Magnolia Bark · Purified Actives & High-Purity Extract
Honokiol & Magnolol / Magnolia
Magnolia bark-derived honokiol and magnolol ingredients for formulation, product development, and commercial manufacturing.
Quality Botanical Imports supplies three distinct Magnolia officinalis bark ingredients: Honokiol Isolate, Magnolol Isolate, and a High-Purity Honokiol & Magnolol Extract.
The isolates provide purified single-compound formats, while the combined extract retains both principal active constituents in one high-purity magnolia bark ingredient.
Defined Magnolia Ingredients
More Specific Than “Magnolia Bark Extract”
Magnolia bark can contain both honokiol and magnolol, but the phrase “magnolia extract” alone does not define the concentration or relative profile of either compound.
QBI separates the portfolio into distinct commercial formats so formulators can select a purified single-compound active or a high-purity extract containing both principal constituents.
Exact analytical results are batch-specific and are reported in the documentation applicable to the material being offered.
Available Products
Three Magnolia Bark Ingredient Formats
Each product uses the same botanical source and plant part, but differs in active-compound profile.
Honokiol Isolate
High-purity honokiol supplied as a purified single-compound botanical active.
Magnolol Isolate
High-purity magnolol supplied as a purified single-compound botanical active.
High-Purity Honokiol & Magnolol Extract
High-purity magnolia bark extract containing both honokiol and magnolol as principal active constituents.
Selecting a Format
Isolate or High-Purity Combined Extract?
The naming reflects the actual composition of the ingredient, not simply a purity claim.
Honokiol or Magnolol Isolate
Use an isolate when the formulation requires a high-purity ingredient centered on one defined single compound.
Exact assay is reported in the applicable batch-specific analytical documentation.
High-Purity Honokiol & Magnolol Extract
The combined material intentionally contains both honokiol and magnolol and is therefore described as a high-purity extract rather than an isolate.
The applicable lot documentation identifies the measured constituent profile of the material being supplied.
Qualification Process
How QBI Qualifies Magnolia Actives
Supplier Qualification
QBI evaluates production capability, documentation quality, technical responsiveness, commercial reliability, and representative material before scale-up.
Analytical Evaluation
Supplier specifications and certificates of analysis are reviewed alongside independent potency testing where appropriate for honokiol, magnolol, or both constituents.
Commercial Lot Review
Commercial material is reviewed with documentation applicable to the specific lot being offered or supplied.
Analytical Documentation
Potency Testing and Full-Panel Testing
Active-compound assay and contaminant testing answer different questions.
QBI's Magnolia documentation includes analytical information applicable to honokiol, magnolol, or the combined constituent profile of the material being supplied.
Full contaminant testing is not represented as automatically applying to every QBI inventory lot.
When a current full-panel result is available for the offered lot, it can be provided with the applicable documentation. For commercial orders of 1kg or more, additional full-panel testing can also be arranged when required, with laboratory testing charged at pass-through cost.
Testing scope and lead time should be established before a commercial order is finalized when specific requirements are important to the application.
Additional Testing May Include
- Heavy metals
- Pesticides
- Residual solvents
- Microbial testing
- Additional constituent analysis where appropriate
- Other analyses relevant to the material or intended application
Lot Documentation
Batch-Specific Documentation
Documentation available for Magnolia ingredients may include:
- Batch-specific certificate of analysis
- Independent honokiol and/or magnolol assay
- Available contaminant-screening results
- Botanical source information
- Safety data sheet
- Storage and handling information
- Country-of-origin information
- Packaging and availability information
The documentation package may vary by product, production lot, order quantity, testing status, and customer requirements.
