Problems solved by technology

In this method, adding dextrin before spray drying will increase the humidity, which will cause agglomeration, and will cause the spray-dried powder content to be unqualified. In addition, this method does not realize the benefits of concentrating fresh motherwort juice within a certain range, and does not Aware of the need for drying, sieving, sizing steps after granulation
[0005] At the same time, the above two methods did not take into account the low content of active ingredients in wild fresh motherwort, which is uncontrollable, and did not take into account the use of modern agricultural technology to cultivate fresh motherwort with high yield, high efficiency and high biological activity.
The spray drying uses the principle of instantaneous heating to dry the extract. Although it is instantaneous heating, in the

[0026] Example 1 Preparation of fresh motherwort capsules

[0027] 1. Planting fresh motherwort

[0028] 1.1 Seed selection: select seeds with a purity that does not meet the requirements, use a sieve to screen out debris, eliminate empty, diseased, and other disabled seeds and weed seeds, and select full and full seeds.

[0029] 1.2 Seed treatment: Turn the seeds in the sun for 1 to 2 days before sowing to make the seeds dry uniformly, increase seed permeability and improve viability; at the same time, it also has a certain sterilization effect. Stir 35 kg / mu of plant ash into the seeds before sowing, and then mix them with mature human feces to wet them into seed ash, which is good for controlling the sowing amount.

[0030] 1.3 Site selection and site preparation: Choose sunny, deep soil, rich humus soil and well-drained sandy soil, which is acidic and meets the second-level standards in "National Soil Environmental Quality GB15618-1995", and no single pollutant indicator Exceed t...

Abstract

The invention discloses a method for preparing a fresh traditional Chinese medicine motherwort preparation, comprising the following steps: artificially cultivating motherwort by modern agriculture technologies instead of wild motherwort to obtain fresh high-quality motherwort with less pesticide and heavy metal residuals and high bioactivity; washing the fresh motherwort, sterilizing the fresh motherwort with ozone water, cutting the fresh motherwort into pieces, and homogenizing the motherwort; collecting juice and sieving to obtain fresh motherwort juice; conveying the fresh motherwort juice to a container; decompressing and concentrating the juice at a temperature of 30-80 DEG C to obtain a concentrated solution of which the relative density is 1.01-1.30g/cm<3>; freezing and drying the concentrated solution to obtain fresh motherwort powder; and taking the fresh motherwort powder to prepare into the fresh motherwort preparation. The method provide by the invention is simple in steps and easy to operate; and the prepared fresh motherwort preparation reaches the standard requirements and has good stability. By using the sterilization technology with the ozone water and the freezing and drying process, the microorganism number in the preparation is greatly reduced and the active ingredients of various heat-sensitive activities are retained maximally; and meanwhile, the product yield is improved and the product cost is reduced.

Description

technical field [0001] The invention relates to a preparation method of a traditional Chinese medicine fresh motherwort preparation Background technique [0002] Motherwort is recorded on page 204 of the 2005 edition of the "Chinese Pharmacopoeia", which is the aerial part of the Lamiaceae plant Motherwort. It has the effects of promoting blood circulation and regulating menstruation, diuresis and detumescence. It is used to treat irregular menstruation, dysmenorrhea, amenorrhea, etc. [0003] The main chemical components of Motherwort include alkaloids, diterpenoids, flavonoids, various trace elements and fatty acids. Among them, alkaloids are more researched, which are also important ingredients for the treatment of gynecological diseases, including motherwort and stachydrine hydrochloride. Motherwort raw medicinal materials and motherwort preparations are commonly used clinically, and the quality control is based on stachydrine hydrochloride. "Chinese Pharmacopoeia" 2...
