Following our interest in new diterpene glycosides with better taste profiles than that of Rebaudioside M, we have recently isolated and characterized Rebaudioside IX-a novel steviol glycoside-from a commercially-supplied extract of Stevia rebaudiana Bertoni. This molecule contains a hexasaccharide group attached at C-13 of the central diterpene core, and contains three additional glucose units...

Anti-human rotavirus (HRV) activity of hot water extracts from Stevia rebaudiana (SE) was examined. SE inhibited the replication of all four serotypes of HRV in vitro. This inhibitory effect of SE was not reduced on the prior exposure of SE to HCl for 30 min at pH 2. Binding assay with radiolabeled purified viruses indicated that the inhibitory mechanism of SE is the blockade of virus binding. ...

An efficient protocol was established for rapid in vitro propagation of Stevia rebaudiana Bertoni, using explants from mature plants. The effect of 1/2MS, MS and B5 culture media, also 27 different combinations of auxins and cytokinins was studied on in vitro growth and development of Stevia rebaudiana Bertoni. The best culture medium for shoot and root formation was 1/2MS, producing 1.30 shoot...

We investigated the influence of different conditions (light composition and plant growth regulators (PGRs) in culture media) on morphophysiological parameters Stevia rebaudiana Bertoni vitro vivo. Both PGRs light spectra applied were found to significantly affect morphogenesis. During micropropagation stage S. rebaudiana, optimal growth, with a multiplication coefficient 15, was obtained an MS...

Objective: Stevia (Stevia rebaudiana Bertoni) is a natural and healthyalternative sweetener to sugar and artificial sweeteners, which has become important for human diets and food manufactures. In this study, the effects of stevia or sucralose as tea sweeteners on glycemic and lipid profile of type 2 diabetic patients were investigated. Materials and Methods:</str...

The extract prepared from the leaves of Stevia rebaudiana BERTONI (Asteraceae) contains sweet steviol glycosides, mainly stevioside and rebaudioside A. Highly purified stevia extracts have become popular worldwide as a natural, low-calorie sweetener. They contain various types of steviol glycosides, and their main components are stevioside and rebaudioside A. The content of each steviol glycosi...

The need for medicinal and aromatic plants for industrial uses creates an opportunity for farmers to produce alternative crops. Stevia rebaudiana Bertoni, a perennial shrub originating from Paraguay, is of increasing interest as a source of zero-calorie natural sweeteners: the steviol glycosides (SVglys). The aim of this study was to investigate the relevance of nitrogen (N) supply for leaf yie...
