Description

technical field The invention belongs to the field of chemical synthesis, in particular to a piperazine oleanolic acid salt and a preparation method thereof. Background technique Clinically, oleanolic acid is used for adjuvant treatment of acute and chronic hepatitis. It has a certain protective effect on liver injury, can reduce the elevated serum alanine aminotransferase, promote liver cell regeneration, and accelerate the repair of necrotic tissue. Modern pharmacological studies have shown that oleanolic acid still has the effects of lowering fat, lowering blood sugar, anti-tumor, and two-way regulation of immunity. At present, the development and utilization of oleanolic acid other than liver protection are still rare, and its clinical preparations mainly include tablets and capsules. In terms of physical and chemical properties, oleanolic acid is an alkane-type pentacyclic triterpenoid compound, and its powder is white and crystalline, odorless, tasteless, and insolu...
