The present report was carried out to check the optical purity of terpinen-4-ol by means of the integration for signal of 4R-and 4S-terpinen-4-ol in NMR spectra using a chiral shift reagent. From the results obtained, the value of [α]D²⁰+48.3°, which has been reported by NAVES was found to be a reliable one of 4S-(+)-terpinen-4-ol. Furthermore, some monoterpenes such as a-thujene, sabinene and sabinene hydrate are known to be very sensitive to acid and rearrange to terpinen-4-ol accompanied by partial racemization. Therefore, the low optical rotations given for terpinen-4-ol isolated from various essential oils by previous workers, seem to be caused by isomerization of terpenes which are labile to acid, during the isolation of this alcohol.","subitem_description_type":"Other"}]},"item_20004_description_20":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_20004_description_21":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_20004_description_22":{"attribute_name":"その他の資源識別子","attribute_value_mlt":[{"subitem_description":"信州大学農学部紀要 14(1): 119-125(1977)","subitem_description_type":"Other"}]},"item_20004_full_name_16":{"attribute_name":"公開者(その他言語)","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"信州大学農学部"}]}]},"item_20004_identifier_23":{"attribute_name":"資源識別子URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/10091/2313"}]},"item_20004_source_id_25":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0583-0621","subitem_source_identifier_type":"ISSN"}]},"item_20004_source_id_26":{"attribute_name":"処理レコードID(総合目録DB)","attribute_value_mlt":[{"subitem_source_identifier":"AN00121352","subitem_source_identifier_type":"NCID"}]},"item_20004_version_type_51":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"url":{"url":"https://soar-ir.repo.nii.ac.jp/?action=repository_action_common_download&item_id=10801&item_no=1&attribute_id=65&file_no=1"}}]},"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":"Terpinen-4-olの光学活性について(不斉シフト試薬を用いた核磁気共鳴による光学純度の測定)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Terpinen-4-olの光学活性について(不斉シフト試薬を用いた核磁気共鳴による光学純度の測定)"}]},"item_type_id":"20004","owner":"3","path":["2668"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-09-02"},"publish_date":"2020-09-02","publish_status":"0","recid":"33155","relation_version_is_last":true,"title":["Terpinen-4-olの光学活性について(不斉シフト試薬を用いた核磁気共鳴による光学純度の測定)"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-15T20:38:39.987830+00:00"}
