内容記述 ギンネム(Leucaena leucocephala de Wit)中には,ミモシン(β-〔N-(3-hydroxy pyridone-4)-α-aminopropionic acid)が存在するため, 動物がそれを摂取すると脱毛症, 成長障害, 白内障, 不妊症などを引き起こす。ミモシンの分解産物3-hydroxy-4(IH)-pyridone(DHP)もまた動物に甲状腺腫誘発性があると報告されている。飼料として調製中あるいは調製前にギンネム中のミモシンおよびDHPを不活性化あるいは除去できるのならば,家畜飼料のタンパク源としてギンネムの利用が大きく高揚するだろう。精製ミモシンは蒸留水には難溶性であるが, イオン性溶液には易溶性を示した。ミモシン茎葉部を0∿100%海水あるいは酸類, 塩類の各種濃度液に25℃で24時間浸漬すると, およそ60∿95%のミモシンが溶脱された。ギンネムからのミモシンの溶脱率は試薬の濃度に左右され, 最も効果的なものは0.05N CH_3-COONaで95%ものミモシンが抽出される事がわかった。家畜飼料として利用するのに重要な栄養源である粗脂肪, 粗組織, 粗タンパク質の損失はほとんどなかった。この方法は比較的簡単であり, ミモシンもDHPも同時に除去する事から, 農家における小規模な処理法から, 企業による大規模生産まで応用できる実用的な方法であると思われた。
