Abstract

In this study, antioxidant activities of aqueous extracts from of Thymus longicaulis subsp. chaubardii (Rchb.f.) Jalas and T. longicaulis subsp. longicaulis C. presl were investigated. Infusion and decoction methods were used to prepare aqueous extracts. 1, 1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging, β-carotene linoleic acid and CUPRAC methods were used to determined antioxidant activities. Aqueous extracts of species exhibited good antioxidant activity. Especially, higher antioxidant capacity was found in decoction extracts compared to infusion extracts for all methods.
