Abstract

The invention discloses a method for simultaneously extracting Mogroside V and VI and 11-O-based glucoside V. The method comprises the following steps: (1) dissolving Mogroside V refining mother solution, extracting by n-butyl alcohol to obtain a n-butyl alcohol layer; (2) concentrating, cooling, crystallizing, and filtering to obtain a crystal and crystallization mother solution, and drying the crystal to obtain the Mogroside VI; (3) concentrating the crystallization mother solution until the alcohol is not existent, dissolving, and passing through a polyamide chromatography column, collecting effluent, concentrating, and drying to obtain the Mogroside V; (4) eluting the chromatography column by using the low-concentration alcohol and the high-concentration alcohol, collecting high-concentration alcohol eluant, concentrating, cooling, crystallizing, filtering, and drying to obtain Momordica grosvenori 11-O-based glucoside V. The purity of the Mogroside VI obtained by the method is greater than or equal to 97%, and the yield is greater than or equal to 83%; the purity of the Mogroside V is greater than or equal to 89%, and the yield is greater than or equal to 89%; and the purity of the 11-O-based glucoside V is greater than or equal to 96%, and the yield is greater than or equal to 85%. The condition of the method is moderate, safe and environmental, and the method is suitable for the industrial production.

Description

technical field [0001] The invention relates to a method for extracting mogroside, in particular to a method for simultaneously extracting mogroside V, VI and 11-O group glycoside V. Background technique [0002] Luo Han Guo is a traditional medicinal and edible plant in my country. Mogroside is its main functional component. It is an ideal natural sweetener with high sweetness and low calories. It has attracted people's attention because of its various biological activities. . There are many kinds of mogrosides. Studies have shown that mogrosides are a kind of triterpene glucoside, and its aglycone is a triterpene alcohol. There are two glucoside side chains composed of four or less glucose units. -Glycosidic bonds are connected to aglycones, and the connecting bonds between side chain glucose and sugar are β-1,6 and β-1,2 glycosidic bonds. Among them, mogroside V has the highest content, followed by 11-O-based glycoside V and glycoside VI. The molecular formulas of the th...
