Saure Carhoxypeptidase, welche Phenylalanin von CbO-Leu-Phe-OH bei pH 5,3 abspaltet, ist ein in höheren Angiospermen weit verbreitetes Enzym. Es scheint dagegen in primitiven Angiospermen (Fagus und Magnolia) sowie in Gymnospermen und Kryptogamen (Ausnahme: Equisetum) zu fehlen. Bei Zitrone ist die Aktivität saurer Carboxypeptidase von Natur und Alter der extrahierten Gewebe abhängig (Exocarp u...

PURPOSE To evaluate the acute hepatotoxicity of Equisentum arvense L. in rats. METHODS Fifty Wistar rats were used, these being divided in four groups, one being the control (receiving only water) and the other groups receiving graded doses of Equisentum arvense L. (30, 50, and 100mg/kg respectively) for 14 days. Blood samples were obtained to determine TGO, TGP, FA, DHL and GT-gamma activiti...

The petroleum ether (PE), chloroform (CH), ethanol (ETH) and water extracts of E. arvense stems were evaluated for anti-anxiety activity in mice using elevated plus maze model. Ketamine induced hypnosis and actophotometer was used to evaluate sedative effect with various extracts in mice. The results were compared with standard drug diazepam. The ethanolic extract of E. arvense (50 and 100 mg/k...

The hypoglycemic effect of water as well as butanolic extracts prepared from aerial parts of Equisetum myriochaetum (Equisetaceae) was examined in streptozotocin induced diabetic rats. A single oral administration of the water extract (WE) at doses of 7 and 13 mg/kg and of the butanol extract (BE) at doses of 8 and 16 mg/kg significantly (P<0.001) lowered the plasma glucose levels in diabetic r...
