Embodiment 1

[0068] Example 1: Take the medicinal material of Shichangpu, add 9 times the weight of distilled water to soak for 4 hours, place it in a microwave extractor, set the power of the microwave extractor to 700W, and extract for 90 minutes to obtain Shichangpu volatile oil.

Embodiment 2

[0069] Example 2: Take the medicinal material of Acorus calamus, add 8 times the weight of distilled water and soak it for 6 hours, place it in a microwave extractor, set the power of the microwave extractor to 800W, and extract for 80 minutes to obtain the volatile oil of Acorus calamus.

Embodiment 3

[0070] Example 3: Take the medicinal material of Acorus calamus, add 10 times the weight of distilled water and soak it for 5 hours, place it in a microwave extractor, set the power of the microwave extractor to 600W, and extract for 120 minutes to obtain the volatile oil of Acorus calamus.

[0071] After 90 minutes, the volatile oil of Shichangpu is obtained.

Abstract

The invention discloses a method for extracting rhizoma acori graminei volatile oil by microwaves. The method comprises the following steps of: fetching a rhizoma acori graminei medical material; adding 8-10 weight times of distilled water, and soaking for 3-6 hours; putting in a microwave extractor; and extracting for 80-120min under the power of 600-800W to obtain the rhizoma acori graminei volatile oil. The technical scheme has the biggest characteristics that the extracting speed is high; the time is saved; the solvent consumption is low; and the effective component yield is high. Integrating the factors of all aspects, the technical scheme disclosed by the invention has the remarkable advantage of high extracting efficiency, and is very good in popularization and application prospect.

Description

technical field [0001] The invention relates to the technical field of extraction methods of Acorus calamus, in particular to a method for extracting volatile oil of Acorus calamus with microwaves. Background technique [0002] Calamus ( Acoro tatarinowi Schot) is the dried rhizome of Araceae plant Acorus calamus. The extracted volatile oil contains various chemical components such as volatile oil, sugars, organic acids, amino acids, etc. The main component is asarone, which has the functions of reducing dampness and appetizing, resuscitating phlegm, awakening God puzzle effect. Followed by caryophyllene, shichang ether, asarone, α-slugalene, cis-methyl isobutyl phenol, elemin, dimer-asarone, γ-asarone, d-delta juniperene, Myristic acid, thymol, etc. It is generally believed that the volatile oil of Shichangpu has a two-way regulating effect on the central nervous system, which not only calms the nerves (sedation, anti-convulsion), but also refreshes the brain (excitemen...
