Abstract

The invention discloses an extraction method for natural high-purity mogroside. The method includes: crushing siraitia grosvenorii into nanoscale fine powder, then conducting water ultrasonic extraction and concentration to obtain an extract, dissolving the extract with water, then using a supramolecular solvent formed by tetrahydrofuran and water to remove fat soluble impurities from the extract, and finally using ethyl acetate to perform washing, and then conducting drying, thus obtaining a high-purity mogroside extract. The method provided by the invention has no need for using special separation membrane and column chromatography, has the characteristics of simple extraction process, short extraction time, and significantly reduced consumption of organic solvent, thus being more efficient and environmental friendly. In addition, the high-purity mogroside obtained by the method provided by the invention can be directly used as a food sweetness additive.

Description

technical field [0001] The invention relates to the technical field of extraction of plant active ingredients, and relates to a method for extracting natural high-purity mogroside. The obtained high-purity mogroside can be directly used as a natural sweetener for food. Background technique [0002] Mangosteen is mainly produced in the mountainous areas of Lingui County and Yongfu County, Guilin City, Guangxi, my country, and is occasionally planted in other provinces. Luo Han Guo fruit has high nutritional value, rich in vitamin C, E, fructose, essential amino acids, trace elements and other nutrients, as well as various active ingredients such as flavonoids, polysaccharides, sweet glycosides and polyphenols. Japanese scholar Takemoto Changmatsu found that the main effect of Luo Han Guo on various diseases is the substance contained in the fruit that is 300 times sweeter than sugar-mogroside, scientifically named "cucurbitacin triterpene", which belongs to the triterpene It...
