Oregano dust Origanum onites

Target compounds: Carvacrol, thymol, antioxidant essential oil. Compound class: Polyphenols. Measured and published by AltraProcess, the process development division of AltraFlora.

Summary

Material

The starting material is oregano dust (Origanum onites) — the fine fraction left over from oregano processing, normally treated as a low-value residue. The dust was extracted with supercritical CO2 to recover its volatile, terpene-rich fraction.

Sample preparation

A 10 mL sample of the extract was taken, from which 10 µL was sub-sampled for analysis and diluted 100-fold in hexane.

Analysis

The diluted extract was analysed by GC-MS under the laboratory's in-house method AF-LABGC002, identifying the constituents of the profile and their relative abundances from retention times and mass spectra. The same run was used to screen the extract for additives, adulterants and contaminants.

Measured yields, compositions and chromatograms are reported in the full application note (PDF above).
