| Abstract:
The chemical and microbiological investigations were carried out on the samples of commercial chamomile tea, during 18 months, stored in warehouse. The essential oil content ranged from 0.24 to 0.50%. The main compound in all samples was bisabolol oxide A (33.46–48.48%). The amount of (-)-  -bisabolol, bisabolol oxide B, bisabolon oxide, farnesene, spathulenol, chamazulene as well as en-in-dicycloether were determined too.
Total bacteria count ranged from 4.0x104 - 4.6 x 106/ g d.m.
Dominant bacteria belong to Bacillus genus, but also the genus Micrococcus and Staphylococcus were found. Escherichia coli as pathogenic bacteria was detected.
The content of fungi and yeast were determined.
