タモギタケから単離したエルゴチオネインの生体内抗酸化性に関する研究 A Study of In vivo Antioxidative Activity of Ergothioneine Isolated from the Pleurotus Cornucopiae var. Citrinopileatus. 福田, 絵里 山岸 和敏 知地 英征 FUKUDA, Eri YAMAGISHI Kazutoshi CHIJI Hideyuki We investigated the serum antioxidative activity in the hepatic portal vein at 5, 15, 30, 60, and 90 minutes after the injection of 0.1% ergothioneine into the small intestine of rats using Oxygen Radical Absorbance Capacity (ORAC). Furthermore, we attempted to identify ergothioneine in the rat serum by electric spray ionization liquid chromatography mass spectrometry (ESI-LC-MS). No changes were observed in the ORAC values from the hepatic portal vein of rats administered and those not administered ergothioneine. Further, no molecular ion peaks were observed in the rat serum by the ESI-LC-MS. 9 KJ00008510347 2013-03-31 jpn departmental bulletin paper https://fujijoshi.repo.nii.ac.jp/records/818 AA12605795 50 59 63 https://fujijoshi.repo.nii.ac.jp/record/818/files/KJ00008510347.pdf application/pdf 317.6 kB 2016-08-22
