Problems solved by technology

However, microcrystalline cellulose is added in the reprocessing process of this preparation method, which affects the purity of Fritillaria powder, and the material of microcrystalline cellulose is insoluble in water. It is inconvenient to take it; at the same time, the planting process of Fritillaria sichuanensis is not mature enough, and the source is not as extensive as that of Fritillaria taibai; this kind of preparation process takes a long time to process, and the process may cause Fritillaria sichuanensis to be infected by bacteria and microorganisms

Embodiment 1

[0021] A preparation method of Taibai Fritillaria superfine freeze-dried powder, comprising the following steps:

[0022] Step 1: Take an appropriate amount of dried Taibai Fritillaria samples and an appropriate amount of water, put them into an ultrasonic cleaning machine for cleaning and preliminary dispersing and crushing, the ultrasonic processing power is 300W, the intermittent processing is 30min at room temperature, and the ultrasonic processing concentration is 50 %.

[0023] Step 2: Filter the mixed liquid obtained from the ultrasonic treatment in step 1. The filter cake and filter residue are used for mechanical refining. The filtrate is filtered through a sand core funnel to remove water to the remaining volume, and then mechanically processed together with the filter cake and filter residue through a PFI refiner. Refining. After mechanical refining, Taibai Fritillaria pulp was obtained. The refining speed was 1500r / min, the refining gap was 0.2mm, the refining time...

Embodiment 2

[0028] A preparation method of Taibai Fritillaria superfine freeze-dried powder, comprising the following steps:

[0029] Step 1, take the dried Taibai Fritillaria sample for later use, put it into an ultrasonic cleaning machine for cleaning and preliminary dispersion and crushing, the ultrasonic treatment power is 200W, the intermittent treatment is 20min at room temperature, and the ultrasonic treatment concentration is 60%;

[0030] Step 2: Filter the mixed liquid obtained from the ultrasonic treatment in step 1, use the filter cake and filter residue for mechanical refining, filter the filtrate through a sand core funnel to remove water to the remaining volume, and perform mechanical refining together, and obtain Taibai shellfish after mechanical refining For the mother slurry, the mechanical refining equipment is a PFI refiner with a refining speed of 1500r / min, a refining gap of 0.2mm, a refining time of 10min, and a refining temperature of 25±5°C.

[0031] In step 3, th...

Abstract

The invention belongs to the technical field of traditional Chinese medicine powder grinding and preparation, and discloses a preparation method of superfine freeze-dried powder of Fritillaria taibai. The invention uses Fritillaria taibai with mature cultivation technology and high yield as raw material, which is cleaned and pulverized by ultrasonic waves, and mechanically milled. Slurry, centrifugal liquid separation, high-pressure micro-jet homogenization, cold sterilization, and finally freeze-drying or spray-drying, and sieving to obtain the target product Taibai Fritillaria superfine freeze-dried powder. The preparation method of Taibai Fritillaria ultrafine freeze-dried powder of the present invention is helpful to retain various alkaloids in Taibai Fritillaria, the preparation method is simple, time-consuming, suitable for industrial production, and the total alkaloids in Taibai Fritillaria is retained to the greatest extent. Alkaloid components and active components; at the same time, the present invention adopts high-pressure cold sterilization, strong bactericidal power, no loss of drug efficacy, no toxins and unknown substances produced by the drug after sterilization, convenient, economical and effective operation, and the prepared Taibai Fritillaria ultramicro Freeze-dried powder is a nano-level product, which is convenient for its subsequent direct use and further processing.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine powder grinding and preparation, and relates to a preparation method of superfine freeze-dried powder of Taibai Fritillaria. Background technique [0002] Taibai Fritillaria, also known as Taibei, Jianbei, Qinbei, is the dried bulb of Liliaceae. It is mainly used to treat dry cough due to lung heat, dry cough with less phlegm, cough due to yin deficiency, expectoration with blood, 2010 edition 5 Chinese Pharmacopoeia 6-1 Partially loaded under the item of Chuan Fritillaria. Taibai Fritillaria has a long history of medicinal use in Wufeng, Hubei, Wuxi, Chongqing, Jingyuan, Ningxia, and Zhangxian, Gansu, and has been used as a local customary product of Fritillaria sichuanensis. In the local standard of medicinal materials 5 Standards of Chinese Medicinal Materials of Sichuan Province 6 (Supplemented in 1987), 5 Standards of Traditional Chinese Medicinal Materials of Gansu Prov...
