Abstract

The invention discloses a method for extracting vitamin C from ephedra fruits. The ephedra fruit vitamin C is prepared from ephedra fruits through the steps of colloid mill grinding, compound enzyme enzymolysis, ultrasonic extraction, a CO2 extraction method, filtration membrane and polyamide column purification and the like. By virtue of the extraction method, vitamin C of the ephedra fruits can be effectively preserved, and the extraction rate and efficiency of the ephedra fruits are improved, so that the application and development of the ephedra fruits are promoted to a certain degree.

Description

technical field [0001] The invention relates to a method for extracting vitamin C from ephedra fruit, belonging to the technical field of plant extraction. Background technique [0002] Ephedra, also known as ephedra grass, grass ephedra, middle ephedra, horsetail ephedra, is a perennial herb plant, mainly distributed in the Gobi desert in my country, generally natural and wild, with a wide area distribution, it is a precious traditional Chinese medicine. Ephedra is mild in nature, has the effects of relieving exterior and expelling wind, regulating blood and analgesia, dissipating heat and relieving throat, and raising blood pressure. It is a good medicine for treating colds, coughs, pneumonia, bronchitis, bronchial asthma, arthritis, and gout. Although the medicinal value and economic value of ephedra are well known, the utilization value of ephedra fruit is seldom known. [0003] The literature [Zhang Jianzhong, Ao Tegen, Su Rina, Preliminary Study on the Nutritional Com...
