        Effects of Extraction Methods on the Phenolic Compounds Contents and Antioxidant Capacities of Cinnamon Extracts

        Eva Dvorackova,Marie Snoblova,Lucie Chromcova,Petr Hrdlicka 한국식품과학회 2015 Food Science and Biotechnology Vol.24 No.4

        Extraction of the phenolic compounds, cinnamic and benzoic acid derivates, from Cinnamonum cassia (Nees & T.Nees) J.Presl was carried out. Classical solvent extraction, ultrasonication, maceration, and shaking methods were compared. Phenolic compounds were identified based on ultrahigh-performance liquid chromatography with photodiode array detector. The optimum solvent percentage was 60% (v/v) ethanol (EtOH) in a ratio of 1:20 with the cinnamon sample weight. The optimum extraction time was 90 min, and the optimum extraction temperature was 50oC. Under optimized conditions, the highest phenolic contents were 2.263±0.089 mg/g of free acids for sinapic acid, and the contents of cinnamic acid were 0.103±0.031 mg/g of free acids. The antioxidant capacity of the extract produced using the best extraction conditions was 14.337±4.662 mmol/g and the total phenolic content was 1.918±0.528 mmol/g.
