Magnolia Bark · High-Purity Combined Extract

High-Purity Honokiol & Magnolol Extract

A high-purity Magnolia officinalis bark extract containing both honokiol and magnolol as principal active constituents.

Quality Botanical Imports supplies this material for formulation, product development, and commercial manufacturing where a concentrated combined Magnolia active profile is preferred over a single-compound isolate.

Honokiol and magnolol results are batch-specific and are reported in the analytical documentation applicable to the material being offered or supplied.

Two Defined Magnolia Actives

Why We Call This an Extract, Not an Isolate

An isolate is centered on one purified compound. This material intentionally contains two.

Honokiol and magnolol are distinct naturally occurring constituents of Magnolia bark. Because both compounds are intentionally retained as principal actives in this ingredient, QBI describes the product as a High-Purity Honokiol & Magnolol Extract.

This distinguishes it from Honokiol Isolate and Magnolol Isolate while still communicating that the ingredient is substantially more concentrated and defined than a generic Magnolia bark extract.

Exact constituent concentrations and the relative honokiol-to-magnolol profile are determined by the applicable production lot and analytical documentation.

Defined Combined Profile

A More Specific Magnolia Bark Ingredient

“Magnolia bark extract” alone does not establish the concentration or relative profile of honokiol and magnolol.

Honokiol

Honokiol is independently measurable and is reported as a distinct constituent rather than being treated interchangeably with magnolol.

Magnolol

Magnolol is a separate Magnolia bark constituent with its own analytical result and should be evaluated independently when reviewing the ingredient profile.

Combined Extract Profile

The applicable batch documentation identifies the measured constituent profile of the offered material rather than relying solely on a generic extract ratio.

Selecting a Magnolia Format

Combined Extract or Single-Compound Isolate?

QBI offers both approaches so formulators can select the ingredient architecture that fits the project.

Combined Extract

High-Purity Honokiol & Magnolol Extract

Choose the combined extract when the formulation calls for a concentrated Magnolia-derived ingredient retaining both honokiol and magnolol.

Exact constituent concentrations and relative profile are reported for the applicable lot.

Isolates

Honokiol Isolate or Magnolol Isolate

Choose an isolate when the formulation requires one purified compound as the primary defined active.

QBI supplies both Honokiol Isolate and Magnolol Isolate as separate single-compound ingredient formats.

Qualification Process

How QBI Qualifies the Combined Extract

1

Supplier Qualification

QBI evaluates production capability, documentation quality, technical responsiveness, commercial reliability, and representative material before scale-up.

2

Constituent Evaluation

Supplier specifications and certificates of analysis are reviewed alongside independent honokiol and magnolol testing where appropriate when qualifying material.

3

Commercial Lot Review

Commercial material is reviewed with documentation applicable to the lot being offered or supplied. Constituent results may vary between qualified lots.

Analytical Documentation

Constituent Testing and Full-Panel Testing

Honokiol and magnolol assays answer a different question from contaminant testing.

QBI's combined Magnolia extract documentation includes analytical information applicable to the honokiol and magnolol 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 the commercial order is finalized when specific testing 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 intended application

Lot Documentation

Batch-Specific Documentation

Documentation available for the High-Purity Honokiol & Magnolol Extract may include:
