The 80% aqueous acetone extract from the whole plant of Saussurea medusa MAXIM. was found to inhibit rat lens aldose reductase (IC50=1.4 μg/ml). From this extract, flavonoids, lignans, and quinic acid derivatives were isolated together with two new ionone glycosides, saussureosides A and B. Their absolute stereostructures were elucidated on the basis of chemical and physicochemical evidence including the application of modified Mosher's method. In addition, some isolates were found to show an inhibitory effect on aldose reductase. J-Stage>>JOI JST.JSTAGE/cpb/53.1416

武田薬品工業の子会社、和光純薬工業(大阪市)は31日、アルツハイマー病の原因物質とされるたんぱく質「ベータアミロイド42」(A●42)の血液中濃度を測定する試薬キットを開発したと発表した。朝日新聞 2006年05月31日 和光純薬ニュースリリース
15種類の遺伝子情報(DNAマーカー)を調べることにより、国内外で流通、保存されている約70種のイチゴの品種識別ができる技術を、独立行政法人野菜茶業研究所(津市安濃町)が開発した。新品種の識別にも対応でき、同研究所は「品種の偽装表示防止に有効な画期的技術」としている。毎日新聞MSN 2006年5月31日
