For improvement, in Akiyama's method, the extraction solvent and the HPLC column were changed to acetonitrile: 0.1% H3PO4(90+1) and a Capcell Pak C18 (MG 4.6 mm i.d. × 250 mm), respectively. In this improved method, the averaged recoveries from samples spiked with 1, 2 and 5 ng OTA and OTB/g in green coffee, brown rice, wheat and corn were 100.5 and 88.9%, 95.3 and 83.6%, 90.5 and 89.7%, and 96.7 and 101.2%, respectively. The limit of detection was 0.2 ng of OTA and OTB/g in green coffee and cereals. The improved DEA method was applied to the determination of OTA and B in roasted coffee. But concomitant matrices in roasted coffee were not adequately clean‐upped. The limit of detection was only 2 ng of OTA/g.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"本改良DEA固相抽出法は、Akiyamaらの方法から抽出溶媒をアセトニトリル:水:1%リン酸（90+9+1）に、HPLCカラムをカプセルパックC18 MG内径4.6mm×250mm変更した方法であるが、玄米、小麦、トウモロコシ、生コーヒー豆中の0.2ng/gまでのOTAおよびOTBの検出が可能であった。ただし、焙煎コーヒー豆の場合は、2ng/gまでのOTAのみの検出が可能であり、IACを用いた場合より劣っていた。また、本法はクロロホルムなどの毒性の強い有機溶媒を使用せず、コスト面でもIACや多機能カラムより有利であった。操作性の面ではIACより若干劣るが、本法で、一人で1日20検体以上の抽出、クリーンアップ操作が充分可能であった。以上のことから。本法は玄米、小麦、ウモロコシなどの穀物や生コーヒー豆の汚染調査に充分活用しうる方法だと言える。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_heading_23":{"attribute_name":"見出し","attribute_value_mlt":[{"subitem_heading_banner_headline":"応用生物科学科","subitem_heading_headline":"生物資源利用学大講座","subitem_heading_language":"ja"},{"subitem_heading_banner_headline":"Department
