Abstract

The invention provides a method for extracting effective constituents from maca. The method includes the following steps that fresh or dry maca roots are taken as raw materials, the maca roots are washed, impurities are removed, an ethyl alcohol-water solution is used as homogenate liquid, the maca roots are homogenized, crushed and extracted, so that a homogenate extracting solution is obtained, filtering is conducted, filtering residues are mixed with an extraction solvent, negative pressure cavitation solid-liquid mixing cyclone extraction is conducted to obtain the extracting solution, the extraction solutions are combined and concentrated, a concentrated solution and a low-level solvent are mixed, then negative pressure cavitation liquid-liquid extraction is conducted, an extracting liquor is obtained, an extract is obtained after concentration, ethyl alcohol is added for redissolving, and thus a solution 1 is obtained; the extracted maca filtering residues are extracted again through hot water, an extracting solution is obtained after filtering, and a solution 2 is obtained after concentration; the solution 1 and the solution 2 are combined and dried, and extractives of the effective constituents of the maca are obtained. The method for extracting the effective constituents from the maca has the advantages that the technological process is simple, the production cycle is short, the effective constituents can be efficiently extracted, products can maintain the original flavor of the maca, used equipment is conventional equipment, production cost is low, and industrial production is easy to achieve.

Description

[0001] technical field [0002] The invention belongs to the field of natural product chemistry and plant extraction, in particular to a method for extracting active ingredients from Maca. Background technique [0003] Maca (Maca) belongs to the cruciferous family ( Cruciferae ) Lipeta ( Lepidium meyenii Walp.) plant, which is an annual herb. Native to the Andes in Peru at an altitude above 3500m, it is one of the important sources of food for local residents. In the process of eating for thousands of years, people have found that it has the effects of strengthening the body, improving fertility, improving sexual function, anti-depression and anti-anemia. [0004] Modern pharmacological research has found that the efficacy of maca is related to the various compounds it contains, such as alkaloids that can regulate endocrine glands and balance hormones; macaene and macamide have the effect of promoting sexual function; benzyl glucosinolate and benzyl Maca polysacchari...
