Abstract

The invention provides an oleanolic acid type saponin compound prepared by arlia elata extraction, separation and purification and having a specific structure. It is found that when the compound is used separately, the compound has remarkable weight-losing and lipid-lowering effects, and the effects are superior to the effect of its aglycone analogue oleanolic acid. When the compound is used withfructo-oligosaccharide, the compound and the fructo-oligosaccharide cooperate with each other and produce a joint action in specific proportion, so that the drug composition has a remarkable weight-losing effect, the weight-losing effect of the composition is superior to the weight-losing effect of a single compound, and the drug composition has a synergistic effect. In addition, the drug composition has the remarkable weight-losing and lipid-lowering effects and has a synergistic effect, the lipid-lowering effect of the drug composition is remarkably superior to the lipid-lowering effect of asingle compound.

Description

technical field [0001] The invention relates to the application of oleanolic acid saponins in the preparation of weight-loss and lipid-lowering medicines, and belongs to the field of medicines or health care products. Background technique [0002] Obesity is a chronic metabolic disease in which excess energy is stored in the body in the form of fat and gradually accumulates to excess due to the body's energy intake exceeding energy consumption. Obesity is a leading cause of death and disease worldwide, and rates have been rising. Obesity increases the risk of metabolic diseases and cardiovascular diseases, and is one of the main causes of cardiovascular diseases. In June 2013, the American Medical Association officially recognized obesity as a disease. Although it is currently possible to reduce the size of the stomach, increase the feeling of fullness, and reduce the amount of food intake through bariatric surgery, so as to achieve the effect of weight loss. But bariatri...
