In this present study, phytochemical screening, anti-obesity, anti- antipyretic and analgesic effect of Ephedra alata (EA) extracts were evaluated. Results of this study showed that the methanol EA extract (MEAE) had a stronger inhibition activity on key enzyme related to obesity as lipase (IC50 = 1.296 mg/ml) as compared to water and ethyl acetate extracts ( with IC50 = 1.639 and 1.897 respectively). Also results revealed that ethyl acetate extract depicted high activity toward key enzyme related to hyperglycemia as α-amylase (IC50 = 0.284 mg/mL) while water and methanol extracts showed good to moderate inhibitory activity (IC50 = 1,525 and 1,103 mg/ml respectively). In HFFD rats, the administration of MEAE at 200 mg/kg inhibited key enzyme related to fat digestion and absorption as lipase in the intestine, pancreas and serum by 53, 40 and 53% respectively,which leads to decrease in body weight by 20% and also modulation of lipid profile. In addition, the administration of MEAE to HFFD-rats exerts an inhibitory effect on α-amylase activity in the intestine, pancreas and serum by 43, 26 and 46% respectively and this leads to decrease in blood glucose level by 35%. Also, MEAE exert antipyretic and analgesic activities. This study demonstrates for the first time that MEAE are efficient in preventing obesity and hyperglycemia and liver toxicity. This data generated during study shows antipyretic and analgesic activities of MEAE.
