In vitro and in vivo experiments using Achyranthis radix and Drynariae rhizoma extracts were conducted. Antioxidant properties were analyzed and the effects on bone, glucose and lipid metabolism were investigated. Drynariae rhizoma (64.67%) obtained higher DPPH radical scavenging activity compared to Achyranthis radix (19.03%). Similar results were obtained in the reducing power. No differences were observed on the ABTS radical scavenging ability and SOD. In contrast, Achyranthis radix (77.60%) has higher chelating ability compared to Drynariae rhizoma (46.21%). In vivo experiments revealed higher plasma TBARS in OVX-DR than in OVX-AR. Opposite result was seen in erythrocyte TBARS. Hepatic, nephritic and erythrocyte enzymes were considered for the antioxidant enzyme activities. GSH-Px and PON of hepatic enzymes were higher in OVX-AR. While the CAT and GR were higher in OVX-DR. SOD, GSH-Px, GR and PON of nephritic enzymes of OVX-DR were higher compared to OVX-AR. Almost similar values were obtained in CAT using both extracts. The OVX treated rats obtained higher CAT and GR in the erythrocyte enzymes compared to SHAM. The SOD of erythrocyte enzymes in OVX-DR was higher compared to OVX-AR. On the other hand, the GSH-Px was higher in OVX-AR.
