Název v původním jazyce

Antioxidační aktivita aroamtických rostlin

Popis výsledku v původním jazyce

Aromatic plants contain important biologically active compounds such as antioxidants (polyphenols, vitamins, minerals). To important aromatic plants belong chamomile, lavender, lemon balm, oregano, sage, and agrimony, that were analyzed in our work for polyphenol content (PP) and antioxidant capacity (AC). Photometric method with Folin-Ciocalteu reagent was used for PP determination of aromatic plants extracts. The content of PP was evaluated for extracts (10.42 – 93.35 mg GAE.g-1) in this order: oregano and lemon balm, further lavender, sage and agrimony, and the lowest for chamomile. Quantity of polyphenols and AC are affected by several factors, such as temperature of extraction. Higher temperature of extraction resulted in higher amount of extracted polyphenols and also higher AC. AC was assessed by photometric method with DPPH solution (23.32 – 146.97 mg AAE.g-1). The highest antioxidant capacity was evaluated for oregano extract, that has also the biggest value of PP. Lower AC showed extracts of lemon balm, further extracts of agrimony, sage, lavender, and the lowest AC was determined for chamomile. Oregano and lemon balm are therefore plants with higher content of biologically active compounds.
