Standardized Extracts

Find botanical extracts with named markers or listed content specifications. Select by the compound or group your formulation requires, then review the extraction ratio, assay method and plant-part information separately.

Before you shortlist

Compare the analyte, then the percentage

A percentage is useful only when it identifies the measured constituent, analytical method and reporting basis. Product-family pages keep listed grades together.

  1. 01

    Named constituent

    Name the compound or group you need measured; do not infer it from a high-strength claim.

  2. 02

    Assay and reporting basis

    Confirm whether the result is as-supplied or on a dry basis, and how a total is defined.

  3. 03

    Grade-specific method and documents

    Ask for the matching specification, representative COA and lot relationship.

Source-listed fields help prepare questions. They are not current lot-release results or confirmation that these materials are interchangeable.

Selection and purchasing

Questions before you shortlist

Do two listed percentages necessarily measure the same thing?

Compare the named analyte or compound group, analytical method and reporting basis first. An extract ratio, a marker assay and a broad constituent-group result are different definitions, even when each is expressed alongside a percentage.

Do I need a new enquiry for every listed grade?

Use the existing material page to identify the grade or source wording you want to clarify. If several source listings are grouped together, request the current written definition of the offered grade rather than assuming all listed alternatives are available.

Your next step

Prepare a category enquiry

Describe what you know about the material and intended use. You can ask for help with an unresolved specification; a confirmed MOQ, sample offer or delivery date is not assumed.
