methods
- Ultrasound-Assisted Extraction: Uses ultrasonic cavitation to disrupt cell walls, accelerating compound release. Significantly reduces extraction time and improves efficiency with lower energy consumption and high automation.
- Microwave-Assisted Extraction: Uses microwave energy for selective heating, building internal pressure to rupture cells and release compounds quickly. Enables shorter production cycles and higher efficiency.

|---|---|---|
| Solvent Extraction | Standardised extracts, bulk production | Cost-effective, versatile |
| Steam Distillation | Essential oils, volatile aromatics | High equipment investment |
| Cold Pressing | Citrus oils, heat-sensitive oils | Maintains fresh aroma |
| Supercritical Fluid | High-purity, residue-free products | Premium quality, higher cost |

Production Process
Our herb extract manufacturing process follows strict quality control at every stage
Raw Material Selection: Sourcing premium medicinal herbs and plant materials from certified suppliers
Cleaning & Crushing: Thorough cleaning and size reduction of raw herbs
Extraction: Advanced extraction using ethanol/water, percolation, or specialized methods to produce concentrated extracts
Concentration: Vacuum evaporation or distillation to concentrate the extract
Spray Drying: Converting liquid extract into fine powder
Sieving & Milling: Particle size standardization (100% through 80 mesh)
Quality Inspection: Testing for active compound content, heavy metals, and microbiology
Packaging: Sealed packaging in aluminum foil bags or paper drums
Warehousing & Shipping: Proper storage and global distribution
Product Quality Control
Quality control is the backbone of botanical extract manufacturing, ensuring that every batch meets the required safety, purity, and potency standards for global distribution. Our quality assurance system spans the entire production cycle – from raw material sourcing to final release.
We begin with strict supplier audits and incoming inspection of all botanical raw materials. Each batch is verified for botanical identity (macro- and microscopic examination), heavy metals, pesticide residues, and microbial contamination before entering production.
Throughout the extraction, concentration, and drying stages, we conduct real-time monitoring of critical process parameters such as temperature, pressure, pH, and extraction time. This ensures batch-to-batch consistency and prevents deviations before they occur.
Finished products undergo comprehensive testing using HPLC, UV-Vis, and GC to confirm active ingredient content, alongside physical property analysis (particle size, bulk density, moisture content) and contaminant screening. Only batches meeting all specifications are released with a full Certificate of Analysis (COA).
Our quality system is aligned with GMP standards and complies with international food safety and cosmetic ingredient regulations, supporting smooth customs clearance and market access for our clients.
