Structural Characterization of Ginseng Adventitious Root Polysaccharides and Their Effects on Ameliorating Insulin Resistance

eFood, Volume 7, Issue 3, June 2026.
Purified ginseng adventitious root polysaccharides (GARP) improve insulin resistance by enhancing glucose and lipid metabolism and reducing oxidative stress. These beneficial effects are mediated, at least in part, through activation of the Nrf2/Keap1 signaling pathway in cellular and animal models.

Purification of Rennet by DEAE-Cellulose Chromatography

Journal of the agricultural chemical society of Japan, 1966
レンネットをDEAE-セルロースカラムに吸着させ, 0.1M燐酸緩衝液(pH 5.7)に0.1, 0.2および0.3M NaClを加えて調製した溶出液および0.1N HClで順次溶出させてレンニンを分離精製し,あわせてレンネット中に混在するペプシンをも分離し,その活性割合を測定した. (1) 0.1M燐酸緩衝液(pH 5.7)に添加するNaClの濃度を0.1Mから0.2Mに増加した溶出液で得られるFraction 3に凝乳力カが存在し, pH 6.62,イオン強度0.2の燐酸緩衝液を用いた電気泳動,沈降分析からみて均一性の高いレンニンが得られた.
