Overview: The history, technical function and safety of rebaudioside A, a naturally occurring steviol glycoside, for use in food and beverages
Food Chem. Toxicol. 46 Suppl 7 , S1-S10, (2008) Rebaudioside A is a sweet tasting steviol glycoside extracted and purified from Stevia rebaudiana (Bertoni). Steviol glycosides can currently be used as a food ingredient in only a handful of countries. Questions on specifications, safety and special populati... |

Simultaneous determination of steviol and steviol glycosides by liquid chromatography-mass spectrometry.
Food Addit. Contam. Part A. Chem. Anal. Control. Expo. Risk Assess. 29(12) , 1861-71, (2012) A direct, versatile method for the determination of steviol and nine steviol glycosides in food products has been developed by using electrospray ionisation liquid chromatography-mass spectrometry in the negative-ion mode. Ten stevia compounds were readily se... |

Preparative separation and purification of rebaudioside a from steviol glycosides using mixed-mode macroporous adsorption resins.
J. Agric. Food Chem. 59(17) , 9629-36, (2011) Preparative separation and purification of rebaudioside A from steviol glycosides using mixed-mode macroporous adsorption resins (MARs) were systematically investigated. Mixed-mode MARs were prepared by a physical blending method. By evaluation of the adsorpt... |

NMR studies of the conformation of the natural sweetener rebaudioside A.
Carbohydr. Res. 344(18) , 2533-8, (2009) Rebaudioside 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 o... |

Optimizing the orosensory properties of model functional beverages: the influence of novel sweeteners, odorants, bitter blockers, and their mixtures on (+)-catechin.
J. Food Sci. 77(6) , S226-32, (2012) The use of flavor-modifying strategies are important to improving the sensory profile of some excessively bitter and astringent functional ingredients, such as (+)-catechin (CAT). Two bitter blockers (ß-cyclodextrin [CYCLO], homoeriodictyol sodium salt [HED])... |

Functional and structural variation of uridine diphosphate glycosyltransferase (UGT) gene of Stevia rebaudiana-UGTSr involved in the synthesis of rebaudioside A.
Plant Physiol. Biochem. 63 , 245-53, (2013) The sweetness of honey leaf plant Stevia rebaudiana is attributed to steviol glycosides or steviosides, accumulated in the leaves. Steviol glycosides are diterpenoids derived from steviol as the final step of glycosylation by the marker enzyme Uridine diphosp... |

Modulating efficacy of Rebaudioside A, a diterpenoid on antioxidant and circulatory lipids in experimental diabetic rats.
Environ. Toxicol. Pharmacol. 36(2) , 472-83, (2013) The present study was to evaluate the protective effects of Rebaudioside A (Reb A) on antioxidant status and lipid profile in streptozotocin (STZ)-induced diabetic rats. Diabetes was induced in Wistar rats by a single intraperitoneal administration of STZ (40... |
