Content and structural characteristics of flavanols in each section were investigated and the following results were obtained. i) Much amount of flavanols is contained in all sections of the inner bark of both species and their concentrations reach to over 10 percent by the weight of oven-dried barks. ii) Production of flavanols begins at the earlier stage of bark formation because much amount of flavanols is accumulated in the inside section of the inner barks near cambium. iii) In the inner barks of both species, there is no evidence suggesing secondary structural changes, i.e., changes of molecular weight distribution and changes of the proportion of the stereoisomers. Therefore, differences of physiological factors among each section of the inner barks show less effect on the structural characteristics of flavanols. iv) The content of extractable flavanols decreases significantly in the outer barks of both species. This observation suggests that most of flavanols are coverted into insoluble form in the outer barks. The structural characteristics of flavanols in the outer barks of Cryptomeria japonica are different significantly from those in the inner bark of the same species on their molecular weight distributions and on the bonding modes among flavanol units.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"55657","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SAMEJIMA, Masahiro"}]},{"nameIdentifiers":[{"nameIdentifier":"55658","nameIdentifierScheme":"WEKO"}],"names":[{"name":"YOSHIMOTO, Tomotaka"}]}]},"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_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"610","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Tokyo University Forests"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学農学部林産学科"},{"subitem_text_value":"Department of Forest Products, Faculty of Agriculture, University of Tokyo."}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"鮫島, 正浩"}],"nameIdentifiers":[{"nameIdentifier":"55655","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"善本, 友孝"}],"nameIdentifiers":[{"nameIdentifier":"55656","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":"2017-06-12"}],"displaytype":"detail","filename":"esrh072002.pdf","filesize":[{"value":"534.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh072002.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25620/files/esrh072002.pdf"},"version_id":"de8810f4-9eef-4087-955e-c0f31526ff90"}]},"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":"スギおよびアカマツ樹皮中でのフラバノール類の蓄積ならびにその構造上の変化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"スギおよびアカマツ樹皮中でのフラバノール類の蓄積ならびにその構造上の変化"}]},"item_type_id":"4","owner":"1","path":["2598","2597"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25620","relation_version_is_last":true,"title":["スギおよびアカマツ樹皮中でのフラバノール類の蓄積ならびにその構造上の変化"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:48.752404+00:00"}
