Ultrahigh-pressure preparation method of freeze-dried cistanche decoction pieces and cistanche decoction pieces prepared by using ultrahigh-pressure preparation method

Abstract

The invention relates to an ultrahigh-pressure preparation method of freeze-dried cistanche decoction pieces and the cistanche decoction pieces prepared by using the ultrahigh-pressure preparation method. The ultrahigh preparation method comprises the following steps of: washing and slicing cistanche, putting the sliced cistanche into ultrahigh-pressure equipment to carry out high-pressure treatment; putting the decoction pieces subjected to high-pressure treatment into a freeze dryer or low-temperature negative-pressure machine; and filling nitrogen to the dried decoction pieces or carrying out vacuum packaging on the dried decoction pieces. According to the decoction pieces prepared by using the ultrahigh-pressure preparation method, the dissolution rate of active ingredients is high and the extraction time of the active ingredients is short; and all active ingredients of the cistanche can be completely reserved so as to avoid loss and oxidation of the active ingredients, and therefore the decoction pieces can be stored for a long time.

Description

technical field [0001] The invention belongs to the technical field of medicinal plant application research, and in particular relates to a preparation method of superhigh-pressure freeze-dried decoction pieces of Cistanche deserticola. Background technique [0002] Cistanche is the dried fleshy stem with scaly leaves of Cistanche deserticola (Cistanche deserticola Y.C.Ma). Cistanche is a parasitic plant that lives on the roots of desert trees Haloxylon and tamarisk. It is tonic and soothing, and is more suitable for long-term use. And it contains a variety of nutrients, trace elements and vitamins that are useful to the human body. [0003] The amount of Cistanche decoction pieces is increasing year by year, but there are many disadvantages in use, especially in the process of preparing Cistanche decoction pieces. At present, the traditional primary processing methods of Cistanche deserticola include drying, salting, and cellaring. These methods Affected by natural condi...

Problems solved by technology

[0003] The amount of Cistanche decoction pieces is increasing year by year, but there are many disadvantages in use, especially in the process of preparing Cistanche decoction pieces. At present, the traditional primary processing methods of Cistanche deserticola include drying, salting, and cellaring. These methods Affected by natural conditions, the quality is unstable, which seriously affects the utilization rate and curative effect of medicinal materials; moreover, the traditional primary processing method is far from meeting the needs of primary processing of a large number of medicinal materials in the place of origin.

Therefore, how to improve the utilization rate of the rare and endangered medicinal material Roucong Rong, and formulate a method for the initial processing of a large number of medicinal materials in accordance with the origin, so as to ensure the stability and reliability of the quality of medicinal materials, are the key issues to be solved; for example, most of them are used in drying and sterilization. Heat-drying techniques such as microwave or thermal spray make the heat-sensitive ingredients in Cistanche deserticola easily invalid, and the active ingredients are easily destroyed

Moreover, the active ingredients of cistanche decoction pieces prepared in this way are not easy to leach, thereby greatly reducing the efficacy

And the packaging is simple, the raw materials are easily polluted or the active ingredients are easily oxidized and invalidated when exposed to the air for a long time, the quality cannot be controlled, and the dosage cannot be controlled. This is also a great waste of limited Cistanche resources.
