Total phenolic content and antioxidant activity of Thymus vulgaris, Curcuma longa, propolis and their mixtures.

The current study, we investigated phenolic content and antioxidant activity of ethyl acetate and dichloromethane extracts of thyme, turmeric, propolis and their mixtures. The highest and the lowest phenolic contents were found in ethyl acetate extract of propolis (214.94±0.023 μg GAE/mL) and dichloromethane extract of thyme (21.02±0.013 μg GAE/mL). Total antioxidant capacity of ethyl acetate extracts ranges from 127.15±0.031 μg AAE/mL and 232.2±0.028 μg AAE/mL; dichloromethane extracts ranges from 61.6±0.019 μg AAE/mL and 159.95±0.035 μg AAE/mL. CUPRAC activity and DPPH radical scavenging activity of ethyl acetate extracts are higher than dichloromethane extracts. According to the obtained results, it can be said that propolis, thyme and turmeric could be an alternative to synthetic antioxidants. [ABSTRACT FROM AUTHOR]
