The effects of complex herbal medicine composed of Cornus fructus, Dioscoreae rhizoma, Aurantii fructus, and Mori folium in obese type-2 diabetes mice model

Prediabetes, Diabetes and obesity are the metabolic diseases which are closely linked each other to its properties such as hypertension, hyperlipidemia, and abdominal obesity. Many studies tried to find single therapeutic target for treatment of the metabolic syndrome but failed because of its side effects. Therefore, many investigations focus on the reduction of the blood glucose or the body weight. Glucagon-like peptide-1 (GLP-1), a new therapeutic target for type-2 diabetes which caused by insulin resistance and relative insulin deficiency, is issued nowadays. This study aimed to investigate the antidiabetic effect of a complex herbal medicine, JUL04, composed of Cornus fructus (CF), Dioscoreae rhizome (DR), Aurantii fructus (AF), and Mori folium (MF), on the enteroendocrine L cell and on the obese type-2 diabetes mice. Fully differentiated NCI-H716 cells were treated with each herbal samples and GLP-1 ELISA was performed. The animal model was induced by high fat-and high sucrose-diet with or without JUL04 for 8 weeks, and the body and the epididymal fat weight and the size of white adipocyte were measured. Plasma GLP-1 and insulin concentration were also measured by ELISA. The results of the study demonstrate that JUL04 has anti-diabetes and anti-obesity effects in high fat- and high sucrose-diet induced mice model.
