Plant Extraction Methods
Extraction determines purity, active content, and cost, so we match the technology to each raw material and target compound rather than running everything through one process. All production follows the same route — pre-treatment → extraction → separation → purification → drying — and the extraction step sets the ceiling on final quality.
| Method | How it works | Best for | Keep in mind |
|---|---|---|---|
| Solvent extraction (water / ethanol) | Solvent dissolves target compounds from prepared plant material | Standardized extracts, bulk production | Most versatile and cost-effective; longer cycle |
| Steam distillation | Steam carries volatile compounds, condensation separates them | Essential oils, volatile aromatics | Higher equipment investment |
| Cold pressing | Physical pressure ruptures oil sacs, centrifugal separation recovers the oil | Citrus oils, heat-sensitive oils | Preserves fresh aroma |
| Supercritical CO₂ | CO₂ under controlled pressure dissolves target compounds, released by pressure reduction | High-value actives (curcumin, high-purity lycopene) | Zero solvent residue; premium cost |
| Ultrasound-assisted | Cavitation disrupts cell walls to release compounds faster | Faster, lower-energy extraction | Shorter cycle |
| Microwave-assisted | Selective heating builds internal pressure to rupture cells | Rapid extraction, high yields | Fast processing |
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.

FAQs
Q: What is the difference between a standardized extract and a ratio extract?
A: A standardized extract is adjusted so that one or more named marker compounds meet a guaranteed content — for example 95% curcumin or 98% EGCG — and the result is verified batch by batch. A ratio extract (such as 10:1) states how much dried raw herb goes into one part of finished powder, so the marker content follows the harvest. Choose a standardized grade when your formula depends on a fixed active dose, and a ratio extract when you want a broader botanical profile.
Q: Can you customize the active content or the specification?
A: Yes. We produce grades from a few percent up to 98% purity and can adjust the marker content, particle size and solubility to match your target formula. Send us the specification you need and we will confirm feasibility and lead time before you commit — or provide a sample first so you can validate it in your own application.
Q: Are the extracts water-soluble, and what particle size do you supply?
A: Standard powders pass 100% through 80 mesh. Water-soluble grades are available for beverages, liquid formulas and ready-to-drink applications, while oil-soluble and liquid aromatic ingredients cover other systems. Tell us the target system when you enquire and we will recommend the grade that disperses correctly in it.
Q: Can you supply a custom blend of two or more extracts?
A: Yes. We blend extracts into a single premix to your ratio and pack it under your own specification, so you receive one COA covering the combined actives instead of several incoming materials to qualify.
Q: Can you supply certified organic, Kosher or Halal grades?
A: Organic (USDA / EU) certification is available on selected products and depends on raw material availability for that harvest; Kosher and Halal certification are available as options. Tell us which certificate you need and we will confirm availability for the specific item before you order.
