Extracts of Scutellaria baicalensis Reduced Body Weight and Blood Triglyceride in db/db Mice

Scutellaria baicalensis has been extensively employed for the clinical treatment of hyperlipidemia, atherosclerosis, hypertension, dysentery, inflammatory diseases, and the common cold. The present study was performed to investigate the anti-obesity and anti-dyslipidemia effect of Scutellaria baicalensis extracts (SBE) in type 2 diabetic db/db mice. Male db/db mice were divided into three groups (n=5) and orally administrated vehicle (control), SBE 10, and 100mg/kg body weight/day for 4weeks everyday. Administration of SBE improves weight gain, hypertriglyceridemia, and hyperinsulinemia in db/db mice. In obese db/db mice, SBE treatment also reduced plasma alanine aminotransferase levels. In the livers of db/db mice, SBE promoted 5' AMP-activated protein kinase activity and restored metabolic process and insulin signaling pathways. Our data demonstrate that SBE exerts potent anti-obesity and anti-hypertriglyceride effects suggesting its useful potential function as adjuvant therapeutic agent for the treatment of weight gain and hypertriglyceridemia.
