Rebaudioside A: Two-generation reproductive toxicity study in rats

Food and Chemical Toxicology, 2008
Rebaudioside A was administered via the diet to male and female Han Wistar rats at 0, 7500, 12,500, and 25,000ppm for two generations. Rebaudioside A treatment was not associated with any signs of clinical toxicity or adverse effects on body weight, body weight gain, or food consumption.

Biotransformation of stevioside to rebaudioside – A in suspension cells of Stevia: Applications of leaf extract in functional biscuits

Research journal of biotechnology, 2022
The suspension culture of Stevia was conceived as a means of establishing a stevioside-producing cell line in vitro. The highest callus induction rate (90%) was achieved using the Stevia leaf explants in modified MS medium supplemented with 1 mg/L BAP ...

Rebaudioside, a novel agent of glycoside clathration of pharmacons

Doklady Biological Sciences, 2009
205 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 ...

Combined enzymatic modification of stevioside and rebaudioside A

Applied Biochemistry and Microbiology, 2006
Cyclodextrin 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

RQ3, A Natural Rebaudioside D Isomer, Was Obtained from Glucosylation of Rebaudioside A Catalyzed by the CGTase Toruzyme 3.0 L

Journal of Agricultural and Food Chemistry, 2019
In this study, a monoglucosyl rebaudioside A product was isolated from the mixture of glucosylated rebaudioside A obtained from the most reported and industrial used cyclodextrin glycosyl transferase, Toruzyme 3.0 L (CGTase, Toruzyme 3.0 L). The molecular structure of the monoglucosyl rebaudioside A was characterized using LC-MS/MS and methylation ...

Developing polyploid genetic resources for enhanced rebaudioside A synthesis and agronomic traits in Stevia rebaudiana Bertoni

Plant genetic resources
Stevia rebaudiana Bertoni stores over 20 glycosides in leaves and stem, the primary sweetening compounds are stevioside and rebaudioside A. Stevioside is 250–300 times and rebaudioside A is 350–450 times sweeter than sucrose.

The non-cytotoxicity characterization of rebaudioside A as a food additive

Food and Chemical Toxicology, 2014
To 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 ...

Total Synthesis and Structural Revision of Rebaudioside S, a Steviol Glycoside

The Journal of Organic Chemistry, 2020
The total synthesis of rebaudioside S, a minor steviol glycoside from the leaves of Stevia rebaudiana, was investigated via a modular strategy, culminating not only in the first and highly efficient synthesis of Reb-S and analogues thereof but also in the revision of the originally proposed structure. The modular strategy dictated the application of C2-
