Mook-Jung I, Kim H, Fan W, Tezuka Y, Kadota S, Nishijo H, Jung MW: Neuroprotective effects of constituents of the oriental crude drugs, Rhodiola sacra, R. sachalinensis and Tokaku-joki-to, against beta-amyloid toxicity, oxidative stress and apoptosis. Biol Pharm Bull 2002, 25(8).

We tested the constituents of two Rhodiola plants, Rhodiola sacra S. H. Fu and R. sachalinensis A. BOR, and an Oriental crude drug, Tokaku-joki-to, for their neuroprotective effects. Of the 58 compounds tested, six had considerable protective effects against beta-amyloid-induced death of B103 neuronal cells in vitro. These six compounds also showed protective effects against staurosporine-induced cell death, and two of the six compounds protected neurons from H2O2-induced cell death. These results suggest that some of the tested compounds protect neurons from beta-amyloid toxicity based on antiapoptotic and antioxidative activity.
