Embodiment 1

[0030] A kind of supercritical extraction method of Maca essential oil, comprises the following steps:

[0031] 1) Flour making: chop the root of Maca into 1cm 3 Dry in the sun until the water content is 10%, crush and granulate with a pulverizer, the particle size is controlled at 0.5cm, and dry in the sun until the water content is ≤ 2%, to obtain maca micropowder;

[0032] In step 1), first adopt the drying method to remove most of the water in Maca, and the remaining moisture in Maca can reduce the damage of mechanical force to the active ingredients of Maca on the one hand in the pulverization process, and on the other hand, it is convenient Granulation molding;

[0033] 2) Supercritical fluid dissolution: put the maca powder into the extractor, at 50°C and 35MPa pressure, use CO 2 Supercritical fluid extraction for 2 hours;

[0034] 3) Separation: CO 2 The pressure of the supercritical fluid extraction is adjusted to 27MPa, and the Maca essential oil is collected.

Abstract

The invention provides a supercritical extraction method of maca essential oil. The method comprises the three steps of pulverization, supercritical fluid leaching and separation. Mechanical wall breaking and granulation are performed to provide favorable conditions for extracting effective components in maca; by adopting a CO2 supercritical fluid leaching mode, the effective components in the maca are firstly extracted, and the effective components are converted into a free state in the CO2 supercritical fluid system; and the extraction pressure is lowered to selectively extract the effective components.

Description

technical field [0001] The invention relates to a method for extracting natural products, in particular to a method for supercritical extraction of maca essential oil. Background technique [0002] Maca (Lepidium meyenii Walp.) is native to the Andes Mountains above 3500m above sea level in Peru. It is a genus Lepidium of the Cruciferae family Cruciferae. It is a 1-year or 2-year-old herb and is known as Peruvian ginseng. Maca contains some other trace components such as catechol and other phenolic substances, saponins, benzyl thiohydrogen, Maca polysaccharides, Maca polypeptides, branched chain amino acids, carotenoids, flavonoids, uridine, tannins Wait. According to the current data and reports, Maca has the effects of improving fertility, improving sexual function, regulating endocrine, enhancing immunity, anti-oxidation, anti-stress, anti-fatigue and anti-cancer, and has the effects on rheumatism, respiratory diseases, depression, etc. , anemia, etc. have a good therap...
