Abstract

(CZ) is a perennial herb belonging to the family. CZ is used medicinally to treat inflammatory and uterine diseases in Asia. CZ was extracted with 50% ethanol and CZ extract (CZE; at 125, 250, and 500 mg/kg body weight) was administered orally every day for 5 or 6 weeks to investigate the anti-diabetic effects in streptozotocin (STZ)-induced rats and STZ + high-fat diet (HFD)-fed mice. CZE significantly decreased fasting blood glucose levels in STZ- and STZ + HFD-induced diabetic models. In addition, glucose tolerance and insulin tolerance were improved in the STZ + HFD + CZE group by increasing insulin levels and decreasing hemoglobin A1c (HbA1c) levels in serum. Furthermore, CZE supplements decreased components of the serum lipid profile such as triglyceride, total cholesterol, and low-density lipoprotein cholesterol levels. These results suggest that CZE may be a potential candidate for controlling hyperglycemia.

摘要

(CZ)是一种属于该科的多年生草本植物。在亚洲,CZ被用于药用治疗炎症和子宫疾病。用50%乙醇提取CZ,并将CZ提取物(CZE;体重分别为125、250和500毫克/千克)每天口服给药5或6周,以研究其对链脲佐菌素(STZ)诱导的大鼠和STZ+高脂饮食(HFD)喂养的小鼠的抗糖尿病作用。CZE显著降低了STZ和STZ+HFD诱导的糖尿病模型的空腹血糖水平。此外,通过提高胰岛素水平和降低血清中糖化血红蛋白(HbA1c)水平,STZ+HFD+CZE组的葡萄糖耐量和胰岛素耐量得到改善。此外,CZE补充剂降低了血清脂质谱的成分,如甘油三酯、总胆固醇和低密度脂蛋白胆固醇水平。这些结果表明,CZE可能是控制高血糖的潜在候选药物。
