Major component · the claim says “among their principal biologically active compounds”
Essential oils of chamomile from several European countries had bisabolol oxide A, α-bisabolol, bisabolol oxide B, cis-enyne-bicycloether, bisabolone oxide A and chamazulene among their principal biologically active compounds, with bisabolol oxide A predominant in 8 of 13 samples.
Scope: Thirteen samples of the dried herb; composition varies with origin, and the study does not describe smell. CLM-CHAMOMILE-001 ↗

WHAT THIS MEANS
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.
