Indirubin could be measured by GC/MS after replacing the active hydrogen on the amino group with -Si(CH3)3 or -Si(CH3)2C2H5 groups. However, peak tailing was observed and the quantitative and detection limits were not sensitive enough for practical use. Indirubin silylated at four sites was observed under the reaction conditions as follows; solvent dichloromethane: acetone (8 : 2), 90°C reaction temperature, 1 hr reaction time, BSTFA derivative, pyridine catalyst. The color of the solution changed from red to colorless. Retention time appeared to be faster and the peak shape improved. Under these conditions, the quantitative and detection limits of indirubin were 5 ppb and 0.1 ppb, respectively.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Journal of Health Science v.49(1) p.88-90, 2003","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"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/jhs.49.88","subitem_relation_type_select":"DOI"}}]},"item_2_relation_42":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://dx.doi.org/10.1248/jhs.49.88"}]}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11316464","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13449702","subitem_source_identifier_type":"ISSN"}]},"item_2_source_id_8":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"1347-5207","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":"Takao, Yuji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamashita, Kohei"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kohra, Shinya"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Inudo, Makiko"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nagae, Masaki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tominaga, Nobuaki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ishibashi, Yasuhiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sekizawa, Jun"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Miyairi, Shinichi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Arizono, Koji"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-24"}],"displaytype":"detail","filename":"JHS49_88.pdf","filesize":[{"value":"128.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JHS49_88.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/23152/files/JHS49_88.pdf"},"version_id":"f74f69cf-8be5-4a97-99a5-f1a7d9072982"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"indirubin","subitem_subject_scheme":"Other"},{"subitem_subject":"silylation","subitem_subject_scheme":"Other"},{"subitem_subject":"GC/MS","subitem_subject_scheme":"Other"},{"subitem_subject":"N","subitem_subject_scheme":"Other"},{"subitem_subject":"O-bis(trimethylsilyl) trifluoroacetamide","subitem_subject_scheme":"Other"},{"subitem_subject":"derivative","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":"High Sensitivity Analysis of Indirubin by Silylation Using GC/MS","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"High Sensitivity Analysis of Indirubin by Silylation Using GC/MS"}]},"item_type_id":"2","owner":"2","path":["56"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-10-12"},"publish_date":"2007-10-12","publish_status":"0","recid":"23152","relation_version_is_last":true,"title":["High Sensitivity Analysis of Indirubin by Silylation Using GC/MS"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T00:58:47.770328+00:00"}
