The content of selected flavonoids and phenolic acids was also determined by high-performance liquid chromatography with tandem mass spectrometry in the negative electrospray ionization mode.<\/p>\n<p><strong>RESULTS:<\/strong><br \/>\nFlavoured black teas contain significantly higher level of catechins, quercetin, and rutin, while the content of chlorogenic and caffeic acids as well as naringin and hesperidin was higher in fruit teas. Supplementation with these flavonoids could reduce blood glucose. In FC and DPPH assays, the antioxidant properties of studied tea infusion increases in the order: fruit tea &lt; flavoured black tea &gt; premium black tea, while in CUPRAC method, some aromatized teas exhibit the highest antioxidant properties. Tea infusions with nice smell of fruits would also support the human diet with some source of antioxidants.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-39319","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Chemistry, University of Warsaw, Pasteura 1, 02-093, Warsaw, Poland.","annee":"2011","mois":"12","numero":"50:8","page":"681-688","auteurs":[{"ID":39315,"post_author":"0","post_date":"2018-12-04 01:54:10","post_date_gmt":"2018-12-04 00:54:10","post_content":"","post_title":"Pekal","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"pekal","to_ping":"","pinged":"","post_modified":"2018-12-04 01:54:10","post_modified_gmt":"2018-12-04 00:54:10","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/pekal\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":39316,"post_author":"0","post_date":"2018-12-04 01:54:11","post_date_gmt":"2018-12-04 00:54:11","post_content":"","post_title":"Drozdz","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"drozdz","to_ping":"","pinged":"","post_modified":"2018-12-04 01:54:11","post_modified_gmt":"2018-12-04 00:54:11","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/drozdz\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":39317,"post_author":"0","post_date":"2018-12-04 01:54:13","post_date_gmt":"2018-12-04 00:54:13","post_content":"","post_title":"Biesaga","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"biesaga","to_ping":"","pinged":"","post_modified":"2018-12-04 01:54:13","post_modified_gmt":"2018-12-04 00:54:13","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/biesaga\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":39318,"post_author":"0","post_date":"2018-12-04 01:54:14","post_date_gmt":"2018-12-04 00:54:14","post_content":"","post_title":"Pyrzynska","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"pyrzynska","to_ping":"","pinged":"","post_modified":"2018-12-04 01:54:14","post_modified_gmt":"2018-12-04 00:54:14","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/pyrzynska\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":30026,"post_author":"0","post_date":"2018-12-03 23:26:51","post_date_gmt":"2018-12-03 22:26:51","post_content":"","post_title":"Eur J Nutr.","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"eur-j-nutr","to_ping":"","pinged":"","post_modified":"2018-12-03 23:26:51","post_modified_gmt":"2018-12-03 22:26:51","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/eur-j-nutr\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v23.6 (Yoast SEO v23.6) -
