Embodiment 1

[0054] The preparation method of silver yellow particles includes the following process steps:

[0055] a. Material preparation

[0056] Picking, cleaning, cutting, and drying honeysuckle and scutellaria;

[0057] b. Preparation of honeysuckle cream

[0058] The honeysuckle treated in step a is decocted with water, the decoction is centrifuged and filtered at high speed, and the filtrate is concentrated under reduced pressure at a low temperature to prepare a honeysuckle clear cream with a relative density of 1.13-1.18 at 70°C;

[0059] c. Preparation of Scutellaria baicalensis Georgi Concentrate

[0060] The scutellaria baicalensis Georgi processed in step a was decocted with 60% ethanol by volume percentage, the decoction was centrifuged and filtered at high speed, and the filtrate was concentrated under low temperature and reduced pressure to produce a scutellaria baicalensis concentrate with a relative density of 1.10 at 60-70°C. Adjust The pH of the concentrated liquid of Scutellar...

Embodiment 2

[0071] The difference between this embodiment and Embodiment 1 is:

[0072] In step b, the speed of the high-speed centrifugation is 13000 rpm and the time is 10 minutes; the temperature of the low-temperature vacuum concentration is 80°C, the pressure is 0.05 MPa, and the time is 24 hours. In step c, the high-speed centrifugal rotation speed is 15000 rpm and the time is 10 minutes; the temperature of low-temperature vacuum concentration is 55° C., the pressure is 0.10 MPa, and the time is 24 hours.

[0073] The process conditions of vacuum drying in step d are: pressure of 0.005 MPa, temperature of 50° C., time of 30 minutes, feed rate of 80 kg / h, and crawler speed of 3 cm / min.

[0074] The rest of the content is the same as in Example 1.

Embodiment 3

[0076] The difference between this embodiment and Embodiment 1 is:

[0077] In step b, the rotation speed of the high-speed centrifugation is 12000 rpm and the time is 15 minutes; the temperature of low-temperature vacuum concentration is 70° C., the pressure is 0.04 MPa, and the time is 36 hours. In step c, the high-speed centrifugal rotation speed is 12,500 rpm and the time is 15 minutes; the temperature of low-temperature vacuum concentration is 53° C., the pressure is 0.07 MPa, and the time is 27 hours.

[0078] The process conditions of vacuum drying in step d are: pressure of 0.003 MPa, temperature of 48° C., time of 45 minutes, feed rate of 75 kg / h, and crawler speed of 7 cm / min.

[0079] The rest of the content is the same as in Example 1.

Abstract

The invention belongs to preparation of Chinese patent medicines and particularly relates to a preparation method of yinhuang particles. The preparation method comprises technological steps as follows: material preparation, preparation of clear paste of honeysuckle flowers, preparation of baical skullcap root concentrate, vacuum drying, granulation and the like. With the adoption of the preparation method, the problems of long preparation cycle, high energy consumption, low efficiency, poor environment-friendliness and complicated granulation process as well as problems that intermediate products are not easy to store and prone to bacterial contamination and the like in the prior art are effectively solved. The method has the advantages of little loss of medicinal composition, short technological process, low preparation cost and low energy consumption; the intermediate products are easy to store and low in bacterial contamination rate.

Description

Technical field [0001] The invention belongs to the preparation of Chinese patent medicines, and particularly refers to a preparation method of silver yellow particles. Background technique [0002] Yinhuang granules are made from the extracts of two Chinese medicines of honeysuckle and scutellaria, which can clear away heat and relieve wind, relieve throat and detoxify. It is used for dry throat, sore throat, swollen larynx nucleus, thirst, fever caused by exogenous wind-heat, lung and stomach heat; acute and chronic tonsillitis, acute and chronic pharyngitis, upper respiratory tract infection, see the above symptoms. The standard for Yinhuang Granules was originally included in the Sixth Volume of the Pharmaceutical Standards of the Ministry of Health (WS 3 -B-1234-92), now included in the 2015 edition of the Chinese Pharmacopoeia. [0003] Yinhuang granules are composed of honeysuckle extract and scutellaria baicalensis extract, so the quality of each extract in the granules wi...
