Processing method of Rhizoma Pinellinae Praeparata and Rhizoma Pinellinae Praeparata

Abstract

The invention provides a processing method of Rhizoma Pinellinae Praeparata and Rhizoma Pinellinae Praeparata, belonging to the field of processing of traditional Chinese medicines. The processing method of Rhizoma Pinellinae Praeparata comprises the following steps: putting raw Pinellia tuberifera in a closed vessel, lowering the pressure in the closed vessel to -0.02 to -0.04 MPa; and adding water into the closed vessel until the raw Pinellia tuberifera is immersed in the water, pressurizing the closed vessel to control the pressure in the closed vessel at 0.18-0.30 MPa, soaking the raw Pinellia tuberifera for 4-6 hours, and filtering. The method provided by the invention is capable of greatly shortening the soaking time of Pinellia tuberifera and enhancing the production efficiency, and avoids the loss of effective components in the Pinellia tuberifera and the phenomenon of unqualified ash content and extracts, thereby enhancing the Rhizoma Pinellinae Praeparata decoction piece quality and application safety.

Description

technical field

[0001] The invention relates to the field of processing traditional Chinese medicines, in particular to a method for processing Pinellia fragrans and Pinellia fragrans. Background technique

[0002] Pinellia is the dry tuber of Pinellia araceae. It is excavated in summer and autumn when the stems and leaves are flourishing, and the skin and fibrous roots are removed, and dried or dried, it is the raw pinellia. The dry tubers of Pinellia are spherical, semi-spherical or oblique, with a diameter of 0.6-1.5 cm; there are sunken stem scars at the top, and densely dotted root scars around; the lower part is blunt and smooth. Pinellia pinellia is weak in gas, pungent in taste, numb in the tongue and pungent in the throat; pungent, warm, poisonous, and returns to the spleen, stomach and lung meridians. The main functions and functions are: drying dampness and reducing phlegm, reducing adverse flow and relieving vomiting, dispelling swelling and dissipating stagnati...

Embodiment 1

[0037] The present embodiment provides a kind of processing method of Pinellia fragrans, which comprises:

[0038](1) Take raw pinellia and place it in a closed container, and reduce the pressure in the closed container to -0.03MPa in about 20 minutes; then, add water to submerge the raw pinellia in the closed container, and pressurize the closed container to make the closed container The pressure inside is controlled at -0.25MPa, and then the raw pinellia is soaked for 5 hours, and the mass ratio of water to raw pinellia is 1.7:1, and then filtered.

[0039] (2) Take licorice, add water and decoct twice for 2 hours and 1 hour respectively;

[0040] (3) After soaking and filtering the raw pinellia to remove the filtrate, mix it with solution A, soak it at a pressure of -0.25MPa for 25 hours, filter and dry it to obtain the French pinellia.

Embodiment 2

[0042] The present embodiment provides a kind of processing method of Pinellia fragrans, which comprises:

[0043] (1) Take raw pinellia and place it in a closed container, and reduce the pressure in the closed container to -0.04MPa in about 10 minutes; then, add water to submerge the raw pinellia in the closed container, and pressurize the closed container to make the closed container The pressure inside is controlled at -0.18MPa, and then the raw pinellia is soaked for 6 hours, and the mass ratio of water to raw pinellia is 1.5:1, and then filtered.

[0044] (2) Take licorice, add water and decoct twice for 1.8h and 1.2h respectively, then combine the decoctions obtained from the two decoctions, let cool and add quicklime to obtain solution A.

[0045] (3) After soaking and filtering the raw pinellia to remove the filtrate, mix it with solution A, soak for 30 hours at a pressure of -0.18MPa, filter and dry to obtain Pinellia fragrans.

Embodiment 3

[0047] The present embodiment provides a kind of processing method of Pinellia fragrans, which comprises:

[0048] (1) Take raw pinellia and place it in a closed container, and reduce the pressure in the closed container to -0.02MPa in about 50 minutes; then, add water to submerge the raw pinellia in the closed container, and pressurize the closed container to make the closed container The pressure inside is controlled at -0.3MPa, and then the raw pinellia is soaked for 4 hours, and the mass ratio of water to raw pinellia is 2.0:1, and then filtered.

[0049] (2) Take licorice, add water and decoct twice for 2.2 hours and 0.8 hours respectively, then combine the decoctions obtained from the two decoctions, let cool and add quicklime to obtain solution A.

[0050] (3) After soaking and filtering the raw pinellia to remove the filtrate, mix it with solution A, soak for 30 hours at a pressure of -0.30 MPa, filter and dry to obtain the French pinellia.
