Steviol Glycosides: Chemical Diversity, Metabolism, and Function

Journal of Natural Products, 2013
Steviol glycosides are a group of highly sweet diterpene glycosides discovered in only a few plant species, most notably the Paraguayan shrub Stevia rebaudiana. During the past few decades, the nutritional and pharmacological benefits of these secondary metabolites have become increasingly apparent.

Steviol and Steviol-Glycoside: Glucosyltransferase Activities in Stevia rebaudiana Bertoni - Purification and Partial Characterization

Archives of Biochemistry and Biophysics, 1995
The leaves of Stevia rebaudiana Bertoni contain sweet compounds which are glycosides of diterpene derivative steviol (ent-13-hydroxykaur-16-en-19-oic acid). Its main constituents are stevioside (triglucosylated steviol; 13-O-beta-sophorosyl-19-O-beta-glucosyl-steviol) and rebaudioside-A (tetraglucosylated steviol; 2'-O-beta-glucosyl-13-O-beta ...

Membrane separation processes for the extraction and purification of steviol glycosides: an overview

Critical Reviews in Food Science and Nutrition, 2020
Steviol glycosides (SGs), as natural sweeteners from Stevia rebaudiana, are currently employed for replacing sugar and its derivatives in several food products and formulations. Such compounds play an essential role in human health. Their usage provides a positive effect on preventing diseases related to sugar consumption, including diabetes mellitus ...

UDP-dependent glycosyltransferases involved in the biosynthesis of steviol glycosides

Journal of Plant Physiology, 2011
A short-term experiment was designed to measure the transcript levels of downstream genes contributing to the biosynthesis of steviol glycosides. Stevia rebaudiana plants were subjected to long- and short-day conditions for different time intervals. Samples from both lower and upper leaves were collected.

Convergent synthesis of steviol glycosides rebaudioside a and M

Carbohydrate Research
Steviol glycosides, a natural health-focused sweetener, is receiving increasing attention. Herein, an efficient and concise approach for the convergent synthesis of Rebaudioside A and M has been devised. This method features a AuCl3-tBuCN cooperative catalysis to achieve highly 1, 2-trans stereoselective glycosidation of a C2-branched trisaccharide ...

Beaming steviol glycoside analysis into the next dimension

Food Chemistry, 2018
Nine state-of-the-art reversed phase (RP) columns for ultra-high performance liquid chromatography were tested for the separation of steviol glycosides. The main criteria were resolution of the critical peak pair rebaudioside A and stevioside and the retention time of rebaudioside D.

Influence of Steviol Glycosides on the Stability of Vitamin C and Anthocyanins

Journal of Agricultural and Food Chemistry, 2014
A high level of sweetness and health-promoting properties make steviol glycosides an interesting alternative to sugars or artificial sweeteners. The radical oxygen species scavenging activity of these compounds may influence the stability of labile particles present in food.

CHAPTER 9. Steviol Glycosides in Dentistry

2018
Fermentable carbohydrates are implicated in the etiology of oral biofilm-associated diseases such as gingival inflammation and dental decay. Therefore, sweeteners were introduced into preventive dental care to replace sucrose. The preventive potential of sugar substitutes is widely recognised.

Steviol-glycosides: New natural sweeteners

TrAC Trends in Analytical Chemistry, 1982
Abstract The need for a safe, non-nutritive sweetener for the diabetic and the diet conscious has prompted the further investigation of new sweeteners of plant origin. This review deals with the chemistry of sweet steviol-glycosides, which are currently used as a food-additive in Japan.

CHAPTER 4. Analysis of Steviol Glycosides

2018
In this chapter actual trends in sample preparation, determination, detection and quantification of steviol glycosides were reviewed beginning with the first official method for the analysis of steviol glycosides published in 1993. Before analysis, various sample preparation techniques have to be applied depending on the type of sample.
