Abstract
【解決手段】 ユーグレナをプリン体吸収抑制のための有効成分とする。これにより、食事により腸管から吸収されようとしているプリン体の吸収を抑制し、体外へ排出させることができる。また、ユーグレナを血中尿酸値低減のための有効成分とする。これにより、ユーグレナを経口的に摂取することにより、尿酸の血中滞留量を低減し、痛風の原因となる尿酸値を低減することができる。本発明においては、該血中尿酸値低減剤を、飲食用組成物に含有させて利用することが好ましい。
【選択図】なし
Description
Cramer-Myers培地(Arch,Mikrobiol.,17,384-402(1952))、Hutner培地(J.Protozool.,14,Suppl.,p17(1967))、Koren-Hutner 培地(J.Protozool.,6,p23(1959))などが挙げられる。ユーグレナの培養は、静置培養、振盪培養、通気攪拌培養などにより行なわれる。また、屋外プールなどに水深20センチ程度のミネラル含有培地をはり、攪拌装置を移動させて攪拌しながら太陽光に曝し、光合成によるCO2固定により、光をエネルギー源としCO2を炭素源として利用して、エネルギー・培地の利用効率的よく培養することができる。
ユーグレナのプリン体吸着能を調べた。
<HPLC測定条件>
・試料注入量 10μL
・カラム Hydrosphere C18 4.6×150mm(D) (5μm)
・流速 0.7mL/min
・波長 254nm
・カラム温度 37℃
・移動相 50mM Na2HPO4-H3PO4(pH3.0)
各種素材による吸着能は、アデノシンあるいは5'-AMPの添加量と、HPLCデータに基づいて算出した全溶液中に含まれる量との差分が、各種素材に吸着した量であるとして、下記式(1)により求めた。
20歳以上、65歳未満の健常男子、もしくは試験責任医師が高尿酸血症予備群(境界域)と判断した者で、負荷試験実施2日前から禁酒が可能な4人の被験者を選び、ユーグレナ摂取による血中尿酸値低減の効果について、試験を行った。
<製造例1>
上記ユーグレナ乾燥粉末を、プルラン製ハードカプセル(日本薬局方1号サイズ)に1カプセル当たり334mgずつ充填し、ハードカプセル剤を得た。
