Overview
ISO 13171:2016/Amd 1:2025 is the first amendment to the international standard for the essential oil of oregano derived from Origanum vulgare L. subsp. hirtum (Link) Ietsw. Published by the International Organization for Standardization (ISO), this document updates analytical methods and specifications related to oregano essential oil. The amendment refines chromatographic profiling techniques to ensure more accurate identification and quality control of oregano oils, which are prized for their aromatic, culinary, and therapeutic properties.
This standard is developed by ISO Technical Committee ISO/TC 54, which focuses on essential oils, ensuring stakeholders have a globally harmonized reference for evaluating the composition and purity of oregano essential oil. It is applicable for producers, quality control laboratories, researchers, and regulatory bodies involved in essential oil manufacture and certification.
Key Topics
-
Chromatographic Profile Update: Amendment 1 replaces Figure A.2 with a detailed chromatogram of oregano essential oil analyzed on a polar column (DBWax). This chromatogram aids in identifying key chemical constituents based on retention time and flame ionization detector response.
-
Chemical Constituents Identification: The amendment lists eleven principal peaks associated with major oregano oil components, such as:
- α-pinene
- α-thujene
- myrcene
- α-terpinene
- γ-terpinene
- p-cymene
- linalool
- β-caryophyllene
- terpinen-4-ol
- thymol
- carvacrol
-
Operating Conditions for Analysis: The amendment specifies standardized gas chromatography conditions including column type, oven temperature programming, injector and detector temperatures, carrier gas type and flow rate, injection volume, and split ratio. These parameters enable reproducibility and comparability of essential oil analyses internationally.
-
Quality and Compliance: The inclusion of amendment Amd 1:2025 underlines ISO’s commitment to maintaining up-to-date analytical methodologies, reflecting advances in instrumentation and ensuring that oregano essential oil products meet consistent quality benchmarks worldwide.
Applications
-
Quality Control in Essential Oil Production: Producers can apply this standard to authenticate oregano essential oil batches, monitor consistency, and assure compliance with international market requirements.
-
Regulatory Compliance and Certification: Regulatory bodies and certification organizations can reference this amendment to establish compliance criteria for trading and labeling oregano essential oils, helping to prevent adulteration and fraud.
-
Research and Development: Scientists and product developers use the standardized chromatographic data and analysis parameters as a baseline for exploring new oregano cultivars, extraction methods, and applications in pharmaceuticals, cosmetics, and food industries.
-
Supply Chain Transparency: Importers, exporters, and distributors rely on ISO 13171 and its amendments to verify product authenticity and support traceability along the supply chain.
