Description
−キサントフィル(1種類または2種類以上)をエステル化された形で含有するマリーゴールド花の抽出物を用意し
−マリーゴールド花抽出物を鹸化し,そして
−キサントフィルを単離する,
の各工程を含み,マリーゴールド花抽出物を鹸化する工程を4級アンモニウム塩基の存在下で行うことを特徴とする。
R2,R3,R4は,互いに独立して,1−6個のC原子を有するアルキルである]
を含む。
−鹸化混合物を水で希釈し,
−希釈した混合物を濾過し,
−固体残渣を単離し,洗浄し,乾燥する。
マリーゴールド花からキサントフィルをエステル化された形で抽出するためには,慣用の溶媒,例えば,ヘキサンまたは石油エーテルを用いる。溶媒の量はマリーゴールド花の重量の8倍であることができる。抽出は,60℃+/−2℃で2回行う。合わせた抽出溶液を70℃+/−3℃で減圧下で濃縮する。溶媒を回収した後,濃縮された抽出物を得る。UV分析によれば,濃縮ペースト中のルテインジエステルの量は,約15%である。
工程1で得られた濃縮ペーストを以下の条件を用いて鹸化する:
濃縮ペーストと鹸化剤(NaOH)および溶媒(エタノール)との比率は,約50/35/250(濃縮ペースト/NaOH/エタノール)である。
鹸化方法は,75℃+/−3℃で約3時間撹拌することにより行う。
鹸化反応の完了後,15倍(濃縮したペーストの重量と比較して)の80℃の熱水を反応混合物に加える。溶液を約3分間撹拌した後,濾過する。好ましくは,迅速に濾過するためにより大きな直径のフィルターを用いる。
