Abstract

The invention discloses a method for extracting and purifying monomeric macamide compounds from maca. The method comprises the steps of smashing plant maca into maca powder, adding an alcohol-acid water solution to carry out multistage countercurrent extraction, and carrying out vacuum concentration after filtering an extracting solution to obtain crude macamide; and separating and purifying by using macroporous adsorption resin, carrying out gradient elution, collecting an eluant, and respectively carrying out vacuum concentration to obtain the monomeric macamide compounds. Because the macamide compound has favorable and stable physical properties under a weak acid condition, a multistage countercurrent extraction method is carried out by using the alcohol-acid water solution, and the alcohol-acid water solution can be used for protecting effective components of macamide during extraction and greatly increasing the extraction ratio of the effective components in maca plants; the macroporous adsorption resin can be repeatedly utilized; the alcohol-acid water solution serving as a solvent is economical and practical; the high-purity monomeric macamide compounds can be conveniently and efficiently obtained, and the purity of each monomeric compound is up to more than 95%; and the method is simple in process, simple and convenient to operate, low in cost and suitable for batch production.

Description

technical field [0001] The invention relates to a method for extracting and purifying a monomer compound of macamide from new resource food maca, belonging to the technical field of traditional Chinese medicine phytochemistry. Background technique [0002] Maca, also known as Maca (Maca, LepidiummeyemiiWalp), belongs to Cruciferae (Cruciferae). The locals mainly use it as food and can be used as traditional medicine. In 1982, with the efforts of international organizations such as FAO (Food and Agriculture Organization of the United Nations) and IPGRI (International Plant Genetic Resources Research Institute), Maca was widely promoted worldwide, and pointed out that Maca is a nutritionally safe food that can solve many diseases. health problems caused by nutritional deficiencies. In 2011, the Chinese government approved maca powder as a new resource food. Maca contains nutritional and active ingredients such as macamides and macaenes. It is a pure natural food that can pr...
