Problems solved by technology

Although this method only needs to be separated through the column once, and then another deodorizer is needed to carry out the deodorization treatment, so the process is still more, the operation is complicated, and the cost is correspondingly higher.

[0008] 1) Take 1 gram of Momordica grosvenori, crush it, put it into water 8 times the weight of Momordica grosvenori, heat it to 100°C for 1 hour, and filter to obtain water extract A;

[0009] 2) Put the pomace in 7 times its weight in water, stir well, heat to 100°C and cook for 1 hour, filter to obtain water extract B;

[0010] 3) Take the pomace again and put it into 6 times its weight in water, stir well, heat to 100°C and decoct for 1 hour, filter to obtain water extract C;

[0011] 4) Combine the water extracts A, B, and C, filter and cool to 40°C;

[0012] 5) Adsorb the cooled filtrate with ADS-21 strong polar adsorption resin;

[0013] 6) The adsorbed resin is washed with water until it is clear and colorless;

[0014] 7) Elute the resin with 40% ethanol solution and collect the eluate;

[0015] 8) Recover the ethanol in the eluate, vacuum concentration, spray drying, and pulverization to obtain white mogroside powder with no astringency and no Chinese medicine taste. Determined...

Abstract

The invention discloses a method for extracting fructus momordicae sweet glycoside. The extraction method comprises the following steps: crushing fructus momordicae, extraction, absorbing the extraction liquid through a macroscopic absorbent resin, eluting the resin, collecting the eluent, and concentrating and drying the eluent; wherein the macroscopic absorbent resin can be an ADS-21, ADS-17, ADS-7 or an ADS-F8 macroscopic absorbent resin with strong polarity. Compared with the multiple column absorption method in the prior art in which extracting solution passes through an absorbent resin first and then passes through a decolorization resin and / or a deodorization resin, a decolored and deodorized fructus momordicae sweet glycoside product can be obtained only through one-time absorption separation carried out by the macroscopic absorbent resin with strong polarity without the decolorization and deodorization processes according to the method. The color of the prepared fructus momordicae sweet glycoside is white or similarly white which is different from the russet and pale yellow color of the prior fructus momordicae sweet glycoside. In addition, the sweetness of the fructus momordicae sweet glycoside is pure without bitterness or a traditional Chinese medicine taste, wherein the weight content of fructus momordicae gypenosides reaches as high as more than 95 percent, and the weight content of fructus momordicae sweet glycoside V reaches more than 65 percent.

Description

(1) Technical field: [0001] The invention relates to a method for extracting effective ingredients from natural plants, in particular to a method for extracting mogroside. (2) Background technology: [0002] Luo Han Guo, the fruit of perennial herbaceous vines in the Cucurbitaceae family, is an endemic plant in southern my country. It is mainly produced in northern Guangxi. The quality of Luo Han Guo is best in Guilin, Guangxi. Luo Han Guo has been eaten as a traditional Chinese medicine and beverage dried fruit for a long time. Its taste is extremely sweet, cool in nature, non-toxic, and enters the spleen and lungs. It quenches thirst, promotes gastrointestinal function, suppresses asthma and lowers blood pressure. Since the first report of mogroside fruits containing diterpene sweet glycosides in 1975, mogroside IV (mogroside IV), mogroside V, mogroside III, mogroside IIE, mogroside IIIE, and mogroside III have been isolated and identified from mogroside fruits. Mogroside VI,...
