How should buyers compare botanical extract specifications?

DIRECT ANSWER

Do not compare botanical extracts by price or extract ratio alone. First align botanical species, plant part, extraction solvent, carrier, marker or active content, analytical method and contaminant limits. Products with similar names may represent materially different grades.

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.
