VERIFIED CLAIM

Compounds with the greatest impact on rosemary essential oil odour

In essential oils from six rosemary genotypes of different geographical origin, one sample each, flavour dilution factors from aroma extract dilution analysis and odour activity values consistently indicated that 1,8-cineole, α-pinene, 1-hexen-3-one, β-damascenone, 1-octen-3-one, linalool and fenchol had the greatest impact on the overall odour.

Scope

Essential oils of six rosemary (Salvia rosmarinus) genotypes, a single oil sample per genotype; not fresh or dried leaves; the abstract gives no chemotypes; not every rosemary oil.

How this was found

Odour analysis with human assessors. People smelled the separated compounds or the material itself (for example gas chromatography–olfactometry, dilution analysis, recombination or a sensory panel).

Source: primary study; sensory or perception work.

Studied: essential oils of six rosemary genotypes, by gas chromatography–olfactometry and odour activity values.

This describes how the source's evidence was produced. What the claim itself covers is its scope, above; how SmellBook checked the claim, where it could, is the next section.

How this claim was checked

SmellBook checked this claim against the source's own words, so that the claim says no more than the source supports. This does not repeat or re-test the study itself.

The statement the claim rests on was found word for word in the abstract fetched from the named service, and an editor read the full abstract against every part of the claim. Abstract from Europe PMC (ebi.ac.uk/europepmc).
