It is remarkable that the maximum yield of GlcNA reached 92 mol% based on D-GlcN. The FT-IR specrum of the isolated D-GlcNA was in fair agreement with the commercial D-GlcNA.","PeriodicalId":170824,"journal":{"name":"Nippon Nogeikagaku Kaishi-journal of The Japan Society for Bioscience Biotechnology and Agrochemistry","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121270308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The principles of this method were based on the light absorbance change through a gelatinized starch-agar gel fixed in a well of a microplate caused by α-amylase action. α-Amylases from different origins were successfully measured. The results of α-amylase activity in enzyme formulations and rice koji extractions measured by this method were in agreement with the values obtained by the conventional method. Since the microplate method is only able to measure α-amylase activity selectively, this method is considered to be extremely practical for quick, multisample treatment.","PeriodicalId":170824,"journal":{"name":"Nippon Nogeikagaku Kaishi-journal of The Japan Society for Bioscience Biotechnology and Agrochemistry","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1999-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130598684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By adding an authentic α-amylase solution to a mixture of agar and gelatinized rice starch, which was fixed in a well of a microplate, the gel turbidity measured at 655 nm was decreased by the α-amylase action on the gelatinized starch. The intensity of the α-amylase-activity was in proportion logarithmically to the turbidity decrease detected by a microplate-reader.

The formation of edema caused in rats paws by injection of carrageenin was effectively depressed by soaking the rat paws in hot oolong tea extract. It gives 60% inhibition at the dose of 75 ppm of oolong tea extract. Oolong tea extract showed higher anti-inflammatory activity than those of green and black tea extracts. The active components were found to be catechins and oolong tea tannin (oxidative products of catechin in oolong tea) fractionated from aqueous oolong tea extract. By oral administration of oolong tea extract, carrageenin-induced inflammation was also inhibited, but the anti-inflammatory avtivity by oral administration was lower than by the soaking treatment. The inflammatory activity of percutaneous absorbed oolong tea polyphenols was assumed to be due, at least partly, to the inhibition of prostaglandin biosynthesis in rat tissue injected with carrageenin.","PeriodicalId":170824,"journal":{"name":"Nippon Nogeikagaku Kaishi-journal of The Japan Society for Bioscience Biotechnology and Agrochemistry","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134203657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
