Embodiment 1

[0019] (1) Wash the fresh maca rhizomes, dry the surface moisture, cut off the fine roots other than the maca bulbous roots, chop them up with a ceramic knife and set aside;

[0020] (2) According to the ratio of solid to liquid (kg / L) 1:3, mix the chopped fine roots in step (1) with pH=2 and 70v / v% ethanol aqueous solution, and then seal and soak at room temperature for 6 hours , and then filtered at 10°C to obtain the filtrate, use 2wt% hydrochloric acid solution or 1wt% NaOH solution to adjust the pH of the filtrate to neutral, then add pure water to the filtrate to make the ethanol concentration 15v / v%;

[0021] (3) Cool the filtrate treated in step (2) to below -20°C at a cooling rate of 8°C / min, make it completely solid, and then pulverize it to obtain solid particles;

[0022] (4) Place the solid particles obtained in step (3) in an extraction kettle for supercritical CO extraction under the following conditions: 2 Extraction for 40min: extraction temperature is 15°C, ...

Embodiment 2

[0025] (1) Wash the fresh maca rhizome, dry the surface moisture, cut off the root bark of the maca bulbous root, chop it with a ceramic knife and set it aside;

[0026] (2) According to the material-to-liquid ratio kg / L of 1:10, mix the root bark after step (1) with pH=4 and 30v / v% ethanol aqueous solution, and then seal and soak at room temperature for 12 hours , then filter at 0°C to obtain the filtrate, use 2wt% hydrochloric acid solution or 1wt% NaOH solution to adjust the pH of the filtrate to neutral, then add pure water to the filtrate to make the ethanol concentration 12v / v%;

[0027] (3) Cool the filtrate treated in step (2) to below -20°C at a cooling rate of 10°C / min, make it completely solid and then pulverize it to obtain solid particles;

[0028] (4) Place the solid particles obtained in step (3) in an extraction kettle for supercritical CO extraction under the following conditions: 2 Extraction for 90min: extraction temperature is 20°C, extraction pressure is ...

Embodiment 3

[0031] (1) Wash the fresh maca rhizomes, dry the surface moisture, cut off the root bark of the maca bulbous roots and the fine roots other than the bulbous roots, chop them up with a ceramic knife and set aside;

[0032] (2) According to the ratio of material to liquid kg / L 1:2, the root bark and fine roots chopped in step (1) are mixed with ethanol aqueous solution with a pH=5 and a concentration of 80v / v%, and then sealed at room temperature Soak for 3 hours, then filter at 5°C to obtain the filtrate, use 2wt% hydrochloric acid solution or 1wt% NaOH solution to adjust the pH of the filtrate to neutral, then add pure water to the filtrate to make the ethanol concentration 10v / v%;

[0033] (3) Cool the filtrate treated in step (2) to below -20°C at a cooling rate of 6°C / min, make it completely solid, and then pulverize it to obtain solid particles;

[0034] (4) Place the solid particles obtained in step (3) in an extraction kettle for supercritical CO extraction under the fol...

Abstract

The invention discloses a method for extracting maca essential oil. The method comprises the following steps: cleaning maca roots and stems, air-drying to remove water on surfaces, then cutting root barks of spherical maca roots and / or fine roots besides the spherical maca roots, and cutting into pieces for later use; then mixing the pieces with an ethanol aqueous solution; performing sealed soaking at normal temperature; then performing low-temperature filtration to obtain a filtrate; adjusting the pH of the filtrate to be neutral; adding pure water into the filtrate; then cooling to ensure that the filtrate is completely frozen into a solid state, and crushing to obtain solid particles; performing supercritical CO2 extraction on the solid particles, and collecting the maca essential oil. According to the method disclosed by the invention, the yield of the maca essential oil reaches more than or equal to 0.25%, the content of glucosinolate accounts for more than or equal to 20.2% of the essential oil, and the mustard pungent taste in the essential oil can be kept for 36-72 hours at normal temperature. The essential oil can avoid decomposition and disassimilation of aromatic glucosinolate, so that the essential oil is good in quality, is rich in aroma and pure in mustard pungent taste, and does not have odors and other peculiar smells after decomposition of glucosinolate.

Description

technical field [0001] The invention belongs to the fields of natural product chemistry and plant extraction, and in particular relates to a method for extracting maca essential oil. Background technique [0002] Maca (Maca) is a herb of the genus Brassicaceae ( Lepidium meyenii Walp.), native to South America, is a functional food with great medicinal value and economic significance. The basic research of its efficacy shows that Maca is rich in mineral elements, amino acids, vitamins and other nutrients, as well as secondary metabolites such as alkaloids, sterols, glucosinolates, etc. It has activities such as improving sexual function, anti-aging, anti-tumor, and anti-oxidation. . [0003] Among them, glucosinolate is a kind of hydrophilic plant secondary metabolites containing nitrogen and sulfur, and it is one of the main functional components in maca root, mainly distributed in maca leaves and maca roots. The main constituents of essential oils. The glucosinolates ...
