Antimicrobial and antioxidant potentials, total phenolic contents of some herbal waters
Abstract
The aim of the actual study is to evaluate antimicrobial and antioxidant potentials, total phenolic contents of thyme (Thymus sp.), myrtle (Myrtus communis L.), eucalyptus (Eucalyptus globulus L.) and rosemary herbal waters (Rosmarinus officinalis L.). They were bought a retailer in Giresun. In the studies, it was determined that only thyme water exhibited antimicrobial activity in all herbal waters. Streptomycine, tetracycline and nystatin which were synthetic antimicrobials demonstrated higher activity than studied herbal waters. Moreover; total flavonoid contents of the tested waters ranges from 50.19±0.0038 µL CE/mL to 126.15±0.004 µL CE/mL. The highest and the lowest total phenolic contents were detected in the thyme water and the eucalyptus water as 688.18±0.009 µL GAE/mL and 24.54±0.0008 µL GAE/mL, respectively. DPPH and ABTS radical scavenging activities of the herbal waters exhibited a dose dependent manner and increased with increasing conentrations. As a result of this study, it was concluded that thyme water could be an alternative to synthetic antimicrobial agents and thyme water, myrtle water, eucalyptus water and rosemary waters might be an alternative to synthetic antioxidative agents. Hence, further and detailed investigations are needed to determine active constituents in the herbal waters.
