Embodiment Construction

[0019] It will be described in detail below in conjunction with the accompanying drawings. attached figure 1 For technical process, the okra pectin polysaccharide preparation method process flow chart of the present invention is as follows:

[0020] (1) Preparation of okra powder: select fresh green okra pods, wash with tap water, cut off the stalks, dry in an oven at 60° C., crush and pass through 40 meshes.

[0021] (2) Extraction of okra pectin polysaccharide: Take a certain amount of okra powder, add distilled water according to the ratio of solid to liquid of 1:25, and adjust the extract to pH 1 with sulfuric acid, place it in a 40Khz ultrasonic wave at 25°C for 10 minutes, Then extract at a temperature of 70°C for 3h, and then centrifuge the polysaccharide extract at 5000 Or / min for 10min.

[0022] (3) Separation of the crude polysaccharide of okra: the polysaccharide extract is concentrated on a rotary evaporator, and after being concentrated to 1 / 5 of the volume, abs...

Abstract

The invention discloses a preparation method of okra pectic polysaccharides with high cholesterol removal activity. The method comprises the following steps: preparing okra powder, extracting okra pectic polysaccharides, separating crude okra polysaccharides, purifying the okra pectic polysaccharides, carrying out reduced pressure concentration on obtained extract liquid, carrying out alcohol precipitation, removing proteins, and carrying out freeze drying to obtain the okra pectic polysaccharides. The okra pectic polysaccharides obtained through the method have certain anti-oxidation activity, and also have high cholesterol removal ability.

Description

technical field [0001] The invention specifically relates to an okra pectin polysaccharide with high cholesterol-scavenging activity and a preparation method thereof, belonging to the technical field of biological health care products. Background technique [0002] Okra (Abelmoschus esculeutus Linn.), also known as okra, okra, coffee ambrette, etc., is an annual herb of the genus Okra in the Malvaceae family. [0003] Okra fruit is rich in nutrients and contains flavonoids, polysaccharides, amino acids, fatty acids, minerals, etc. It has many health functions such as anti-fatigue, anti-cancer, lowering blood fat, improving body immunity, strengthening kidney and tonifying deficiency, etc., especially for male organic diseases. It can be used as a nutritious vegetable and as a medicine. Use health supplements. Europe and the United States and other countries have included it in the list of the best green foods in the 21st century. The Japanese call it "green ginseng", and ...
