Description
北海道産カラマツ(学名Larix leprolepis Gordon)の粉砕物10g(粒径1cm以下)を、0.025、0.05、0.1、0.25mol/lの水酸化ナトリウム溶液またはアンモニア水90mlを用いて、常温、1時間の条件で処理した。得られた抽出溶液を凍結乾燥して固形物とした。この固形物の重量を測定した。結果を表1に示す。
北海道産トドマツ(Abies Sachalinemsis Fr Schm)、エゾマツ(Picea jezoensis Carr.)の混合粉砕物10g(粒径0.1cm以下)を0.025、0.05、0.1、0.25mol/lの水酸化ナトリウム溶液90mlを用いて、常温、1時間の条件で処理した。得られた抽出溶液を凍結乾燥して固形物とした。この固形物の重量を測定した。結果を表1に示す。
ロシア産カラマツ(学名Larix gmelinii Gordon)の粉砕物10g(粒径1cm以下)を0.025、0.05、0.1、0.25mol/lの水酸化ナトリウム溶液90mlを用いて常温、1時間の条件で処理した。得られた抽出溶液を凍結乾燥して固形物とした。この固形物の重量を測定した。結果を表1に示す。
北海道産ミズナラ(学名Quercus mongolica v.grosseserrats) の粉砕物10g(粒径1cm以下)を0.1mol/lの水酸化ナトリウム溶液90mlを用いて常温、1時間の条件で処理した。得られた抽出溶液を凍結乾燥して固形物とした。この固形物の重量を測定した。結果を表1に示す。
カラマツおがくず100gを70℃の脱イオン水900mlで2時間処理した後、濾紙(5C)を用いて濾過し、カラマツおがくずを回収した。この工程を合計3回繰り返して行い、不要な成分であるアラビノガラクタンを、カラマツおがくずから除去した。
実施例1〜5において得られた固形物10mgを10リットルのテドラーバッグに入れた。40〜50ppmのホルムアルデヒドを含有する空気10リットルを導入して、24時間後のホルムアルデヒド除去率を測定した。結果を表1に示す。ホルムアルデヒドの濃度測定にはADVANTEC製ホルムアルデヒド用検知管91および91Lを使用した。
市販されているリグニン(関東化学株式会社製、カタログ番号;24104−32(以下、単に試薬リグニンとも称する。))100mgを10リットルのテドラーバッグに入れた。40〜50ppmのホルムアルデヒドを含有する空気10リットルを導入し、24時間後のホルムアルデヒド除去率を測定した。結果を表1に示す。ホルムアルデヒドの濃度測定には、ADVANTEC製ホルムアルデヒド用検知管91および91Lを使用した。
市販されている活性炭(味の素ファインテクノ製CL−H)10mgを10リットルのテドラーバッグに入れた。40〜50ppmのホルムアルデヒドを含有する空気10リットルを導入し、24時間後のホルムアルデヒド除去率を測定した。結果を表1に示す。ホルムアルデヒドの濃度測定にはADVANTEC製ホルムアルデヒド用検知管91および91Lを使用した。
カラムは、昭和電工株式会社製GPCカラム;ShodexKS802及びKS804を直列にして使用した。カラム温度は40℃とし、溶離液として超純水(流量0.6ml/min)を使用した。検出器は(RI)を使用した。また、分子量180、1810、5900、12200、22800、47300のプルランで検量線を作成した。結果を図1に示す。
