Abstract

The invention discloses a preparation method for active pure tablets of unibract fritillary bulbs. The preparation method includes the following steps: 1) harvesting the fresh unibract fritillary bulbs, and draining them after washing with clear water; 2) pressing the pretreated unibract fritillary bulbs, and respectively collecting juice and residues of the unibract fritillary bulbs; 3) concentrating the juice of the unibract fritillary bulbs under reduced pressure to obtain clear paste with a certain relative density; 4) putting the residues of the unibract fritillary bulbs into a drying chamber, performing vacuum freeze drying, and taking out the residues from the drying chamber after drying and pressure release; 5) pulverizing the dried residues of the unibract fritillary bulbs by a jet mill; 6) subjecting the clear paste and the powdery residues of the unibract fritillary bulbs to mixing, granulating, drying, sorting and tableting to obtain the active pure tablets of the unibractfritillary bulbs. The preparation method has the advantages that the lyophilization time is effectively shortened, the lyophilization energy consumption is reduced, the unit yield is increased, activeingredients and effective components are maintained, and the good rehydration of the product is retained.

Description

technical field [0001] The present invention relates to a drying method of Fritillariae, in particular to a preparation method of active Fritillaria pure powder tablets. Background technique [0002] Fritillaria is derived from the dried bulbs of various plants of the Liliaceae Liliaceae genus Fritillaria. It has the effects of clearing away heat and moistening the lungs, resolving phlegm and relieving cough, dispersing knots and eliminating carbuncle. It is mainly used to treat lung-heat dry cough, dry cough with less phlegm, yin deficiency and labor cough, and blood in the sputum. Chuan Fritillaria has a long history of medicinal use. It was first recorded in the "Shen Nong's Materia Medica". In high places, the growth cycle is longer. Because of its high development value, the market demand is very large, and the price is also higher than other fritillary. The main active components of Fritillaria are alkaloids, saponins and nucleosides, and there are differences due ...
