Optimization of ultrasonic-assisted extraction of anthocyanins from Prunus yedoensis fruit and evaluation of antioxidant and anti-inflammatory activity
Prunus yedoensis Matsumura is an important medicinal species in traditional Korean medicine, commonly employed for addressing a range of health issues. The fruit of Prunus yedoensis is abundant in anthocyanins, which possess strong antioxidant activity and effectively neutralize free radicals. In the present investigation, to optimize the extraction parameters for anthocyanins obtained from the fruit of P. yedoensis, response surface methodology was employed. Extraction time, ethanol concentration, and extraction temperature were carefully examined as key parameters to determine their influence on the yield and efficiency of anthocyanin extraction. Ultrasonic-assisted extraction extracted in this way showed higher antioxidant activity than conventional extract. In addition, the anti-inflammatory activity of UAE was confirmed, and changes in nitric oxide, inducible nitric oxide synthase, tumor necrosis factor alpha, and Interleukin-1 beta were observed. In conclusion, the extraction method of anthocyanins from P. yedoensis was optimized, and UAE extracted in this way had high antioxidant and anti-inflammatory activities.
期刊介绍：
The FSB journal covers food chemistry and analysis for compositional and physiological activity changes, food hygiene and toxicology, food microbiology and biotechnology, and food engineering involved in during and after food processing through physical, chemical, and biological ways. Consumer perception and sensory evaluation on processed foods are accepted only when they are relevant to the laboratory research work. As a general rule, manuscripts dealing with analysis and efficacy of extracts from natural resources prior to the processing or without any related food processing may not be considered within the scope of the journal. The FSB journal does not deal with only local interest and a lack of significant scientific merit. The main scope of our journal is seeking for human health and wellness through constructive works and new findings in food science and biotechnology field.
