Genotoxicity studies on a high-purity rebaudioside A preparation
Food and Chemical Toxicology, 2009Rebaudioside A (Reb A) is a steviol glycoside isolated from the leaves of the Stevia rebaudiana plant. This non-nutritive, natural sweetener is reported to be 250-450 times sweeter than sucrose and has potential for wide use in the US diet, and is used in Japan and South America today.

NMR studies of the conformation of the natural sweetener rebaudioside A
Carbohydrate Research, 2009Rebaudioside A is a natural sweetener from Stevia rebaudiana in which four beta-D-glucopyranose units are attached to the aglycone steviol. Its (1)H and (13)C NMR spectra in pyridine-d(5) were assigned using 1D and 2D methods. Constrained molecular dynamics of solvated rebaudioside using NMR constraints derived from ROESY cross peaks yielded the ...

The non-cytotoxicity characterization of rebaudioside A as a food additive
Food and Chemical Toxicology, 2014To evaluate the cytotoxicity of high-purity rebaudioside A (reb A, 99.16%) as a food ingredient, a combination of several methods, including tetrazolium-based colorimetric assay (MTT), lactate dehydrogenase assay (LDH), enzyme-linked immunosorbent assay (ELISA), real-time PCR (qPCR), high-performance liquid chromatography (HPLC), and two-dimensional ...

Rebaudioside, a novel agent of glycoside clathration of pharmacons
Doklady Biological Sciences, 2009205 Glycyrrhizinic acid and stevioside, glycosides of higher terpenoids, are capable of in vivo formation of clathrates with pharmacons with various types of activity. This property of glycosides allows the effective dose to be substantially decreased (by a factor of 10– 100), with the basic activity being preserved and novel pharmacological effects ...

Investigations on the Stability of Stevioside and Rebaudioside A in Soft Drinks
Journal of Agricultural and Food Chemistry, 2010The stability of the two steviol glycosides stevioside and rebaudioside A and the possible formation of the aglycon steviol in different soft drinks were analyzed in samples spiked with stevioside or rebaudioside A after 24, 48, and 72 h storage times at 80 °C.

Combined enzymatic modification of stevioside and rebaudioside A
Applied Biochemistry and Microbiology, 2006Cyclodextrin glucanotransferases (CGTases, EC 2.4.1.19) produced by mesophilic, thermophilic, alkaliphilic, and halophilic bacilli were used for transglycosylating stevioside and rebaudiosides A with the use of starch as a donor. CGTases produced by B. stearothermophilus B-5076 B. macerans BIO-4m were the most effective biocatalysts. This method can be
