Are there any essential oils like plants

Hello my dears,
Today I want to address the subject of aromatherapy and perfumes. Yes, everyone will now roll their eyes and say these are two pairs of shoes. But that interests me now because I don't actually know what the volume percentage of essential oils in perfumes (EDT) normally is.
My question is based on this study, which suggests an improvement in cognitive performance under the influence of rosemary essential oil.
An excerpt from the book "Essential Oil Safety" (2nd edition, pages 407 and 408):

Rosmarinus officinalis
L. Borneol CT: 1.8 cineole 20.0%
L. Bornyl acetate CT: 1.8 cineole 6.8-13.6%
L. Camphor CT: 1.8 cineole 17.0-22.5%
L. Bornyl acetate CT: 1.8 cineole 6.8-13.6%
L. 1,8-Cineole CT: 1.8 Cineole 39.0-57.7%
L. β-Myrcene CT: 1.8 cineole 4.2-5.6%


Are there perfume manufacturers who state which phenotypes they use in the perfumes? I once read that many manufacturers of perfumes use chemically produced (fragrance) substances in the laboratory¹ rather than expensive essential oils. What is it? And if there is less to it - which I suspect - the concentration of essential oils in (alcohol-based) perfumes should still be vanishingly low.

I'm sure there are a few people here who can tell me more about it.
And just in advance: I realize that perfumes are not medicinal and that aromatherapy should not replace a visit to the doctor. Nevertheless, if such a perfume has certain proportions of essential oils that lift the mood or, as described above, the concentration, I would find that very welcome.
I look forward to answers.

Best regards,
your newcomer to the scent
