  Hepatoprotective triterpenes from traditional Tibetan medicine Potentilla anserina

  摘要：

  A methanol extract from the tuberous roots of Potentilla anserina (Rosaceae) exhibited hepatoprotective effects against D-galactosamine (D-GalN)/lipopolysaccharide-induced liver injuries in mice. Six triterpene 28-O-monoglucopyranosyl esters, potentillanosides A-F, were isolated from the extract along with 32 known compounds, including 15 triterpenes. The structures of potentillanosides A-F were determined on the basis of spectroscopic properties and chemical evidence. Four ursane-type triterpene 28-O-monoglycosyl esters, potentillanoside A (IC50 = 46.7 mu M), 28-O-beta-D-glucopyranosyl pomolic acid (IC50 = 9.5 - mu M), rosamutin (IC50 = 35.5 mu M), and kaji-ichigoside F1 (IC50 = 14.1 mu M), inhibited D-GalN-induced cytotoxicity in primary cultured mouse hepatocytes. Among these four triterpenes, potentillanoside A, rosamutin, and kaji-ichigoside F1 exhibited in vivo hepatoprotective effects at doses of 50-100 mg/kg, p.o. The mode of action was ascribable to the reduction in cytotoxicity caused by D-GalN. (C) 2014 Elsevier Ltd. All rights reserved.
