Problems solved by technology

[0004] The traditional extraction methods of Chinese herbal medicine extraction and purification technology include decoction method, dipping method, percolation method, reflux method, etc. These methods generally have the disadvantages of low extraction rate of active ingredients, low removal rate of impurities, long production cycle, high energy consumption, Disadvantages such as large amount of solvent used; With the rapid development of modern industrial engineering technology, Chinese medicine engineering technology has made great progress, and some high-tech engineering technologies are constantly being used for reference in Chinese medicine production. On the one hand, Chinese medicine production is more in line with traditional Chinese medicine. Medical theory, to ensure the quality requirements of medication; on the other hand, it also improves the utilization rate of existing Chinese herbal medicine resources

Abstract

The invention discloses a method of preparing a Grosvenor momordica extract and the application thereof, which is realized through the following steps: 1. Grosvenor momordica is grinded and passes through 40-100 mesh sieve; mixed solvent is used for the extraction and the condensation; the molecular distillation of the first time is carried out on the condensed liquid to obtain a light component No.1 and heavy component No.2; the molecular distillation of the second time is carried out on the heavy component No.2 to obtain a light component No.3 and a heavy component No.4 which is a target component; the component No.4 is weighed, dissolved with ethanol of 75% and uniformly sprayed into blank cut tobacco to be prepared into cigarette evaluation; 2. extraction is carried out and the ethanol, propanediol and water are combined into mixed solvent in proportion rate of 2:3:5, wherein, the using amount of the mixed solvent is 6-20 times of the Grosvenor momordica powder, the extraction time is 1-5h, and the extraction is carried out for 2-4 times; 3. the condensation is carried out at the temperature of 80 DEG C and at the vacuum degree of 46Pa; 6. the adding amount is 0.01%. The Grosvenor momordica extract obtained by the invention can be well integrated with tobacco flavor.

Description

Technical field: [0001] The invention relates to the extraction and application of natural Chinese herbal spices, in particular to a preparation method and application of Luo Han Guo extract. Background technique: [0002] my country has abundant resources of Chinese herbal medicines. Many varieties are similar in chemical composition to tobacco, but have different curative effects, which can make up for the deficiency of tobacco in some aspects. Tobacco and Chinese herbal medicine have the same origin. Tobacco is a special natural herbal medicine. It is recorded in Chinese medicine books that tobacco has the effects of sedation, repelling miasma, and killing insects. Smoking its smoke after tobacco is made into cigarettes has the effect of excitement and refreshment. After thousands of years of development and experience accumulation, my country has unique advantages in the use of Chinese herbal medicines, which have laid a good foundation for us to develop low-harm cigare...
