Embodiment Construction

[0031] The following examples illustrate the invention in detail.

[0032] Take 100g of dried Luo Han Guo and break it into pieces with a diameter of about 1-2 cm. First boil 1000ml of tap water for 35 minutes, filter through a 60-mesh screen, and then boil the filter residue with 800ml of alkaline water (adjust the pH to 9 with NaOH) for 35 minutes, filter with a 60-mesh screen, and combine the two filtrates to obtain about 1800ml of extract. Concentrate the extract under reduced pressure at a temperature of about 60° C. to 1 / 20 of the original volume (about 90 ml). Use 500ml of 80% ethanol to fully mix the concentrated solution, let it stand for 1 hour, let it precipitate, and then vacuum filter with filter paper to obtain the precipitate (I) and the solution (II).

[0033] Precipitate (I) is dissolved with 500ml distilled water, pours in the glass column (diameter 25 millimeters, height 300 millimeters) that 100g201 * 7 styrenic anion resins are housed after filtering out ...

Abstract

The method for extracting and separating several components from Grosvenor's momordica fruit includes the following steps: washing Grosvenor's momordica fruit with water, using alkaline water to treat broken Grosvenor's momordica fruit to obtain extract, then using aliphatic alcohol to make treatment to obtain precipitate and dissolved liquor, making the precipitate pass through anion-exchange resin column and undergo the processes of aliphatic alcohol treatment and purification to obtain the Grosvenor's momordica fruit polysaccharide, and making the dissolved liquor pass through the polyamide resin column and macroporous resin column and undergo the process of aliphatic alcohol treatment to obtain Grosvenor's momordica fruit glycoside, and making the component adsorbed by polyamide resincolumn undergo the processes of washing with basic aliphatic alcohol.

Description

(1) Technical field: [0001] The invention relates to a method for extracting and separating various components such as mogroside polysaccharide mogroside and mogroside from grosvenoria. (two) background technology: [0002] Now, people generally only extract the active ingredient mogroside from Luo Han Guo, and the method used is to extract with water, and then concentrate and dry the water to obtain mogroside. This method can only obtain one active ingredient in Luo Han Guo, and the obtained product has complex ingredients and low total glycoside content. (3) Contents of the invention: [0003] The purpose of the present invention is to provide a method capable of extracting and isolating multiple active ingredients from Luo Han Guo, such as Luo Han Guo polysaccharides, Luo Han Guo flavonoids, and mogrosides. The products obtained by this method have relatively single ingredients and high content of main active ingredients . [0004] The object of the present invention ...
