Quality Commitment:

Raw resources from GAP approved farming areas in Sichuan and Hubei provinces are strictly pre-screened. Heavy metals, pesticide residues and active ingredient baseline levels are checked by our quality control system before production starts. Each batch is fully tested and samples are preserved for complete traceability.

Customer-Centric Approach:

We know that your formulation requirements can vary greatly depending on application and market laws. That is why we give free samples and have competitive pricing structures for long-term collaborations. Our logistics network allows us to deliver your products on time by FedEx, DHL, air freight or sea shipment depending on your location and urgency.

Raw Material Selection and Pre-treatment

Manual selection of authentic thick bark from mature Magnolia officinalis trees is used for the removal of branches, leaves and damaged material. Selected bark is washed, sliced, dried at a low temperature and pulverised. Pre-inspection grading avoids poor raw material entering production processes.

Ethanol Extraction Closed Loop at Low Temperature

Active ingredients are extracted from food grade ethanol-water solutions using closed-loop low temperature reflux systems. The whole process is carried out under light-protected and temperature-controlled conditions, so as to maintain the natural ratios of the components, and to avoid oxidative damage. The most efficient method is multi-stage countercurrent extraction.

Refinement of Filtration and Degreasing

Coarse fibres and particle materials are removed using precision plate-and-frame filtration. Degreasing at low temperatures removes fat-soluble pigments and contaminants and provides initially purified solutions that are less prone to oxidation.

Macroporous Resin Enrichment

Gradient loading procedures with water washing eliminate sugar and ash content. The gradient ethanol elution can accurately enrich total biphenolic chemicals and separate ineffective contaminants and water-soluble colourants, making the refined extracts different from typical crude materials.

Multi-Stage Chromatography and Recrystallization

High-purity standards require further separation by column chromatography and low temperature gradient recrystallization. This improved purification step further minimises the residual single impurities and oxidised colourants to get the premium grade powder with better activity profiles.

Low Temperature Vacuum Concentration

Light protected vacuum systems allow for the controlled temperature removal of the ethanol solvent, preventing heat degradation and oxidative discolouration that would damage the integrity of active chemical structures.

Spray Drying and the Formation of Powders

Low-temperature instantaneous spray drying preserves heat sensitive components and produces homogeneous particle distributions with outstanding flowability characteristics.

Batch Homogenization and Sieve

Materials are passed through precision sieves for fineness standards of 80-200 mesh. In large-scale production runs, three-dimensional blending of several batches provides uniformity of colour, composition, and sensory attributes; variances are therefore reduced.

Light-Proof Packaging and Quality Release

Double layer vacuum aluminium foil bags, moisture resistant fibre drums prevent light-induced oxidation. Batch-specific testing verifies active chemical content, solvent residue limitations, heavy metal compliance, and pesticide residue standards before release to the warehouse. Samples are retained for full traceability.

Available Primary Packaging:

Your Magnolia Bark Extract Powder is packaged in pharmaceutical quality double layer aluminium foil bags with nitrogen flushing to minimise oxidation during storage and shipping. Standard quantities include 1kg, 5kg and 25kg configurations, with custom packaging sizes available to meet specific manufacturing needs.

Secondary Protection:

International shipment is protected with the added moisture and impact protection of sealed fibre drums. Each barrel is labelled with batch identification, manufacture dates and specification details for inventory control.

Documentation Package:

Complete shipment documentation: Certificate of Analysis (CoA), third party test results, phytosanitary certifications (where needed), customs declaration materials. Digital copies will be sent to you via email prior to shipping for regulatory review.

Logistics Network:

· Express Shipping: FedEx and DHL services deliver 1-10kg quantities within 5-7 business days to most international destinations

· Air Freight: Consolidated air cargo handles 50-500kg shipments with 7-10 day transit times

· Sea Freight: Container shipping provides cost-effective solutions for bulk orders exceeding 500kg, with transit times varying by destination port

Temperature Control:

Shipments requiring cold chain management receive insulated packaging with temperature data loggers to verify storage conditions throughout transit.

Q: How do you prevent oxidation and discoloration in maritime freight?

A: The finished powder is packaged in double-layer light-proof vacuum nitrogen-filled aluminium foil bags within sealed fibre drums. We can supply accelerated stability test reports that verify the shelf-life performance under light and elevated temperature circumstances.

Q: Are you able to stabilise the raw material pricing on annual framework orders?

A: We sign long-term purchase agreements with the bases of origin and we keep a strategic inventory of raw materials during the harvest seasons. Customers with long-term cooperation can obtain contracts with a fixed price every quarter, which guarantees the stability of costs and priority delivery without stockouts.

Q: How can you make a real bark, no branches, leaves or substitutes?

A: In production, we only use the official medical thick bark of Magnolia officinalis. No branches, leaves or imitation kinds are permitted to enter the processing facilities. Factory audits are accessible with full origin certification and botanical identification papers.
