Embodiment 1

[0015] Embodiment 1 of the present invention: the preparation method of decolouring, debittering Luo Han Guo extract, its steps are as follows:

[0016] 1) Wash the fresh Luo Han Guo fruit, and kill it in hot water at 90°C for 1 minute;

[0017] 2) crush the dried Luo Han Guo and squeeze the juice, put the residue in 4 times the weight of pure water and soak it at room temperature for 4 times, and squeeze to obtain the squeeze liquid;

[0018] 3) Combine the fruit juice and squeezed liquid, centrifuge to remove impurities, and put the supernatant into ADS-21 macroporous adsorption resin;

[0019] 4) Wash the adsorption resin with water until the effluent is colorless, then elute with a 1% (weight percentage concentration) sodium carbonate solution 6 times the weight of the resin to remove pigment and impurities, and then wash with pure water until the effluent is neutral;

[0020] 5) elute the adsorption resin with 4 times the weight of the resin in 65% ethanol to remove the ...

Embodiment 2

[0023] Embodiment 2 of the present invention: prepare decolorization, debitter Luo Han Guo extract according to the following steps:

[0024] 1) Wash the fresh Luo Han Guo fruit, and kill it in hot water at 85°C for 1 minute;

[0025] 2) crush the dried Luo Han Guo and squeeze the juice, soak the residue in 5 times the weight of pure water at room temperature for 2 times, and squeeze to obtain the squeeze liquid;

[0026] 3) Combine the fruit juice and squeezed liquid, centrifuge to remove impurities, and use ADS-7 type macroporous adsorption resin to absorb the centrifuged supernatant;

[0027] 4) Wash the adsorption resin with water until the effluent is colorless, then elute with 2% (weight percentage concentration) sodium bicarbonate solution 10 times the weight of the resin to remove pigment and impurities, and then wash with pure water until the effluent is neutral;

[0028] 5) Elute the adsorption resin for removing pigment and impurities with 35% ethanol solution 6 ti...

Embodiment 3

[0031] Embodiment 3 of the present invention: prepare decolouring, debittering Luo Han Guo extract according to the following steps:

[0032] 1) Wash the fresh Luo Han Guo fruit and kill it in 80°C hot water for 2 minutes;

[0033] 2) crush and squeeze the dried Momordica grosvenori, soak the residue in 3 times the weight of water at room temperature for 5 times, and squeeze to obtain squeezed liquid;

[0034] 3) Combine the fruit juice and squeezed liquid, centrifuge to remove impurities, and put the supernatant into ADS-8 macroporous adsorption resin;

[0035] 4) Wash the adsorption resin with water until the effluent is colorless, then elute with 0.2% (weight percent concentration) sodium hydroxide solution twice the weight of the resin to remove pigment and impurities, and then wash with water until the effluent is neutral;

[0036] 5) eluting the adsorption resin for removing pigment and impurities with 50% ethanol solution twice the weight of the resin, and collecting t...

Abstract

The invention discloses an extractive of discoloring, debitterizing corsvenor momordica fruit and a preparation method thereof, the method is as follows: the corsvenor momordica fruit is cleaned, crushed and extracted to juice, the fruit juice is centrifugated, the supernatant fluid enters into the macroporous absorption resin, the resin is washed by water, alkali solvent and water in order, till the effluent liquid is neutral; and then is eluted by 30 percent -65 percent ethanol, the ethanol eluent is collected, ethanol is recovered and dried, and then the extractive is obtained. The technology is simple, the production cost is low, and the production is easy to control; the traditional heating extracting method is replaced by extracting the juice, so the energy consumption is reduced, the color of the obtained extractive is light, the impurity is little, and the product quality is better; the adopted absorption resin achieves better discoloring, debitterizing effects at the same time of enriching the active components completely, the content of momordica glycosides is improved, the pigment and the impurity in the extractive are removed completely through eluting; the obtained product is white powder, the taste is sweet and pure, without traditional bitter taste, wherein, the gypenosides weight content of momordica glycosides can reach over 90 percent, and the V weight content of momordica glycosides can reach over 60 percent.

Description

(1) Technical field: [0001] The invention relates to a decolorized and debittered mangosteen fruit extract and a preparation method thereof, belonging to the technical field of extraction of medicinal active ingredients. (two) background technology: [0002] Luo Han Guo is sweet, sour, cool in nature, and returns to the lung and large intestine meridian. Constipation and other symptoms of blood dryness can be used to treat obesity, diabetes, acute and chronic bronchitis, tonsillitis, pharyngitis, acute gastritis, asthma, high blood pressure and diabetes, etc. , thirst, irritability, etc. The main components of Luo Han Guo extract are mogrosides, including mogrosides IIE, III, IIIE, IV, V and VI, mogroside alcohol, simonoside I, 1-carbomogroside V, and mogrosides, and mogrosides among them V is the main component of its sweetness. Due to its high sweetness and low calorie, pharmacological tests have shown that mogroside has the activity of lowering blood pressure and blood...
