Align identity and composition
Confirm the scientific name, plant part, extraction process, native extract or carrier basis, and whether the specification is standardized to a defined constituent. An extract ratio does not automatically state the concentration of an active compound.
Compare methods and risk controls
An assay result is meaningful only with a suitable method and calculation basis. Review identity testing, moisture, residual solvents, pesticides, heavy metals and microbiology according to the material and target market.
