Problems solved by technology

The traditional methods of softening Chinese herbal medicines include wetting method, that is, remoistening and moistening of wet materials. However, the traditional softening and cutting process of Chinese herbal medicines takes a long time and is cumbersome. The mastery of Chinese herbal medicines is different, and its processing technology is still stagnant at the level of empirical control, which is extremely unsuitable to the level of modern scientific development. As a result, the loss of active ingredients in Chinese medicinal materials is often quite different, and it is difficult to guarantee the quality and clinical efficacy of its decoction pieces. Among all processed products, the most commonly used form in Chinese medicine is the form of decoction pieces, and various processing forms are carried out on the basis of decoction pieces. The quality of Chinese medicine decoction pieces has a great influence on the quality of each processed product important role

Embodiment 1

[0009] Take 1.0kg of Angelica sinensis, remove impurities and sand, and set aside. After the Angelica sinensis is quickly washed with water, it is neatly packed into a polyethylene bag, 1.5kg of distilled water is added, and the package is decompressed (0.8kpa), vacuum-sealed and ultrasonically softened , Ultrasonic frequency is 60Hz, and ultrasonic temperature is 25℃; after the medicinal materials are softened to no dry or hard cores, take them out and cut them into 1mm thin slices. Dry the cut pieces of traditional Chinese medicine in the shade at room temperature and avoid light.

[0010] Detection of extract content of angelica decoction pieces:

[0011] According to the method of the 2010 edition of the Pharmacopoeia, the hot dip method is used for the determination. In Example 1, 5 sets of parallel tests were performed, and the test results are shown in Table 1.

[0014] The detection result of extract content shows that the stability of the angelica d...

Embodiment 2

[0026] Take 1.5kg of astragalus, remove impurities and sediment, and set aside. After the astragalus is quickly washed with water, it is neatly packed into a polyethylene bag, 2.25kg of distilled water is added, the package is decompressed (0.5kpa), vacuum-sealed, and ultrasonically softened , The ultrasonic frequency is 80Hz, the ultrasonic temperature is 30℃; after the medicinal materials are softened to no dry and hard cores, take them out and cut them into slices of 1.5mm. Dry the cut pieces of traditional Chinese medicine in the shade at room temperature and avoid light.

Embodiment 3

[0028] Take 5.0kg Codonopsis pilosula, remove impurities and silt, and set aside. After astragalus is quickly washed with water, it is neatly packed into a polyethylene bag, and 5.0kg of distilled water is added. The package is vacuum-sealed under reduced pressure (0.6kpa) and ultrasonically softened. , Ultrasonic frequency is 70Hz, and ultrasonic temperature is 35℃; after the medicinal materials are softened to no dry or hard cores, take them out and cut them into 2mm thin slices. Dry the cut pieces of traditional Chinese medicine in the shade at room temperature and avoid light.

Abstract

The invention discloses a novel softening and cutting method in the traditional Chinese medicine preparing process, and relates to the field of traditional Chinese medicine decoction piece preparation. According to the method, a traditional Chinese medicinal material is treated by adopting a vacuum sealed decompression softening method, the osmotic pressure inside the tissue of a traditional Chinese medicinal material can be enhanced, and the affinity between the medicinal material and water is improved; the surface color of a medicinal material softened by the method is darker than that of the original medicinal material, no water-injury or sticky phenomenon occurs, the decoction pieces have high softening speed, good effect, appropriate softness and no white or hard core in the section, and the aim that water is used up when a medicine is infiltrated can be achieved. The decoction pieces are convenient to cut, process parameters, such as water addition, moistening time and the like, in the softening step can be easily controlled, and water-soluble ingredients cannot be easily lost.

Description

Technical field [0001] The invention relates to the field of processing Chinese medicinal pieces, in particular to a new method for softening and cutting Chinese medicinal materials during processing. Background technique [0002] The softening and cutting of Chinese medicinal materials is an extremely critical link in the processing of decoction pieces. Improper softening can cause medicinal materials to "damage water" or "hard heart". If the medicinal material is too soft, the slice shape will be poor, and the water-soluble ingredients will easily be lost or spilled on the surface of the medicinal material; the medicinal material is not softened enough, causing too much debris in the cutting process, causing waste of medicine resources and affecting the dissolution of the effective ingredients of the medicine Wait. The processing of Chinese medicinal materials directly affects the quality of decoction pieces, and the quality of decoction pieces will affect the effectiveness a...
