LEE) together with seven known tannins. Rubusuaviin A was characterized as 1-O-galloyl-2,3-O-(S)-HHDP-4,6-O-(S)-sanguisorboyl-β-D-glucopyranose. Rubusuaviins B, C, and E are dimeric, trimeric, and tetrameric ellagitannins, respectively, in which the sanguisorboyl groups were connected ellagitannin units. Rubusuaviins D and F were desgalloyl derivatives of rubusuaviins C and E, respectively. The inhibition of α-amylase activity by rubusuaviins and related ellagitannins was compared. Ellagitannins with β-galloyl groups at the glucose C-1 positions showed stronger inhibition compared with the α-galloyl and desgalloyl compounds. The molecular weight of these compounds was not important for the inhibition of α-amylase activity.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Chemical & Pharmaceutical Bulletin v.55(9) p.1325-1331, 2007","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Pharmaceutical Society of Japan"}]},"item_2_relation_11":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"17827756","subitem_relation_type_select":"PMID"}}]},"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/cpb.55.1325","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/cpb.55.1325"}]}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10885497","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00092363","subitem_source_identifier_type":"ISSN"}]},"item_2_source_id_8":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"1347-5223","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":"Li, Haizhou"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tanaka, Takashi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Zhang, Ying-Jun"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yang, Chong-Ren"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kouno, Isao"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-23"}],"displaytype":"detail","filename":"CPBul55_1325.pdf","filesize":[{"value":"306.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"CPBul55_1325.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/21025/files/CPBul55_1325.pdf"},"version_id":"2bcc4255-00dd-4f2a-9f9a-41cd51fb0699"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Rubus suavissimus","subitem_subject_scheme":"Other"},{"subitem_subject":"Rosaceae","subitem_subject_scheme":"Other"},{"subitem_subject":"ellagitannin","subitem_subject_scheme":"Other"},{"subitem_subject":"amylase","subitem_subject_scheme":"Other"},{"subitem_subject":"polyphenol","subitem_subject_scheme":"Other"},{"subitem_subject":"tannin","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":"Rubusuaviins A-F, Monomeric and Oligomeric Ellagitannins from Chinese Sweet Tea and Their α-Amylase Inhibitory Activity","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Rubusuaviins A-F, Monomeric and Oligomeric Ellagitannins from Chinese Sweet Tea and Their α-Amylase Inhibitory Activity"}]},"item_type_id":"2","owner":"2","path":["74"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-03-04"},"publish_date":"2008-03-04","publish_status":"0","recid":"21025","relation_version_is_last":true,"title":["Rubusuaviins A-F, Monomeric and Oligomeric Ellagitannins from Chinese Sweet Tea and Their α-Amylase Inhibitory Activity"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T02:12:41.363504+00:00"}
