Liuwei Dihuang (LWDH) is a famous traditional herbal medicine formula in China that may regulate the balance of kidney yin yang and has been used to restore functional insufficiency of the kidney for a long time in China.
In this study, the water extract of LWDH was tested for its α-Amylase and α-Glucosidase inhibitory activities, and its anti-diabetic property in streptozotocin (STZ)-induced diabetic mice was also analyzed.
LWDH extract inhibited α-Glucosidase and α-Amylase activities in a dose- dependent manner. Treatment of streptozotocin-induced diabetic mice with LWDH extract decreased camp, fasting blood glucose, TC, TG, LDL-c, HbA1C, Urine volume levels and Urine sugar, increased HDL-c level when compared to STZ induced diabetic mice.
This study demonstrates that extract of LWDH can inhibit α-amylase and α-glucosidase activities and shows anti-diabetic effect in a mice preclinical model.
六味地黄丸是中国著名的传统中药配方，可能调节肾阴阳平衡，在中国长期用于恢复肾脏功能不全。
在本研究中，测试了六味地黄丸水提取物的α-淀粉酶和α-葡萄糖苷酶抑制活性，并分析了其在链脲佐菌素（STZ）诱导的糖尿病小鼠中的抗糖尿病特性。
六味地黄丸提取物以剂量依赖性方式抑制α-葡萄糖苷酶和α-淀粉酶活性。与STZ诱导的糖尿病小鼠相比，用六味地黄丸提取物治疗链脲佐菌素诱导的糖尿病小鼠可降低cAMP、空腹血糖、总胆固醇（TC）、甘油三酯（TG）、低密度脂蛋白胆固醇（LDL-c）、糖化血红蛋白（HbA1C）、尿量水平和尿糖，增加高密度脂蛋白胆固醇（HDL-c）水平。
本研究表明，六味地黄丸提取物可抑制α-淀粉酶和α-葡萄糖苷酶活性，并在小鼠临床前模型中显示出抗糖尿病作用。
