acid，ならびにセスキテルペンのβ-eudesmolが観測された．これに加え，特徴的な化合物として，スギではkaur-15-ene，sclareol，4-isopropyl-7,11-dimethyl-3,7,11-cyclotetradecatrienone（IDC），ヒノキではhibaene，アカマツではborneol及び(13R)-8,13-epoxy-labd-14-eneが特異的にみられた．広葉樹のクリの花粉からは，benzyl alcohol，phenylethyl alcohol（PEA），tetracosaneが特徴的な物質として挙げられた．林から採取した各針葉樹花粉の化学物質も市販品と同様であり，これらの物質が花粉マーカーの候補になり得ることが確認された．次に，花粉飛散の季節に，大気に浮遊する花粉をフィルターに採取し，捕集物をフィルターごと加熱脱着に供して分析したところ，スギ花粉由来と思われるIDCやクリ花粉に含まれるPEAが検出された．また，IDCやPEAの大気中における濃度の推移を調べると，それぞれスギやクリの花粉の飛散状況に応じて増減していることが確認された．今後，さらに網羅的かつ詳細なデータの蓄積や花粉の捕集脱着自動分析装置の開発によって，飛散花粉の種類や量について化学的な観測が可能になると期待される．","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"en","subitem_1522300316516":"（公社）日本分析化学会"},{"subitem_1522300295150":"en","subitem_1522300316516":"The
