Problems solved by technology

However, the macroporous adsorption resin adsorption separation technology is a fixed-bed chromatography mode, and the biggest disadvantage is that it cannot directly process the feed material containing solid particles. Therefore, when used for the extraction of mogroside, it is necessary to pass the extract through a certain The pretreatment steps, such as extraction, centrifugation, filtration, concentration, and liquid-solid separation, can then be separated on the column. This process has cumbersome operations, long extraction time, low extraction efficiency, large equipment and space occupation, and labor and material resources consumption. Disadvantages such as large waste discharge, high production cost, etc.

Embodiment 1

[0025] See attached figure 1 with 2 , An integrated preparation method of mogroside, the specific steps are:

[0026] (1) After crushing Luo Han Guo, take 15 g of coarse powder, place it in extractor 1, add 300 ml of deionized water extract according to the material-to-liquid ratio of 1:20, and turn on the ultrasonic instrument for extraction;

[0027] (2) Turn on the pump at the same time of extraction, and transport the extracted liquid to the processed HZ-806 macroporous adsorption resin expanded bed chromatography column, the expansion ratio of the column bed is 1.5. After the extraction liquid is adsorbed by the macroporous adsorption resin, the remaining adsorption liquid flows back to the extractor to continue to participate in the extraction, forming a dynamic extraction of the extraction liquid, so that mogroside is adsorbed on the column bed;

[0028] (3) After 3 hours of extraction, turn off the sonicator, and pump 1 column volume (80 mL) of deionized water into the expand...

Embodiment 2

[0031] See attached figure 2 , An integrated preparation method of mogroside, the specific steps are:

[0032] (1) After crushing Luo Han Guo, take 50 g of coarse powder, place it in an extractor, add 1000 ml of deionized water extract according to the material-to-liquid ratio of 1:20, and turn on the ultrasonic instrument for extraction;

[0033] (2) Turn on the pump at the same time of extraction, and transport the extracted liquid to the processed HZ-806 macroporous adsorption resin expanded bed chromatography column, the expansion ratio of the column bed is 1.5. After the extraction liquid is adsorbed by the macroporous adsorption resin, the remaining adsorption liquid flows back to the extractor to continue to participate in the extraction, forming a dynamic extraction of the extraction liquid, so that mogroside is adsorbed on the column bed;

[0034] (3) After 3 hours of extraction, turn off the sonicator, pump 1 column volume (80 mL) of deionized water into the expanded bed ...

Abstract

The invention relates to an integrated preparation method for mogrosides. The preparation method includes: placing siraitia grosvenori into an ultrasonic extractor for extraction, starting a pump while extracting, feeding extracted solution into an expanded bed chromatographic column, and adsorbing residual solution to enable the same to flow back into the ultrasonic extractor to continue to take part in extraction; during extraction, mogrosides are constantly transferred from crude siraitia grosvenori onto resin in the expanded bed chromatographic column; and stopping the ultrasonic extractor after extraction is completed, conveying eluent into the expanded bed chromatographic column through the pump for elution, and collecting eluate into a collector. The integrated preparation method for mogrosides has the advantages of simplified steps, short extracting time and high efficiency.

Description

【Technical Field】 [0001] The invention relates to the technical field of extraction and separation of sweet glycosides in mogrosides, in particular to an integrated preparation method of mogrosides. 【Background technique】 [0002] Luo Han Guo is the fruit of Momordica grosvenori Swingle (Momordica grosvenori Swingle), a perennial herbaceous vine in the Cucurbitaceae family. It has high nutritional value and is rich in vitamin C, glycosides, glucose and protein. Its main chemical component is mogroside, which is a kind of non-sugar triterpenoid with strong sweetness. It has the functions of improving immune function, protecting liver, lowering blood sugar and blood lipid, and antioxidant. Since the last century, the role of Luo Han Guo has attracted the attention of scholars at home and abroad. [0003] The extraction of mogroside usually adopts methods such as soaking and refluxing, and then further separation and purification. Because mogroside is more polar and not easy to sepa...
