Analytical Standards for Specialty Botanical Extracts
Batch-specific identity, potency, and contaminant testing for standardized botanical ingredients
In specialty botanical sourcing, supplier-provided paperwork is only the starting point. QBI uses a two-part verification process before releasing imported materials for wholesale distribution: identity and potency review through qualified analytical partners, followed by contaminant screening appropriate to the ingredient and intended commercial use.
Our goal is to help formulators reduce sourcing risk, compare lots more confidently, and evaluate ingredients using batch-specific documentation rather than unverifiable claims.Every batch of botanical material we import is sequestered and reviewed before release for wholesale distribution. This review may include supplier documentation, identity and potency testing, and contaminant screening through qualified U.S.-based analytical partners, depending on the ingredient, specification, and intended commercial use.
For a practical buyer checklist, see QBI’s guide to verifying standardized botanical extracts. For a product-level example, see how QBI applies this specification-driven testing and release process to its verified 98% nuciferine isolate.
Identity & Potency Verification
QBI works with qualified analytical partners to evaluate botanical identity and marker-compound content using fit-for-purpose methods such as HPTLC, HPLC, microscopy, or other applicable analytical approaches. This helps buyers compare supplier claims against batch-specific data before committing to larger orders or finished-product development.
Contaminant & Quality Screening
Potency is only one part of ingredient qualification. QBI works with qualified U.S.-based laboratories to evaluate contaminant profiles such as heavy metals, pesticides, residual solvents, and microbial content. Testing panels are selected based on the ingredient, specification, and intended commercial use.
