In all the parts of ginkgo trees examined, green and fallen leaves, wood, outer and inner barks, roots, and albumens, ginkgolides were detected. Fallen leaves had rather less ginkgolides than green leaves. Inner bark collected in April contained substantial amounts of ginkgolides, whereas outer bark had half the amount and wood had far less. In the roots of young trees collected in October, the amount of total ginkgolides was about three times as high as that of green leaves. In albumens, ginkgolide B was the main ingredient, and ginkgolides A and C were far less. Ginkgolide production was examined in cultured cells derived from embryo, petiole and cambium. Several cultured cells produced ginkgolide B, but the concentration was far less than any part of mother plants. Embryo-derived cultured cells generally produced ginkgolide B, while petiole- and cambium-derived calli showed poorer results. Greening of the cultured cells under illumination seemed to have no connection with ginkgolide production.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54419","nameIdentifierScheme":"WEKO"}],"names":[{"name":"井上, 広喜"}]},{"nameIdentifiers":[{"nameIdentifier":"54420","nameIdentifierScheme":"WEKO"}],"names":[{"name":"鴨田, 重裕"}]},{"nameIdentifiers":[{"nameIdentifier":"54421","nameIdentifierScheme":"WEKO"}],"names":[{"name":"寺田, 珠実"}]},{"nameIdentifiers":[{"nameIdentifier":"54422","nameIdentifierScheme":"WEKO"}],"names":[{"name":"佐分, 義正"}]}]},"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":"Department of Biomaterial Sciences, Graduate School of Agricultural and Life Sciences, The University of Tokyo"},{"subitem_text_value":"University Forest in Hokkaido, Faculty of Agriculture, The University of Tokyo"},{"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":"東京大学農学部附属演習林北海道演習林"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"INOUE, Hiroki"}],"nameIdentifiers":[{"nameIdentifier":"54415","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"KAMODA, Shigehiro"}],"nameIdentifiers":[{"nameIdentifier":"54416","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"TERADA, Tamami"}],"nameIdentifiers":[{"nameIdentifier":"54417","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SABURI, Yoshimasa"}],"nameIdentifiers":[{"nameIdentifier":"54418","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":"esrh101008.pdf","filesize":[{"value":"466.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh101008.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25386/files/esrh101008.pdf"},"version_id":"521b9c98-6b75-49aa-9b99-836d7a82e9d3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ギンコライド","subitem_subject_scheme":"Other"},{"subitem_subject":"イチョウ","subitem_subject_scheme":"Other"},{"subitem_subject":"ginkgolide","subitem_subject_scheme":"Other"},{"subitem_subject":"Ginkgo biloba","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Ginkgolide Production in Ginkgo biloba Trees and Cultured Cells","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Ginkgolide Production in Ginkgo biloba Trees and Cultured Cells"}]},"item_type_id":"4","owner":"1","path":["2540","2539"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25386","relation_version_is_last":true,"title":["Ginkgolide Production in Ginkgo biloba Trees and Cultured Cells"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:00:56.013712+00:00"}
