Thus, facile methods to prepare black tea constituents were desired. Treatment of epigallocatechin gallate with copper(II) chloride efficiently afforded an unstable quinone dimer, dehydrotheasinensin A, and subsequent treatment with ascorbic acid stereoselectively yielded theasinensin A. The latter is a dimer with an R-biphenyl bond, one of the major polyphenols found in black tea. The method is simpler and more effective than enzymatic preparation.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"CHEMICAL & PHARMACEUTICAL BULLETIN, 59(9), pp.1183-1185; 2011","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.59.1183","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c) 2011 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":"13475223","subitem_source_identifier_type":"ISSN"}]},"item_2_text_62":{"attribute_name":"出版者別言語","attribute_value_mlt":[{"subitem_text_value":"日本薬学会"}]},"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":"Shii, Takuya"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Miyamoto, Makoto"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsuo, Yosuke"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tanaka, Takashi"}],"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":"2020-12-22"}],"displaytype":"detail","filename":"CPBul59_1183.pdf","filesize":[{"value":"652.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"CPBul59_1183.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/12063/files/CPBul59_1183.pdf"},"version_id":"2353f65d-1381-43dc-97bb-e7b44ea8cd6b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Black tea","subitem_subject_scheme":"Other"},{"subitem_subject":"Copper(II) chloride","subitem_subject_scheme":"Other"},{"subitem_subject":"Dehydrotheasinensin A","subitem_subject_scheme":"Other"},{"subitem_subject":"Epigallocatechin gallate","subitem_subject_scheme":"Other"},{"subitem_subject":"Theasinensin A","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":"Biomimetic One-Pot Preparation of a Black Tea Polyphenol Theasinensin A from Epigallocatechin Gallate by Treatment with Copper(II) Chloride and Ascorbic Acid","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Biomimetic One-Pot Preparation of a Black Tea Polyphenol Theasinensin A from Epigallocatechin Gallate by Treatment with Copper(II) Chloride and Ascorbic Acid"}]},"item_type_id":"2","owner":"2","path":["74"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-10-31"},"publish_date":"2011-10-31","publish_status":"0","recid":"12063","relation_version_is_last":true,"title":["Biomimetic One-Pot Preparation of a Black Tea Polyphenol Theasinensin A from Epigallocatechin Gallate by Treatment with Copper(II) Chloride and Ascorbic Acid"],"weko_creator_id":"2","weko_shared_id":2},"updated":"2023-05-15T19:05:41.014510+00:00"}
