- Tsujita T, Takaku T. Lipolysis induced by segment wall extract from Satsuma mandarin orange (Citrus unshu Mark). J Nutr Sci Vitaminol (Tokyo). 2007;53:547-51 pubmed..These results suggest that the segment wall, an edible fraction, from Satsuma mandarin orange might be useful as a functional food, especially as a fat-reducing material...
- Tsujita T, Takaku T, Suzuki T. Chestnut astringent skin extract, an alpha-amylase inhibitor, retards carbohydrate absorption in rats and humans. J Nutr Sci Vitaminol (Tokyo). 2008;54:82-8 pubmed..These results suggest that CAS extract retards absorption of carbohydrate and reduces post-prandial hyperglycemia. ..
- Tsujita T, Takaku T. Mechanism of the inhibitory action of chestnut astringent skin extract on carbohydrate absorption. J Nutr Sci Vitaminol (Tokyo). 2008;54:416-21 pubmed..CAS extract prevented increases in body weight and fasting blood glucose concentration. These data suggest that CAS extract has an anti-diabetic function in type 2 diabetic mice that mainly functions through inhibition of alpha-amylase. ..
