Production method for extracting sweet tea glucoside from sweet tea leaves

A production method and rubusoside technology are applied in the field of rubusoside extraction, which can solve the problems that the market promotion level of industrialized large-scale production machines cannot be really reached, that the industrial production of rubusoside has not been reported, and that the application of rubusoside is limited. Separation, reduce solvent consumption, control foaming and run-off effect

Problems solved by technology

[0005] At home and abroad, studies on the separation, extraction, testing and pharmacology of rubusoside have been carried out, and there are also reports on the small-scale extraction of rubusoside with higher purity, but the industrial production of rubusoside with high content has not been reported, and in the process of extraction and separation A large number of toxic reagents are used for separation and purification, which has obvious restrictions on the application of rubusoside in food
This shows that the existing technical research is still in its infancy and cannot really reach the level of market promotion of industrialized large-scale production machines.

Embodiment 1

[0033] Take 500Kg of sweet tea leaves (the detected content is 5.2%), crush them and pass through a 40-mesh sieve, put them into the extraction tank, add 5000L of distilled water, heat to 80°C, reflux for 60min, suction filter while hot, add 4000L to the medicinal residues The distilled water is used for the second and third extractions, refluxed for 30 min / time under the same conditions, the first and second extractions are combined and concentrated to 500L, and the third extraction is used as water for the first extraction of the next batch. Add 350L ethanol to the concentrated solution to precipitate insoluble matter, filter, add the filtrate to the pretreated 50KgD101 resin column, the flow rate is 5BV / h, after the column is loaded, wash with purified water until the effluent is colorless, and finally elute with 70% ethanol , flow rate 1BV / h, collect 150L of the eluate, and concentrate to dryness. The sample was configured into an aqueous solution with a concentration of 2...

Embodiment 2

[0035]Take 500Kg of sweet tea leaves (the detected content is 5.4%), crush them to 40 mesh, put them into an ultrasonic extraction tank, add 5000L distilled water, ultrasonic output power 800W, ultrasonically extract at 80°C for 6min, filter, add 4000L distilled water to the medicinal residues again for extraction For the second and third extractions, after 6 minutes of extraction under the same conditions, the first and second extractions were combined and concentrated to 500L, and the third extraction was used as the next batch for the first water treatment. Add 350L ethanol to the concentrated solution to precipitate insoluble matter, filter, add the filtrate to the pretreated 50KgD101 resin column, the flow rate is 5BV / h, after the column is loaded, wash with purified water until the effluent is colorless, and finally elute with 70% ethanol , flow rate 1BV / h, collect 150L of the eluate, and concentrate to dryness. The sample was configured into an aqueous solution with a c...

Abstract

The invention provides a production method for extracting sweet tea glucoside from sweet tea leaves. The method comprises the following process flows of: smashing a sweet tea crude drug; extracting a solvent; concentrating; precipitating with alcohol; purifying with macroporous resin; concentrating; carrying out chromatography with polyamide resin; concentrating; crystallizing and recrystallizing; drying; and obtaining a finished product. By using the method, a high-quality sweet tea glucoside product can be produced, and the method also has the advantages of reducing the material loss, shortening the production period, improving the product yield and reducing the production cost and is suitable for the industrial production; the purity of the sweet tea glucoside produced by utilizing the method is higher than 98 percent, so that the product purity is high, and the component is single; the color of the sweet tea glucoside is white and good; and meanwhile, the technical difficulty of industrially producing a high-content and high-quality sweet tea glucoside extractive is overcome, so that large-scale production is smoothly produced.

Description

technical field [0001] The invention relates to a production method for extracting rubusoside from sweet tea leaves. Background technique [0002] Sweet tea is a perennial vine of Rosaceae. It is a rare and non-toxic, low-calorie, high-sweet and wild sweet-tasting plant unique to Guangxi. It is mainly produced in Yaoshan, Jinxiu, Yongfu and Cenxi counties and cities in Guangxi. . Because of its sweet taste, it is named sweet tea. Together with Mangosteen and Stevia, it is known as the three major sweet plants in Guangxi. It has a long history of application in Guangxi folks. For a long time, local people have been drinking it as tea, and also used it as a substitute for sugar to process food, and it can also be used as medicine. [0003] The main components of sweet tea are rubusoside, bioflavonoids, tea polyphenols, amino acids, inorganic salts, etc. [0004] The main sweet component of sweet tea leaves is rubusoside, which is a tetracyclic diterpene glycoside formed by ...
