Gc-ms and chemometric analysis of the essential oils obtained from mexican commercial chamomilla recutita teas

Chem Biodivers. 2024 Mar 19:e202400333. doi: 10.1002/cbdv.202400333. Online ahead of print.ABSTRACTThe essential oils prepared by hydrodistillation of twenty-one brands of German chamomile (S1-S21) commercialized in Mexico were analyzed by GS-MS. Altogether, twenty-four different compounds were identified in the analyzed samples, varying from 77 to 100 % of the total composition. Multivariate analyses were applied to explore similarity/dissimilarity and correlation between all samples; the results revealed a strong correlation among samples S4, S5, and S7-S21 due to the presence of (Z)-en-yn-dicycloether (Z- Tonghaosu), a-bisabolol, b-farnesene, b-eudesmol, and xanthoxylin. The samples S1-S3 and S6 were clustered separately. Samples S1, S3, and S6 were characterized by their higher content of bisabolol oxide A (38.78 %, 51.84 %, and 70.46 %, respectively) as most known chemotypes of German chamomile, but only S1 and S3 contained chamazulene. Finally, S2 differed from the others because of its high content of (E)-anethole (62.28 %), suggesting a case of adulteration or substitution of the crude drug employed for manufacturing the product.PMID:38502786 | DOI:10.1002/cbdv.202400333
