MOLECULE
Named in 2 VERIFIED claims about 2 Atlas entries: Pine Needles, Black Pepper.
Major component · the claim says “contained high percentages of”
Essential oils from the needles and green cones of four pine species contained high percentages of α-pinene, (E)-caryophyllene, limonene, germacrene D, myrcene and δ-3-carene.
Scope: Needle and cone oils of four Pinus species from one region, reported together; composition, not odour potency. CLM-PINENEEDLE-001 ↗
Major component · the claim says “dominated by”
Essential oils of black pepper fruits from Madagascar and Brazil were dominated by α-pinene, sabinene, β-pinene, δ-3-carene, limonene and β-caryophyllene, and their relative amounts grouped by origin.
Scope: Composition of hydrodistilled essential oils, not the odour potency of each compound; origin and processing change the profile. CLM-PEPPER-001 ↗
BQOFWKZOCNGFEC-UHFFFAOYSA-NChecked against PubChem and Wikidata on 2026-10-02 (identifier check run 37063263965). Every name SmellBook uses must resolve to the same single PubChem compound.
SmellBook lists a molecule only where a VERIFIED claim names it, in the role and scope that claim states. A molecule reported in a smell's evidence is not the whole smell: most smells come from many compounds together, and the studies measured particular samples, such as one cultivar, an essential oil or a cooked product.
