Embodiment 1

[0044] This embodiment relates to a method for extracting marigold flavonoids, including the following steps:

[0045] 1) Take 50kg of marigold flower meal, add 350L of methanol solution with a concentration of 90%, and extract for 4h by countercurrent extraction at 60°C.

[0046] 2) The extract is concentrated under pressure at a vacuum of 0.07±0.002Mpa and a temperature of 70℃. The concentrated extract is centrifuged and the supernatant is taken. After testing, the solid content in the supernatant is 10 %, at this time, the volume of the concentrated solution is 35L;

[0047] 3) Perform plate and frame filtration on the concentrated liquid, pass the concentrated liquid through a filter cloth with a pore size of 300 mesh, the pressure during the filtration process is 0.5Mpa, collect the clear liquid and the filter cake, and dry the filter cake to obtain a longevity Chrysanthemum flavone.

Embodiment 2

[0049] This embodiment relates to a method for extracting marigold flavonoids, including the following steps:

[0050] 1) Take 50kg of marigold flower meal, add 500L of methanol solution with a concentration of 80%, and extract for 2h by countercurrent extraction at 60°C.

[0051] 2) The extract was concentrated under pressure at a vacuum of 0.07±0.002Mpa and a temperature of 90℃, and concentrated until the concentrated extract was centrifuged and the supernatant was taken. After testing, the solid content in the supernatant 30%, at this time, the volume of the concentrated solution is 40L;

[0052] 3) Perform plate and frame filtration on the concentrated solution, pass the concentrated solution through a filter cloth with a pore size of 500 meshes, and the pressure during the filtration process is 0.3Mpa, and dry the filter cake to obtain marigold flavonoids.

Embodiment 3

[0054] This embodiment relates to the extraction method of water-soluble flavonoids of the present invention, which includes the following steps:

[0055] Take the clear solution obtained in step 3) of Example 1, load the clear solution onto the macroporous resin LX-158, control the flow rate to 1BV / h, analyze the resin with 75% ethanol solution, and concentrate and dry the solution to obtain water-soluble longevity Chrysanthemum polyphenols.

Abstract

The invention relates to a method for industrially extracting marigold flavones. The method comprises the main steps that marigold meal is extracted through a methanol solution, an extracting solutionis concentrated till all the marigold flavones separate out, plate and frame filtering is conducted, thus clear liquid and a filter cake are obtained, the filter cake is dried, and thus the marigoldflavones are obtained, wherein the judgment standard that concentration is conducted till all the marigold flavones separate out is that the content of a solid matter in the clear liquid is 5-30%. Themethod is simple in step, low in cost and suitable for industrial mass production, and the extracted marigold flavones are high in purity, has various biological activity and has high industrial application value.

Description

Technical field [0001] The invention relates to the technical field of extraction of plant functional components, in particular to a method for extracting flavonoids from marigold. Background technique [0002] Marigold is one of the main cultivated herb potted flowers in my country, and it is widely used in indoor and outdoor environment layout. With the development of the nutrition and health industry, the international demand for marigolds is increasing. Marigold not only has ornamental value, but also has good medicinal value. The main components of its pharmacological effect are flavonoids, carotenoids, terpenes, glycosides, essential oils and other ingredients. [0003] Marigold flowers are the main source of lutein. After lutein is extracted, a large amount of marigold residue is discarded as industrial scraps or used as feed. This has a certain impact on the environment, and it also causes a great waste of resources. Studies have reported that marigold flowers are rich i...
