Embodiment 1
[0020] (1) Preparation of lutein: 800 g of marigold flower granules, crushed to a particle size of 20 mesh, supercritical CO 2 The extraction conditions are: extraction pressure is 30MPa, extraction temperature is 45°C, CO 2 The flow rate is 60L / h, and the amount of entrainer ethanol is 20% of the raw material; supercritical CO 2 The separation conditions are as follows: the pressure of the primary separation tank is 8 MPa, and the temperature is 45°C; the pressure of the secondary separation tank is 5 MPa, and the temperature is 45°C. After dynamic operation for 4 hours, the extract was obtained from the primary separation kettle, and after standing, filtering and concentrating, 76 g of lutein oleoresin was obtained, with a lutein content of 6.0%;
[0021] (2) Preparation of α-linolenic acid: take perilla seed and refine it after pressing (commonly used refining method in production) to obtain α-linolenic acid, wherein the content of α-linolenic acid in perilla seed oil is 4...
Embodiment 2
[0025] 800g of marigold flower granules, and 20g of perilla seeds rich in α-linolenic acid are added to it at the same time, the crushed particle size is 20 mesh, supercritical CO 2 The extraction conditions are: extraction pressure is 30MPa, extraction temperature is 45°C, CO 2 The flow rate is 50L / h, and the amount of entrainer is 20% of the raw material; supercritical CO 2 The separation conditions are as follows: the pressure of the primary separation tank is 8 MPa, and the temperature is 45°C; the pressure of the secondary separation tank is 6 MPa, and the temperature is 45°C. The dynamic operation is 4 hours, the extract is obtained from the primary separation tank, and after standing, filtering and concentrating, 78g of perilla seed oil and lutein oleoresin mixture (including 6g of perilla seed oil) is obtained, and the lutein content is 5.6%; Same as implementation example 1. The prepared compound soft capsules are 500 mg each, and the formula is: 6 mg of lutein, 200...
Embodiment 3
[0027] Marigold flower granules 1000g, crushed particle size is 20 mesh, supercritical CO 2 The extraction conditions are: extraction pressure is 30MPa, extraction temperature is 45°C, CO 2 The flow rate is 60L / h, and the amount of entrainer is 20% of the raw material; supercritical CO 2 The separation conditions are as follows: the pressure of the primary separation tank is 8 MPa, and the temperature is 45°C; the pressure of the secondary separation tank is 5 MPa, and the temperature is 45°C. After dynamic operation for 5 hours, the extract was obtained from the first-stage separation tank, and after standing, filtering and concentrating, 92 g of lutein oleoresin was obtained, and the lutein content was 6.3%; the others were the same as in Example 1. The prepared compound soft capsules are 750 mg each, and the formula is: 9 mg of lutein, 300 mg of α-linolenic acid, 1 mg of vitamin A, and 2 mg of vitamin E.
