What Is a Standardized Extract?

Standardized Extracts are botanical ingredients produced to meet a defined specification for one or more active or marker compounds. Standardization helps buyers compare materials using measurable criteria rather than relying only on the plant name or a general extract description.

Specifications and Product Differences

Products in this category may differ in botanical source, plant part, extraction method, extract ratio, active-content level, analytical method, carrier content, solubility, and physical form. A declared extract ratio alone does not necessarily mean that a product is standardized; the stated marker or active-content specification should be supported by appropriate product documentation.

Information to Review Before Sourcing

Buyers should review the botanical name, plant part, standardized compound, assay value, test method, carrier information, and available analytical documents. Stability, solubility, processing compatibility, and intended formulation use should also be considered when selecting an ingredient for supplements, functional foods, beverages, or personal care products.

Category Scope

This category is intended for botanical extracts with a defined and verifiable specification. General Herbal Extracts without a declared marker or active-content level should be placed under Herbal Extracts. Purified Pharmaceutical APIs and isolated nutritional compounds should remain in their respective categories.

Standardized Extracts
Pharmaceutical-Grade Standardized Botanical Extracts

High-potency standardized extracts with guaranteed active compound levels verified by HPLC: Curcumin 95%, Green Tea EGCG 50-98%, Resveratrol 50-99%. Pharmaceutical-grade extraction ensures superior quality and batch-to-batch consistency. Each extract includes comprehensive documentation: CoA, heavy metal testing, microbial analysis, and stability data for regulatory compliance and product development.
