In order to compensate for the insufficiency of wild Glycyrrhiza resources with cultivated ones, the cultivation study of Glycyrrhiza uralensis has been carried out since 1998 and is still continuing. The cultivation field is located in the eastern region of Nei-Meng-gu, inner Mongolia, which is the habitat of G. uralensis and the major source of Dongbei-Gancao, Tohoku-Kanzo in Japanese. The seeds of G. uralensis were sown on May in 1998 and seedling roots were transplanted to the field the next May. The glycyrrhizin (GL)-content of 4-year-old lateral roots, which were newly grown from the transplanted seedling taproot, exceeded the Japanese Pharmacopoeia XIV standard (2.5% or more GL). This is the first report to examine GL-content of G. uralensis cultivated in northeast China related to cultivation years. However, since GL-content (2.81 ± 0.76%) of 4-year-old lateral roots was at a low level yet, further examinations on improvement of cultivation conditions are in progress to obtain suitable length and thickness of lateral roots, high GL-contents and adequate ingredients-composition similar to those of wild Glycyrrhiza roots currently in use.\n 中国において野生甘草(Gancao)の採集が砂漠化を誘発するために2000年に制限する通知が出され,栽培甘草の実用化が強く望まれるようになっている。本研究は,地球環境を保全し甘草資源を確保(野生甘草の不足分を栽培甘草で補填)する観点から企画された。本論文の特徴は,Glycyrrhiza uralensis Fisch.を内蒙古自治区の東部(元宝山区古山鎮西六家村:東北甘草の産地)において栽培した点にある。なお試験植物がG.uralensisであることは,3-4年目の夏に開花した花と果実および小葉の形態から確認した。5月に播種し翌年の5月に苗を堀り上げ根を20-25cmに切りそろえた後,移植した。移植根から新たに生育した4年目の側根(lateralroots)のglycyrrhizin(GL)含量が,日本薬局方の基準値(JPXIV:GLを2.5%以上含む)を越えることが明らかになった。中国の東北甘草の生産地域で栽培されたG.uralensisのGL含量を栽培年数と関連付けて検討したのは,本論文が初めてである。今回の実験によって,栽培甘草が薬用資源として利用できる可能性が高まった。しかしながら,4年目のGL含量(2.81±0.76%)は日本市場の東北甘草(Dongbei-Gancao)の平均値(5.16±1.00%)と比べて満足できる値に達していない。優良種苗の選抜や栽培方法の改良など今後の検討が必要である。この栽培実験と併行して中国の甘草生産地において栽培されたGlycyrrhiza根を調査したところ,JPXIV基準に適合する物は得られなかった。なお,西北地域で蒐集した試料は移植せずに5-6年間栽培された主根(tap-roots)であった。今回我々が実施した栽培実験においてJPXIVの基準に適合したのは,移植後に主根から生育した側根(lateralroots)であった。移植の有無や移植時期が側根の成長やGL含量に及ぼす影響に関しては,現在も内蒙古東部の畑において検討中である。","subitem_description_type":"Abstract"}]},"item_2_description_40":{"attribute_name":"資源タイプ(DSpace)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"和漢医薬学会"}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"rights: 本文データは和漢医薬学会の許諾に基づき複製したものである"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10486121","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13406302","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":"Yamamoto, Yutaka"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tani, Tadato"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"detail","filename":"20020302.pdf","filesize":[{"value":"889.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"20020302.pdf","url":"https://toyama.repo.nii.ac.jp/record/5281/files/20020302.pdf"},"version_id":"65f62686-d512-4700-8805-9205012f1ecb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Glycyrrhiza uralensis","subitem_subject_scheme":"Other"},{"subitem_subject":"cultivation","subitem_subject_scheme":"Other"},{"subitem_subject":"glycyrrhizin","subitem_subject_scheme":"Other"},{"subitem_subject":"HPLC","subitem_subject_scheme":"Other"},{"subitem_subject":"licorice","subitem_subject_scheme":"Other"},{"subitem_subject":"Gancao","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":"Growth and glycyrrhizin contents in Glycyrrhiza uralensis roots cultivated for four years in eastern Nei-Meng-gu of China","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Growth and glycyrrhizin contents in Glycyrrhiza uralensis roots cultivated for four years in eastern Nei-Meng-gu of China"}]},"item_type_id":"2","owner":"3","path":["648"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-01-23"},"publish_date":"2008-01-23","publish_status":"0","recid":"5281","relation_version_is_last":true,"title":["Growth and glycyrrhizin contents in Glycyrrhiza uralensis roots cultivated for four years in eastern Nei-Meng-gu of China"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-11-06T04:44:22.673316+00:00"}
