Embodiment 1

[0119] This practice extracts multiple active ingredients from dried Luo Han Guo and includes the following steps:

[0120] The first step: flash auxiliary preparation of the first liquid mixture

[0121] Put the cored dried Luo Han Guo and deionized water into a flash extraction container, soak at a temperature of 25°C for 120 minutes, stir and break at a rotation speed of 3500r / min, and homogenize for 60s to obtain the first liquid mixture;

[0122] Dosage: Add 10g of pitted and dried Luo Han Guo to 100ml of deionized water;

[0123] Step 2: Centrifugation

[0124] Put the first liquid mixture into the centrifuge tube of the centrifuge, centrifuge at a speed of 5000r / min for 15min, then remove the centrifuge tube to obtain the first supernatant and the first precipitate;

[0125] The third step: making sweet glycosides

[0126] (3-A) Add 0.65% (mass percentage concentration) of NaCl in the first supernatant liquid, then use 25%

Abstract

The invention discloses a method for extracting various active components from dried fructus momordicae, which belongs to the technical field of extraction separation of the effective components of natural products. The method comprises the following steps: firstly, denucleating the dried fructus momordicae; then carrying out watering flash extraction and centrifugation on peel and pulp to obtain precipitates and a supernate; respectively carrying out XAD chromatography for two times or upper polyamide-XAD chromatography and D213 column decoloration on the supernate to obtain mogroside and polyphenol; carrying out acid solution extraction and D113 column separation on the precipitates to obtain alkaloid; carrying out concentration and ethanol fractional precipitation on waste liquid to obtain polysaccharide and oligosaccharide; and hydrolyzing waste residues by using gastric enzymes to obtain the polysaccharide, the oligosaccharide and amino acids. The invention realizes the comprehensive utilization of the medicinal materials of the fructus momordicae, reduces the production cost and increases the additional value and the economic benefit of the product by adopting an advanced extraction technology.

Description

technical field [0001] The invention relates to a separation method of natural products, more particularly, refers to a preparation method for obtaining various active components in Luo Han Guo through resin separation by adopting flash auxiliary extraction technology. Background technique [0002] Included in the "Chinese Pharmacopoeia" published in 2005, Luo Han Guo is a plant of Cucurbitaceae. Its ripe fruits are sweet in taste and cool in nature, and have the effects of clearing away heat and moistening the lungs, smoothing the intestines and laxative. Luo Han Guo is a traditional medicinal plant in my country. It has high nutritional value and is rich in sugar, protein, vitamins, fatty acids and various amino acids and trace elements. It is known as the "Oriental God Fruit". [0003] The main active ingredient in Luo Han Guo is the intensely sweet triterpenoid mogroside, which accounts for about 4% by weight of the dried fruit. It is a low-calorie natural sweetener, 3...
