We used leaf samples from three different lines (20835, 20675 and 20483) of the same Es, which have grown in different areas. The phenolic content in Es 20483 leaves was clearly correlated to the leaf height from the ground and the leaf area, although other Es lines were not. These results suggest that the same Es trees have different ways of producing or accumulating phenolics, depending on the growing environment. The leaves of Es 20483 line had approximately 25% phenolics, and those of the other lines had at least 15% phenolics based on dry weight. In all of the Es lines, gallic acid and their glycosides were the major phenolic compounds. In addition, they had a wide variety of compounds, such as flavanol, flavonol and chlorogenic acid. All of these phenolic compounds detected by HPLC are expected to be used as supplements and other uses, and thus the leaves of Es will be utilized as new biomass resources with high value.","subitem_description_type":"Abstract"}]},"item_4_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"53287","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Inagaki, Reina"}]},{"nameIdentifiers":[{"nameIdentifier":"53288","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ueki, Yuki"}]},{"nameIdentifiers":[{"nameIdentifier":"53289","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Terada, Tamami"}]},{"nameIdentifiers":[{"nameIdentifier":"53290","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Inoue, Hiroki"}]},{"nameIdentifiers":[{"nameIdentifier":"53291","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kamoda, Shigehiro"}]},{"nameIdentifiers":[{"nameIdentifier":"53292","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Samejima, Masahiro"}]}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院農学生命科学研究科附属演習林"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162451","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03716007","subitem_source_identifier_type":"ISSN"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The University of Tokyo Forests"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院農学生命科学研究科生物材料科学専攻"},{"subitem_text_value":"東京大学大学院農学生命科学研究科附属演習林樹芸研究所"},{"subitem_text_value":"Department of Biomaterial Scienecs, Graduate school of Agricultural and Life Sciences, The University of Tokyo"},{"subitem_text_value":"Arboricultural Research Institute, The University of Tokyo Forests, Graduate School of Agricultural and Life Sciences, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"稲垣, 怜那"}],"nameIdentifiers":[{"nameIdentifier":"53281","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"植木, 悠貴"}],"nameIdentifiers":[{"nameIdentifier":"53282","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"寺田, 珠実"}],"nameIdentifiers":[{"nameIdentifier":"53283","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"井上, 広喜"}],"nameIdentifiers":[{"nameIdentifier":"53284","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鴨田, 重裕"}],"nameIdentifiers":[{"nameIdentifier":"53285","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鮫島, 正浩"}],"nameIdentifiers":[{"nameIdentifier":"53286","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-09"}],"displaytype":"detail","filename":"esrh134006.pdf","filesize":[{"value":"979.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh134006.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25218/files/esrh134006.pdf"},"version_id":"ff9d0cad-0c49-403f-b138-0fb3877f7b96"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Eucalyptus saligna","subitem_subject_scheme":"Other"},{"subitem_subject":"葉","subitem_subject_scheme":"Other"},{"subitem_subject":"フェノール性成分","subitem_subject_scheme":"Other"},{"subitem_subject":"比色分析","subitem_subject_scheme":"Other"},{"subitem_subject":"HPLC","subitem_subject_scheme":"Other"},{"subitem_subject":"leaves","subitem_subject_scheme":"Other"},{"subitem_subject":"phenolics","subitem_subject_scheme":"Other"},{"subitem_subject":"colorimetric assay","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Eucalyptus saligna の葉に含まれるフェノール性成分の分析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Eucalyptus saligna の葉に含まれるフェノール性成分の分析"}]},"item_type_id":"4","owner":"1","path":["2474","2473"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-06-09"},"publish_date":"2016-06-09","publish_status":"0","recid":"25218","relation_version_is_last":true,"title":["Eucalyptus saligna の葉に含まれるフェノール性成分の分析"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:32.425439+00:00"}
