Problems solved by technology

[0005] Schisandra chinensis has been used as a traditional Chinese medicinal material, and the volatile oil in schisandra chinensis has not been extracted separately. If the volatile oil in schisandra chinensis is extracted by traditional methods such as pressing and organic solvent extraction, the total yield of schisandra chinensis oil is about 2-3%, and the purity of schisandra chinensis is low , if the volatile oil of Schisandra chinensis is extracted with an organic solvent, there will be a small amount of organic solvent remaining in the volatile oil

Embodiment 1

[0016] Take Schisandra seeds 100kg and crush them to 60 mesh and put them into CO 2 Supercritical extraction in a 500L extraction kettle, heated for 1 hour, the temperature was controlled at 30°C, CO 2 The flow rate is 2 L / min. Extracted for 4 hours, the pressure was controlled at 200 MPa, and then separated, the primary separation pressure was 100 MPa, the temperature was controlled at 30°C, the secondary separation pressure was 40 MPa, the temperature was 30°C, and the extraction time was 8 hours. The yield is 6%, the B content is 2.30-2.50%, and it is stored in a cold storage at 5 degrees, and the schisandra seed dregs are recycled for making feed.

Embodiment 2

[0018] Get 120kg of schisandra seeds and pulverize them to 60 mesh and put them into CO 2 Supercritical extraction in an 800L extraction kettle, heated for 1 hour, the temperature was controlled at 35°C, CO 2 The flow rate is 2 L / min. Extracted for 6 hours, the pressure was controlled at 240 Mpa, and then separated, the primary separation pressure was 120 MPa, the temperature was controlled at 40°C, the secondary separation pressure was 45 MPa, the temperature was 40°C, and the extraction time was 8 hours. The yield is 8%, and the B content is 2.30-2.50%. It is stored in a refrigerator at 5 degrees, and the schisandra seed dregs are recycled for making feed.

Embodiment 3

[0020] Get 150kg of schisandra seeds and pulverize them to 60 mesh and put them into CO 2 Supercritical extraction in an 800L extraction kettle, heated for 2 hours, the temperature was controlled at 40°C, CO 2 The flow rate is 2 L / min. Extracted for 7 hours, the pressure was controlled at 260Mpa, and then separated, the primary separation pressure was 150MPa, the temperature was controlled at 50°C, the secondary separation pressure was 60MPa, the temperature was 50°C, and the extraction time was 10 hours.

Abstract

The invention relates to a production method for extracting Chinese magnoliavine fruit volatile oil through CO2 supercritical extraction. The method comprises the following steps: crushing Chinese magnoliavine fruits, putting the crushed fruits in an extraction kettle, controlling the temperature in a range of 30-45DEG C and the CO2 flow at 2L / min, extracting under a pressure of 200-320MPa for 8-15h, carrying out primary separation under 100-200MPa at 30-60DEG C, carrying out secondary separation under 40-70MPa at 30-60DEG C, discharging Chinese magnoliavine fruit oil to obtain the Chinese magnoliavine fruit oil with the yield of 6% and the Schisandrin Bcontent of 2.30-2.50%, preserving in a 5DEG C refrigerator, and recovering Chinese magnoliavine fruit residues to be used for making feeds. The production method has the advantages of simple process and low production cost, and solves the problems of low content and small yield of a Chinese magnoliavine fruit volatile oil pressing method.

Description

technical field [0001] The present invention relates to a kind of preparation method of volatile oil of Schisandra chinensis, especially relates to a method using CO 2 The invention discloses a production method for supercritically extracting volatile oil from schisandra chinensis; the volatile oil from schisandra chinensis is an effective component of Chinese medicinal materials of schisandra chinensis. Background technique [0002] Schisandra ( Schisandra chinensis (Turcz.) Baill.) is an authentic medicinal material in Liaoning, Schisandra chinensis, also known as Northern Schisandra, Liao Schisandra. It is named for its five flavors of sweet, sour, pungent, bitter and salty. It was first recorded in "Shen Nong's Materia Medica" and listed as top grade. "Tu Jing Materia Medica" records: "Schisandra's skin is sweet and sour, the core is hard, and it has a salty taste, so it has five flavors." Hence the name Schisandra. Schisandra Chinese medicinal material, warm in nat...
