The major polyphenols were identified to be pyrogallol and 4′-hydroxyphenyl-3- (2′′,4′′,6′′-trihydroxyphenyl)-propan-2-ol, 3′,4′-dihydroxyphenyl-3-(2′′,4′′, 6′′-trihydroxyphenyl)-propan-2-ol, and 3′,4′,5′- trihydroxyphenyl-3-(2′′,4′′,6′′- trihydroxyphenyl)-propan-2-ol. The hydroxydiphenylpropan-2-ols were identical to the initial metabolites produced from green tea catechins by mammalian intestinal bacteria. In addition, an anaerobic mixed-fermentation experiment using lahpet-so and Japanese commercial green tea afforded two new catechin degradation products together with known compound bruguierol B and the above-mentioned catechin metabolites. Based on spectroscopic evidence, the structures of the new compounds were concluded to be 4-(2,5-dihydroxyhexyl) benzene-1,2-diol and (5S,8R)-6,7,8,9-tetrahydro-5-methyl-5・8-epoxy-5H- benzocycloheptene-2,3,4-triol. Interestingly, the production mechanism was deduced to be the inverse of the biosynthesis of the flavan-3-ol A ring.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Journal of Natural Medicines, 68(2), pp.459-464; 2014","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本生薬学会"}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s11418-014-0816-1","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c 2014 The Japanese Society of Pharmacognosy and Springer Japan."},{"subitem_rights":"The final publication is available at link.springer.com"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13403443","subitem_source_identifier_type":"ISSN"}]},"item_2_source_id_8":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"18610293","subitem_source_identifier_type":"ISSN"}]},"item_2_text_62":{"attribute_name":"出版者別言語","attribute_value_mlt":[{"subitem_text_value":"Japanese Society of Pharmacognosy"}]},"item_2_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Shii, Takuya"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Asada, Chiori"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsuo, Yosuke"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Saito, Yoshinori"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tanaka, Takashi"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-21"}],"displaytype":"detail","filename":"JNM68_459.pdf","filesize":[{"value":"198.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JNM68_459.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/5603/files/JNM68_459.pdf"},"version_id":"64ed6eef-8288-4e18-857e-4746b9084504"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Anaerobic fermentation","subitem_subject_scheme":"Other"},{"subitem_subject":"Catechin","subitem_subject_scheme":"Other"},{"subitem_subject":"Intestinal metabolism","subitem_subject_scheme":"Other"},{"subitem_subject":"Lahpet-so","subitem_subject_scheme":"Other"},{"subitem_subject":"Polyphenol","subitem_subject_scheme":"Other"},{"subitem_subject":"Tea","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Polyphenols in lahpet-so and two new catechin metabolites produced by anaerobic microbial fermentation of green tea","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Polyphenols in lahpet-so and two new catechin metabolites produced by anaerobic microbial fermentation of green tea"}]},"item_type_id":"2","owner":"2","path":["74"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-08-26"},"publish_date":"2014-08-26","publish_status":"0","recid":"5603","relation_version_is_last":true,"title":["Polyphenols in lahpet-so and two new catechin metabolites produced by anaerobic microbial fermentation of green tea"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T03:02:34.083331+00:00"}
