Abstract

The invention discloses a crystal form X of rebaudioside E, a preparation method and application thereof, and belongs to the field of chemical pharmacy. The technology provided by the present invention can. The present invention utilizes low-carbon alcohol water as a solvent, utilizes rubus glycoside to solubilize, and crystallizes to obtain rebaudioside E crystals whose crystal form is X, and overcomes the low solubility of rebaudioside E in alcohol-water solvents, so that Difficulty in obtaining crystals in large quantities with high efficiency. Using technical means such as XRD, DSC, TGA and polarized light microscopy to characterize the rebaudioside E crystal with crystal form X, it was found that the rebaudioside E crystal with crystal form X had high crystallinity, stable Good sex and other advantages. The preparation method involved in the invention is simple, easy to operate, good in reproducibility, and can stably obtain target crystals in batches.

Description

technical field

[0001] The invention relates to a crystal form X of rebaudioside E, a preparation method and application thereof, and belongs to the field of chemical pharmacy. Background technique

[0002] As a high-power sweetener, steviol glycoside is not only widely used in beverages, soy sauce, various marine foods, kimchi, candy and baked goods, but also has medicinal activity. It has hypoglycemic, anti-tumor, anti-inflammatory and Dental caries, antihypertensive, anti-inflammatory and antioxidant activities. Stevioside is non-fermentable, does not affect the coagulation and viscosity of food, is not prone to mildew, does not cause Maillard reaction during processing, and cannot be used by microorganisms, thereby prolonging the shelf life of stevia products and making it easy to store and transport.

[0003] Rebaudioside E is an isomer of rebaudioside A, which has similar polarity and is not easy to separate. Due to the low content of rebaudioside E in stevia rebaudi...
