Abstract

The invention discloses a preparation method for active pure sea-buckthorn powder tablets. The preparation method comprises the following steps that 1, fresh harvested sea-buckthorn is washed with water and drained; 2, the pretreated sea-buckthorn is squeezed, and sea-buckthorn juice and sea-buckthorn residues are collected respectively; 3, the sea-buckthorn juice is subjected to vacuum concentration to obtain clear paste with a certain relative density; 4, the sea-buckthorn residues are placed in a drying bin for vacuum freeze drying, and after drying and pressure release, the sea-buckthorn residues are taken out of the drying bin; 5, the dried sea-buckthorn residues are smashed with an air jet pulverizer; 6, the sea-buckthorn juice clear paste and the sea-buckthorn residue powder are mixed, pelletized, dried, rounded and tabletted, and then the active pure sea-buckthorn powder tablets are obtained. By means of the method, the freeze-drying time is shortened, the freeze-drying energyconsumption is reduced, the unit yield is improved, active and effective ingredients are reserved, and the high rehydration capability of the product is maintained.

Description

technical field [0001] The invention relates to a drying method of seabuckthorn, in particular to a preparation method of active seabuckthorn pure powder. Background technique [0002] Seabuckthorn, a shrub, small tree or tree of the genus Seabuckthorn in the family Echinacea, is produced in Europe and Asia. In 1977, seabuckthorn, as one of the natural medicinal and edible plants, was recorded in the "Chinese Pharmacopoeia" for the first time. Seabuckthorn contains flavonoids, proanthocyanidins, vitamins and other nutrients, and is widely used in food, medicine, cosmetics and other fields. In recent years, studies have found that the main active ingredients in seabuckthorn are flavonoids. Flavonoids are a class of important biologically active substances that can significantly increase coronary blood flow, increase myocardial nutritional blood flow, reduce myocardial oxygen consumption, and inhibit platelets. Aggregation can significantly improve arrhythmia, hyperlipidemia...
