Abstract

Analytical Control and Antioxidative Activity of Different Teas in Serbia

Satureja montana, Ocimum basilicum, Camellia sinesis, Saliva officinalis, Althaea officinalis, Thymus camphoratus, Rosmarinus officinalis, Mentha piperita and Mountain tea were investigated for their quality (ash and moisture contents), as well as for chemical profile. HPLC analysis was applied to determine saccharide, vitamin C and caffeine contents in all teas samples. Obtained results demonstrated high quality of all tea samples (moisture of all samples was below 12%), while chemical analysis revealed presence of glucose, fructose, sucrose, vitamin C and caffeine in tested materials. Exception was Ocimum basilicum, where only glucose was detected and quantified. The results of total antioxidant acticity showed that tea of Althaea officinalis have the highest content (130.72 ± 0.54 mg AA/G ) and the lowest content have Satureja montana (106.05 ± 0.40 mg AA/G). The highest content of polyphenol was detected in Satureja montana.
