Embodiment 1

[0017] Collect fresh maca, wash it, remove the stems and leaves, put the maca root in a vacuum drying room at 0.05Mpa, and dry at 60°C until the moisture content reaches 8%, crush it with a pulverizer and pass through a 20-mesh sieve to obtain dried Maca root powder; powder is placed in a vessel-type extractor using supercritical CO 2 extraction technique, with CO 2 + Entrainer extraction, the entrainer is 95% ethanol, the content is 20% of the total extractant volume content, the extraction pressure is 29.5Mpa, the extraction temperature is 40°C, the extraction time is 4 hours, CO 2 The flow rate is 15kg / kg raw material h, CO 2 It can be re-entered into the extractor for recycling after being separated and frozen, and the obtained ethanol extract is placed in a falling-film vacuum evaporator, and the extract is concentrated and ethanol is recovered at a vacuum degree of 0.82Mpa and a temperature of 43°C, thereby obtaining The concentrated extract of effective ingredients in...

Embodiment 2

[0019] The basic steps of the preparation method are the same as in Example 1, and some parameters and conditions can be changed as follows: Maca root is placed in a vacuum drying chamber and dried at 0.08Mpa and 45°C until the moisture content reaches 7%, and the entrainer during supercritical extraction is 95% ethanol and ethyl acetate are mixed organic solvents according to the volume ratio of 2: 1, and the content is 7% of the total extractant volume content, the extraction pressure is 25Mpa, the extraction temperature is 35 ° C, the extraction time is 2 hours, CO 2 The flow rate is 10kg / kg raw material h, and the obtained organic solvent extract is vacuum-concentrated and recovered at a vacuum degree of 0.7Mpa and a temperature of 57°C; Mix emulsifiers for emulsification, the homogeneous pressure is 25Mpa, the feed temperature during centrifugal spray drying is 82°C, the inlet air temperature is 185°C, and the outlet air temperature is 87°C. The powder obtained after cool...

Embodiment 3

[0021] The basic steps of the preparation method are the same as in Example 1, and some parameters and conditions can be changed as follows: Maca root is placed in a vacuum drying chamber and dried at 0.02Mpa and 60°C until the moisture content reaches 9%, and the entrainer during supercritical extraction is Acetone and normal hexane are mixed organic solvents according to the volume ratio of 3: 1, account for 30% of total extractant volume content, extraction pressure is 32Mpa, extraction temperature is 45 ℃, extraction time is 3 hours, CO 2 The flow rate is 12kg / kg raw material h, and the obtained organic solvent extract is vacuum concentrated and recovered at a vacuum degree of 0.85Mpa and a temperature of 50°C; the concentrated extract is mixed with monoglyceride and maltodextrin in a mass ratio of 1:3 The mixed emulsifier is emulsified, the water concentration of the emulsifier is 2.0%, the weight ratio of the emulsified liquid and the concentrated extract is 1.1: 1, the h...

Abstract

The present invention relates to the field of natural product chemistry and medicine chemistry and provides a method of extracting effective component from plant root and stem. Fresh maka root after being wvacuum drying and ground into powder is supercritical CO2 extracted with CO2 and entrainer to obtain extraction liquid and the extraction liquid is produced into granule through vacuum evaporation to concentrate, mixing with water and emulsifier, homogenization to emulsify and spray to dry. It has high material utilization and effective component extracting rate, and the product has stable pharmacological effect and is easy to dissolve, eat, transport and store.

Description

technical field [0001] The invention belongs to the fields of natural product chemistry and medicinal chemistry, and particularly relates to a method for extracting and concentrating active ingredients from plant rhizomes. Background technique [0002] Maca (Lepidium meyenii walp, commonly known as Maca), a natural medicinal and edible plant, has been cultivated in the Andes of South America for thousands of years, and it is one of the indispensable crops in those areas. Maca root is traditionally used as food and herbal medicine Enhance energy, anti-fatigue, treat women's menopause syndrome, improve sexual function, etc., and these effects have been proved by modern medical research, such as amino acids and sterols in maca root have significant anti-fatigue effects, alkaloids, saponins Glycosides and other substances have a good regulatory effect on the endocrine of menopausal women, so that maca can replace and synthesize estradiol. Substances such as macaene, macamide and...
