Embodiment 1

[0018] It is used in the extraction process of active ingredients of Rhizoma Chuanxiong in Yimusheng Chemical Mixture, including:

[0019] (1) Crush Rhizoma Chuanxiong into particles with a particle size of 2-2.5 mm.

[0020] (2) the granules are placed in the soaking container, and the ethanol with a concentration of more than 99% is used to soak for 3 hours, then add distilled water to make the concentration of ethanol reach 78%, and then continue to soak for 18 hours; The temperature is 38-40° C., and stirring is required during the soaking process, and the stirring speed is preferably 20 r / min.

[0021] (3) Obtain the soaking liquid, filter it, recover the ethanol in the soaking liquid in a hot bath, the temperature of the hot bath is 60° C., and obtain the extract after recovering the ethanol.

[0022] (4) The extract is washed with the same volume of distilled water as the extract, filtered, and then the filtrate is concentrated and dried by low-temperature drying techn...

Embodiment 2

[0025] The present embodiment is the comparative example of embodiment 1, and the solution soaked in the present embodiment is different, and concrete setting is as follows:

[0026] (1) Crush Rhizoma Chuanxiong into particles with a particle size of 2-2.5mm.

[0027] (2) The granules are placed in a soaking container, soaked in ethanol with a concentration of 80%, and the soaking time is 20h; the soaking temperature in this step is 38-40°C, and it needs to be stirred during the soaking process. The speed is preferably 20r / min.

[0028] (3) Obtain the soaking liquid, filter it, recover the ethanol in the soaking liquid in a hot bath, the temperature of the hot bath is 60° C., and obtain the extract after recovering the ethanol.

[0029] (4) The extract is washed with the same volume of distilled water as the extract, filtered, and then the filtrate is concentrated and dried by low-temperature drying technology, and the active ingredients of Rhizoma Chuanxiong are obtained aft...

Embodiment 3

[0032] The present embodiment is the comparative example of embodiment 1, and the solution soaked in the present embodiment is different, and concrete setting is as follows:

[0033] (1) Crush Rhizoma Chuanxiong into particles with a particle size of 2-2.5mm.

[0034] (2) The granules are placed in a soaking container, soaked in ethanol with a concentration of 80%, and the soaking time is 40h; the soaking temperature in this step is 20-25°C, and it needs to be stirred during the soaking process. The speed is preferably 20r / min.

[0035] (3) Obtain the soaking liquid, filter it, recover the ethanol in the soaking liquid in a hot bath, the temperature of the hot bath is 60° C., and obtain the extract after recovering the ethanol.

[0036] (4) The extract is washed with the same volume of distilled water as the extract, filtered, and then the filtrate is concentrated and dried by low-temperature drying technology, and the active ingredients of Rhizoma Chuanxiong are obtained aft...

Abstract

The invention discloses a process for extracting a ligusticum wallichii effective component from a motherwort biochemical mixture. The problems of inconsistent extraction effects of the effective components of various medicinal materials and huge waste of the raw materials because different medicinal materials are mixed and extracted by the same extraction method in the prior art are solved. The process comprises the following steps: (1) crushing ligusticum wallichii into granules with the grain size of 1 to 3 mm; (2) putting the granules into a soaking container, soaking with ethanol at the concentration of above 99 percent for 2 to 4 hours, adding distilled water to enable the concentration of the ethanol to be 75 to 80 percent, and continuously soaking for 16 to 20 hours; (3) obtaining a soaking liquid, filtering, recovering the ethanol from the soaking liquid in hot bath, and obtaining an extracting liquid after the ethanol is recovered; (4) washing the extracting liquid with distilled water, filtering, drying and concentrating to obtain the effective component of the ligusticum wallichii. The process has the advantages of high yield, high efficiency, high medicine effect and the like.

Description

technical field [0001] The invention relates to an extraction method, in particular to an extraction process for effective components of Ligusticum chuanxiong in Yimusheng chemical mixture. Background technique [0002] Yimusheng Chemical Mixture is made from more than six kinds of herbs including motherwort, angelica, chuanxiong, peach kernel, paojiang, and licorice (burnt). It has the effects of promoting blood circulation and removing blood stasis, warming meridians and relieving pain. It is mainly used to treat postpartum lochia and abdominal pain due to blood stasis. It is a pale orange-yellow to brown-yellow liquid. The gas is fragrant and the taste is slightly sweet. The Yimusheng chemical mixture is mainly used for livestock such as horses, cattle, sheep and pigs, wherein the dosage for horses and cattle is 200-300mL, and the dosage for sheep and pigs is 30-50mL. [0003] The preparation method of the Yimusheng chemical mixture is disclosed in the prior art. After...
