Stevia rebaudiana Bertoni is a shrub-like plant of the Asteraceae family, originating from Paraguay and Brazil, where it is used as a sweetener for therapeutic preparations, such as teas and other beverages, for hundreds of years. It is often called “sweet Paraguay honey” (Genus, 2003). The sweetener compound is obtained from the leaves of the plant by extraction (Prakash et al., 2008). The swe...

Extracts from Stevia rebaudiana Bertoni, a plant native to Central and South America, have been used as a sweetener since ancient times. Currently, Stevia extracts are largely used as a noncaloric high-potency biosweetener alternative to sugar, due to the growing incidence of type 2 diabetes mellitus, obesity, and metabolic disorders worldwide. Despite the large number of studies on Stevia and ...

Now a day, various medicinal plants are becoming popular for the treatment of different diseases. Some medicinal plants are being used for the treatment of diabetes all over the world. The study was conducted to investigate the effects of powdered form of Stevia (Stevia rebaudiana Bertoni) leaves on blood glucose concentration and body weight in Streptozotocin induced diabetic rats and for its ...

Degradation of rebaudioside M, a minor sweet component of Stevia rebaudiana Bertoni, under conditions that simulated extreme pH and temperature conditions has been studied. Thus, rebaudioside M was treated with 0.1 M phosphoric acid solution (pH 2.0) and 80 °C temperature for 24 h. Experimental results indicated that rebaudioside M under low pH and higher temperature yielded three minor degrada...

In the present study, genetic diversity among 16 collections of Stevia rebaudiana Bertoni was assessed to compare the efficiency of two-marker systems over one marker using RAPD and ISSR markers. How well these two marker systems discriminated the Stevia collections was compared. In fact, all the Stevia accessions included in the present study have been growing under different altitudes, rangin...

Stevia rebaudiana Bertoni and Mentha piperita are plants that generate interest mainly due to the presence of bioactive compounds in their leaves, such as phenolics. Studies indicate phenolics have pharmacological therapeutic properties, including antioxidant activity. Phenolic may be affected by type fertilization. For this reason, organic chemical fertilization were evaluated along with Resul...

Stevioside is a naturally occurring diterpenoid glycoside in Stevia rebaudiana Bertoni. The title compound, C38H60O18·4CH3OH, crystallized as its methanol tetrasolvate. Stevioside consists of an aglycone steviol (a tetra-cyclic diterpene in which the four-fused-ring system consists of three six-membered rings and one five-membered ring) and a sugar part (three glucose units). A weak intra-molec...
