Radix isatidis syrup and preparation method thereof

Abstract

The invention relates to the technical field of medicine preparation, in particular to radix isatidis syrup and a preparation method thereof. The preparation method of the radix isatidis syrup comprises the following steps: selecting radix isatidis, using water as a solvent, and extracting the radix isatidis in a circulating way at 65-80 DEG C, collecting extract and concentrating, and carrying out centrifugal filtration to obtain radix isatidis liquid medicine; dissolving sucrose into water for boiling, and mixing the boiled product with the radix isatidis liquid medicine to obtain the radixisatidis syrup. The preparation method provided by the invention extracts the radix isatidis in a circulating way under the low temperature condition, so that the degradation of the extracted components such as polysaccharides and amino acids can be avoided, the content of (R-S)-epigoitrin is increased, and the product effectiveness and the quality stability are improved; furthermore, the concentrated liquid is centrifuged, and the color of the liquid medicine is controlled from the raw materials, so that the clarity of the liquid medicine is improved; the sucrose is processed by using boilingprocess, so that the aromatic degree of the liquid medicine can be improved; the product taste and the consumer experience are improved on the basis of not adding other flavoring auxiliary materials.

Description

technical field

[0001] The invention relates to the technical field of medicine preparation, in particular to a Radix isatidis syrup and a preparation method thereof. Background technique

[0002] Isatis root is the dried root of the cruciferous plant Isatis indigo, which has the effects of clearing heat and detoxifying, cooling blood and reducing swelling. Clinically, it is widely used in the treatment of influenza, mumps, acute and chronic pharyngitis, and herpes simplex keratitis.

[0003] Isatidis preparations include Isatidis Injection, Isatidis Granules, Isatidis Capsules, Isatidis Oral Liquid, Isatidis Syrup, etc.

[0004] At present, the preparation method of Radix Radix Radix Syrup only conforms to the general rules of syrup preparation, and the quality stability and clinical efficacy of the product between batches cannot be guaranteed. Moreover, Radix Radix Radix Syrup has a dark appearance and a fishy smell, which is not suitable for children to take.
