Berries native to Western Canada were analyzed for total anthocyanins, total phenolics, and trolox equivalent antioxidant activity (TEAC). Values ranged from 1.60 to 9.55 mmol trolox equivalent per 100 g fresh mass. Anthocyanin content ranged from 41.6 (in red twinberries) to 1081 mg cyanidin-3-glucoside equivalents per 100 g fresh mass (in honeysuckle fruits). Honeysuckle fruits contained the highest amount of total polyphenols, 1111 mg gallic acid equivalents per 100 g, among analyzed fruits. Additionally, anthocyanins in the investigated berries were identified and characterized by HPLC – electrospray ionization – tandem mass spectrometric method coupled with diode array detection. The number of anthocyanins varied from 4 in saskatoon berries (Amelanchier alnifolia Nutt.) to 20 in bilberries (Vaccinum myrtilloides Michx.). In all the samples analyzed, 6 common anthocyanidins:, cyanidin, delphinidin, pelargonidin, petunidin, peonidin, and malvidin, were found. Half the analyzed berries contained acylated anthocyanins, but a significant amount was found only in bilberries. The analyzed berry seed oils contained high amounts of unsaturated fatty acids (over 90%), but only the golden currant seed oil contained gamma-linolenic acid.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-45264","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Olds College School of Innovations, Olds College, 4500 50 Street, Olds, AB T4H 1R6, Canada. abakowska@oldscollege.ca","annee":"2007","mois":"11","numero":"85:11","page":"1139-52","auteurs":[{"ID":45260,"post_author":"0","post_date":"2018-12-04 03:39:12","post_date_gmt":"2018-12-04 02:39:12","post_content":"","post_title":"Bakowska-barczak","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"bakowska-barczak","to_ping":"","pinged":"","post_modified":"2018-12-04 03:39:12","post_modified_gmt":"2018-12-04 02:39:12","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/bakowska-barczak\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":45261,"post_author":"0","post_date":"2018-12-04 03:39:13","post_date_gmt":"2018-12-04 02:39:13","post_content":"","post_title":"Marianchuk","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"marianchuk","to_ping":"","pinged":"","post_modified":"2018-12-04 03:39:13","post_modified_gmt":"2018-12-04 02:39:13","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/marianchuk\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":45262,"post_author":"0","post_date":"2018-12-04 03:39:14","post_date_gmt":"2018-12-04 02:39:14","post_content":"","post_title":"Kolodziejczyk","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"kolodziejczyk-2","to_ping":"","pinged":"","post_modified":"2018-12-04 03:39:14","post_modified_gmt":"2018-12-04 02:39:14","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/kolodziejczyk-2\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":45263,"post_author":"0","post_date":"2018-12-04 03:39:14","post_date_gmt":"2018-12-04 02:39:14","post_content":"","post_title":"CANADIAN JOURNAL OF PHYSIOLOGY AND PHARMACOLOGY","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"canadian-journal-of-physiology-and-pharmacology","to_ping":"","pinged":"","post_modified":"2018-12-04 03:39:14","post_modified_gmt":"2018-12-04 02:39:14","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/canadian-journal-of-physiology-and-pharmacology\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"\nSurvey of bioactive components in Western Canadian berries -
