Preamble (Rationale for Enactment)
The composition of saw palmetto raw materials varies not only with botanical identity but also with the parts used, collection location, state of drying and extraction method. In particular, for lipid extracts derived from fruit, fatty acid and sterol composition, control of extraction solvents, and differentiation from other oils are central to quality verification. The weight of powdered fruit is also distinct from the amount of marker constituents in an extract. This Standard is established to clarify botanical identification, extract composition, content units, and verification of oxidation and admixture.
Article 1 (Purpose)
The purpose of this Standard is to assess the identity of the botanical species and parts used, collection and processing origins, extract forms, labeling of fatty acids and other constituents, stability, authenticity testing, contaminant testing and cautionary information for health foods using saw palmetto.
Article 2 (Scope)
This Standard applies to the fruit of Serenoa repens, its powder, lipid extracts and other processed raw materials derived from the fruit, and to oral products incorporating them. Other plants in the palm family, other plant parts or oils from other species shall not be treated as saw palmetto fruit raw materials, and the individual constituents of blended raw materials shall be distinguished.
Article 3 (Terms and Definitions)
- 1. Botanical identity: The state of being identified as the fruit of Serenoa repens by scientific name, part used and botanical characteristics.
- 2. Fruit powder: A raw material obtained by drying and grinding fruit without selective concentration by extraction.
- 3. Lipid extract: A raw material consisting principally of the fat-soluble fraction obtained from fruit using a solvent or another method.
- 4. Fatty acid composition: Analytical information showing the proportions of individual fatty acids constituting an extract, including their free or bound states.
- 5. Authenticity assessment: Examination using botanical documentation, chemical fingerprints and composition to identify discrepancies associated with other plant species or extraneous oils.
Article 4 (Requirements)
- 1. For the source plant, the scientific name, part used, collection or cultivation region, post-harvest treatment and supply lot shall be recorded, and receipt specifications shall be established to prevent unintended admixture of parts other than fruit. In addition to botanical verification by appearance, microscopy or similar means, the applicability of appropriate chemical fingerprints or genetic methods shall be evaluated at stages where grinding or extraction makes morphological identification difficult. Information on the origin of reference specimens or reference documentation shall be retained.
- 2. Fruit powder, simply pressed oil and lipid extracts shall be distinguished. For extracts, the extraction solvent, extraction ratio or relationship between raw material and extract, and an outline of refining and solvent removal shall be stated in the specification. Where an equivalent amount of powdered fruit is labeled, the conversion basis shall be recorded. Extract weight or the amount of fruit added shall not be treated as the amount of fatty acids. Origin and processing classification shall be verified using supplier process flow diagrams.
- 3. For lipid extracts, items enabling assessment of authenticity and consistency between lots shall be selected, including total fatty acids, the treatment of free and bound fatty acids, the composition of principal fatty acids, and sterols. The business operator shall establish specification limits on the basis of documentation on authentic raw materials, manufacturing methods and analytical variability, and shall make the limits and their supporting rationale publicly available or available upon inquiry. A single marker shall not serve as a substitute for botanical identity.
- 4. Content labeling shall clearly distinguish the amount of fruit powder from the amount of extract per recommended daily intake. Where fatty acid content is stated, mass units and the analytes quantified shall also be given. The amounts of total fatty acids, free fatty acids, individual fatty acids and sterols shall not be used interchangeably, and values calculated from raw material specifications shall be distinguished from values measured in the finished product. Oily excipients shall not be included in the amount of extract-derived lipids.
- 5. Authenticity assessment shall verify fatty acid profiles, sterol composition and other chemical fingerprints across multiple lots and examine signs of oil admixture inconsistent with the botanical species or manufacturing method. Where other edible oils are intentionally incorporated into a finished product, oils used in the formulation and saw palmetto extract shall be recorded separately, and this distinction shall be reflected in the interpretation of analytical results. Comparative documentation shall be prepared whenever the supplier is changed.
- 6. For stability evaluation and testing, items shall be selected from lipid oxidation status, moisture, microorganisms, pesticide residues, heavy metals and extraction solvents according to whether the material is a powder or extract and the processes used. Oxidation indicators shall be linked to the light protection provided by packaging, oxygen contact and conditions after opening, and the business operator shall establish assessment specifications. When external test results are disclosed, it shall be made clear whether the sample was the botanical raw material, extract or finished product.
- 7. Labeling shall consistently state the scientific or common name, use of fruit, whether the material is a powder or extract, the substance or material to which the stated content refers, and storage instructions. Statements concerning extraction solvents shall correspond to the actual manufacturing process and residual solvent testing. Allergens originating from botanical raw materials or formulation bases shall be evaluated, and guidance on consultation based on the latest information from public authorities shall be provided for persons who are pregnant or breastfeeding, taking medicinal products or under medical supervision. Instructions to discontinue use in the event of abnormalities and contact details shall also be provided.
Article 5 (Assessment Categories)
- Conformity: The botanical species and fruit part, processing classification, content of fatty acids and other constituents, authenticity, oxidation and testing related to the processes used are consistent between lot documentation and labeling.
- Partial conformity: Botanical identification and principal composition can be verified, but traceability to the collection region or differentiation of oils in the finished product is insufficient, and a plan for supplementation exists.
- Nonconformity: The part used cannot be specified, the amounts of powder, extract and fatty acids are confused, or the possibility of admixture with other oils has not been evaluated.
Article 6 (Implementation)
The business operator may make a self-declaration of conformity using botanical receipt records, extraction process documentation, fatty acid and sterol composition tables, authenticity assessments and stability test results. Upon application, the Council may verify traceability from the labeled fruit raw material to reference documentation, collection lots and extraction lots. Reassessment shall be conducted whenever the place of origin, part used, extraction solvent, supplier, oils incorporated in the formulation or packaging is changed.
Supplementary Provisions
This Standard shall take effect on 3 September 2026.
Note: This Standard provides assessment criteria for information disclosure and quality management practices and does not guarantee the effects, efficacy or safety of individual products.
