Method for extracting active ingredient from maca

Abstract

The invention discloses a method for extracting an active ingredient from maca. The method comprises the following steps of: performing vacuum drying on roots and stalks of the maca which are taken as a raw material, breaking walls, crushing, performing wet granulation, performing supercritical carbon dioxide extraction, separating to obtain a fat-soluble active substance in the maca, and extracting maca polysaccharide from maca extract residue by a hot water extraction method. According to the method, a functional active factor in the maca is extracted by a supercritical carbon dioxide extraction technology, and then the maca polysaccharide in the extract residue is extracted by the hot water extraction method; and the high-efficiency extraction and comprehensive utilization of the active ingredient in a maca raw material are realized by a separation and screening combination method from a crude extract to an effective part and the active ingredient.

Description

technical field [0001] The invention belongs to the technical field of extraction and purification of natural biological resources, and relates to a method for comprehensively utilizing maca and fully extracting effective components of maca. Background technique [0002] Maca (Maca) botanical name is Lepidium.meyenii Walp, which belongs to Brassicaceae and Lepidium genus. It is an annual herb plant and is a natural medicinal and edible plant. Native to the South American Andes at an altitude of 3500-4500m, it has been planted and eaten in South America for thousands of years. Maca is used in folk medicine to increase energy, improve fertility, relieve menopausal symptoms in postmenopausal women, depression, treat asthma, and promote wound healing, among others. However, due to the limitation of technological development level, the intensive processing level of Maca is low. For a long time, Maca has only been used as a common food or simply processed, such as processed into ...

Problems solved by technology

However, due to the low extraction efficiency, cumbersome separation steps, poor stability of active ingredients and unsuitability for large-scale production in the traditional separation, extraction and purification technology of active ingredients in Maca, it has seriously affected the use of Maca in the fields of biomedicine and health care products. development and application of

[0004] Chinese patent literature discloses a kind of extracting method of Maca, and the patent title of this patent is " Maca active ingredient extracting method ", and the patent No. is " 01138330.5 ", and the step of this method is: after fresh Maca root is vacuum-dried, Pulverized into powder for later use, maca root powder is not used CO 2 + entrainer for supercritical CO 2 Extraction technology extraction, get the extract, add water and emulsifier to the extract, vacuum evaporate the concentrate, spray dry and granulate after homogeneous emulsification, this method uses supercritical carbon dioxide extraction, which can keep the active ingredients in the extract, and reduce the high boiling point, Substances with low volatility and easy pyrolysis are extracted at a temperature far below their boiling point, and there is no solvent residue in the extract, which prevents the existence of harmful substances to the human body and pollution to the environment during the extraction process, ensuring 100% Natural, but because Maca contains fat components and water-soluble components, this method can not completely extract the effective components of Maca
