Corydalis-Derived Active · Commercial Supply
Tetrahydropalmatine (THP) / Corydalis
High-purity tetrahydropalmatine for formulation, product development, and commercial manufacturing.
Quality Botanical Imports supplies THP Isolate as a defined single-compound botanical active derived from Corydalis yanhusuo.
Material is evaluated with batch-specific analytical documentation to give formulators and sourcing teams greater visibility into the ingredient being supplied.
Defined Botanical Active
A Defined Active, Not Just a Corydalis Extract
A generic Corydalis extract does not define how much tetrahydropalmatine is present.
Botanical extracts can vary according to species, plant material, manufacturing process, and production lot. For formulators who need substantially greater control over THP content, an isolate provides a more defined single-compound ingredient format.
QBI supplies tetrahydropalmatine as THP Isolate rather than incorporating a fixed assay percentage into the product name. Exact analytical results are batch-specific and are reported in the applicable documentation.
Development Through Commercial Scale
THP Isolate Supply for Formulators
QBI supports evaluation, product-development, and commercial sourcing requirements for THP Isolate.
Evaluation & R&D
Request specifications, available analytical documentation, and sample options for formulation screening and product-development work.
Commercial Supply
Contact QBI for current inventory, kilogram-scale availability, lead time, commercial pricing, and ongoing supply requirements.
Testing Requirements
Buyers with specific potency, contaminant, or documentation requirements can establish the required testing scope before the commercial order is finalized.
Qualification Process
How QBI Qualifies THP Isolate
Supplier Qualification
QBI evaluates manufacturing partners based on production capability, documentation quality, technical responsiveness, commercial reliability, and their ability to support representative material for evaluation.
Analytical Evaluation
Supplier specifications and certificates of analysis are reviewed alongside independent analytical testing where appropriate when qualifying material.
Commercial Lot Review
Commercial material is reviewed with documentation applicable to the lot being offered or supplied. Exact THP assay may vary between qualified production lots.
Analytical Documentation
Potency Testing and Full-Panel Testing
Potency verification and contaminant testing answer different questions.
QBI's THP Isolate documentation includes analytical information applicable to the tetrahydropalmatine content 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 requirements are important to the application.
Additional Testing May Include
- Heavy metals
- Pesticides
- Residual solvents
- Microbial testing
- Other analyses appropriate to the material or intended application
Lot Documentation
Batch-Specific Documentation

Frequently Asked Questions
THP Isolate FAQ
What does “THP Isolate” mean?
QBI uses “isolate” to describe a high-purity, single-compound botanical ingredient rather than a standardized multi-component Corydalis extract.
The exact tetrahydropalmatine assay is batch-specific and is reported in the applicable analytical documentation.
Is every batch the exact same potency?
No. Analytical results may vary between production lots. QBI therefore identifies the material as THP Isolate and provides the applicable batch-specific analytical result rather than incorporating a fixed percentage into the product name.
Does every lot receive full-panel contaminant testing?
Not necessarily. Available full-panel testing is provided when applicable to the offered lot. For commercial orders of 1kg or more, additional full-panel testing can be arranged when required and charged at pass-through laboratory cost.
Can I request a THP Isolate sample?
Yes. Submit a sample and documentation request with your intended application and estimated commercial quantity. QBI can confirm current sample availability and applicable documentation.
Is kilogram-scale THP Isolate available?
Commercial buyers can contact QBI for current inventory, kilogram-scale availability, lead time, documentation requirements, and commercial pricing.
