520	3		_aThe 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 percent 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], ?-bisabolol, ?-farnesene, ?-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 percent, 51.84 percent, and 70.46 percent, 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 percent), suggesting a case of adulteration or substitution of the crude drug employed for manufacturing the product.
