After solvent partitioning of a black tea extract with the ethyl acetate and n-butanol, the two soluble fractions showed comparable inhibitory activities. Activity in the ethyl acetate fraction was mainly attributable to polyphenols with low-molecular weights, such as theaflavin gallates. On the other hand, the active substance in the n-butanol layer was ascertained to be a polymer-like substance. 1H- and 13C-NMR spectra showed signals arising from the flavan A-ring and galloyl groups, although signals due to flavan B-rings were not detected, suggesting that the polymer-like substances were generated by oxidative condensation of flavan B-rings, a result which was previously deduced from our results of in vitro catechin oxidation experiments. Enzymatic oxidation of epicatechin 3-O-gallate produced a similar polymer-like substance and suggested that condensation between a B-ring and galloyl groups was involved in the polymerization reaction.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Chemical & Pharmaceutical Bulletin v.56(3) p.266-272, 2008","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Pharmaceutical Society of Japan"}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1248/cpb.56.266","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c) 2008 The Pharmaceutical Society of Japan"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00602100","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00092363","subitem_source_identifier_type":"ISSN"}]},"item_2_source_id_8":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"1347-5223","subitem_source_identifier_type":"ISSN"}]},"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_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kusano, Rie"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Andou, Hisashi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujieda, Miho"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tanaka, Takashi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsuo, Yosuke"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kouno, Isao"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-23"}],"displaytype":"detail","filename":"CPBul56_266.pdf","filesize":[{"value":"645.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"CPBul56_266.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/19943/files/CPBul56_266.pdf"},"version_id":"e31feef0-1a06-4730-9833-495e8b62b7db"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"black tea","subitem_subject_scheme":"Other"},{"subitem_subject":"lipase","subitem_subject_scheme":"Other"},{"subitem_subject":"amylase","subitem_subject_scheme":"Other"},{"subitem_subject":"polyphenol","subitem_subject_scheme":"Other"},{"subitem_subject":"oxidation","subitem_subject_scheme":"Other"},{"subitem_subject":"thearubigin","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":"Polymer-Like Polyphenols of Black Tea and Their Lipase and Amylase Inhibitory Activities","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Polymer-Like Polyphenols of Black Tea and Their Lipase and Amylase Inhibitory Activities"}]},"item_type_id":"2","owner":"2","path":["74"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-06-30"},"publish_date":"2008-06-30","publish_status":"0","recid":"19943","relation_version_is_last":true,"title":["Polymer-Like Polyphenols of Black Tea and Their Lipase and Amylase Inhibitory Activities"],"weko_creator_id":"2","weko_shared_id":2},"updated":"2023-05-15T19:05:41.685432+00:00"}
