Description

technical field [0001] The invention relates to a method for extracting solanesol, in particular to a method for extracting crude solanesol with the aid of microwaves using potato stem and leaf waste as raw materials. Background technique [0002] Solanesol is a long-chain semiterpene alcohol compound and is a synthetic coenzyme Q 10 and vitamin K 2 An important intermediate of coenzyme Q 10 It has the effect of improving myocardial metabolic disorders, and is an essential coenzyme cofactor for energy generation in cells. As an activator of human cell respiration and metabolism and an immune enhancer of the body, it is widely used in the fields of medicine, health care and cosmetics. For example, in the field of medicine, it is used to treat cardiovascular and cerebrovascular diseases, viral hepatitis, duodenal ulcer and cancer patients to reduce the side effects of chemotherapy. The drug is the fifth drug with the largest sales in Japan; 10 It is used to prevent various ...
