We have studied the hitherto unknown oxidative metabolism of secoisolariciresinol and matairesinol in hepatic microsomes from untreated and Aroclor 1254-induced Wistar rats and from humans. Five oxidative metabolites of secoisolariciresinol and 10 oxidative metabolites of matairesinol were detected in rat liver microsomes, and their chemical structures were elucidated. The pathways in the metabolism of both secoisolariciresinol and matairesinol included aliphatic and aromatic hydroxylation, whereas oxidative demethylation was only observed for matairesinol. Human hepatic microsomes were able to metabolize secoisolariciresinol whereas matairesinol was only poorly metabolized. This study clearly shows that secoisolariciresinol and matairesinol are substrates of cytochrome P450-mediated metabolism. However, from preliminary experiments with rats dosed orally with secoisolariciresinol and matairesinol, it appears that the intestinal absorption and subsequent oxidative metabolism of these plant lignans occur only to a very small extent due to the highly efficient conversion of secoisolariciresinol and matairesinol to the mammalian lignans enterodiol and enterolactone by the gut microflora.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-53427","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"\"METZLER M,UNIV KARLSRUHE,INST FOOD CHEM & TOXICOL DEPT CHEM & BIOSCI;POB 6980;D-76128 KARLSRUHE, GERMANY.Manfred.Metzler@chemie.uni-karlsruhe.de\"","annee":"2003","mois":"10","numero":"51:21","page":"6317-6325","auteurs":[{"ID":53424,"post_author":"0","post_date":"2018-12-04 06:19:00","post_date_gmt":"2018-12-04 05:19:00","post_content":"","post_title":"Honig","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"honig","to_ping":"","pinged":"","post_modified":"2018-12-04 06:19:00","post_modified_gmt":"2018-12-04 05:19:00","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/honig\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":6384,"post_author":"0","post_date":"2018-12-03 17:37:48","post_date_gmt":"2018-12-03 16:37:48","post_content":"","post_title":"Sabine E Kulling","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"sabine-e-kulling","to_ping":"","pinged":"","post_modified":"2018-12-03 17:37:48","post_modified_gmt":"2018-12-03 16:37:48","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/sabine-e-kulling\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":53425,"post_author":"0","post_date":"2018-12-04 06:19:00","post_date_gmt":"2018-12-04 05:19:00","post_content":"","post_title":"Metzler","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"metzler","to_ping":"","pinged":"","post_modified":"2018-12-04 06:19:00","post_modified_gmt":"2018-12-04 05:19:00","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/metzler\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":53426,"post_author":"0","post_date":"2018-12-04 06:19:01","post_date_gmt":"2018-12-04 05:19:01","post_content":"","post_title":"Niemeyer","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"niemeyer","to_ping":"","pinged":"","post_modified":"2018-12-04 06:19:01","post_modified_gmt":"2018-12-04 05:19:01","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/niemeyer\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":1648,"post_author":"0","post_date":"2018-12-03 16:01:16","post_date_gmt":"2018-12-03 15:01:16","post_content":"","post_title":"Journal of agricultural and food chemistry","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"journal-of-agricultural-and-food-chemistry","to_ping":"","pinged":"","post_modified":"2018-12-03 16:01:16","post_modified_gmt":"2018-12-03 15:01:16","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/journal-of-agricultural-and-food-chemistry\/","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) -
