The aim of the present study was to reveal an effective extraction procedure for maximization of the yield of steviol glycosides and total phenolic compounds as well as antioxidant activity in stevia extracts. Ultrasound assisted extraction was compared with conventional solvent extraction. The examined solvents were water (100oC/24 ...

Stevia rebaudiana Bertoni is a shrub having a high content of sweet diterpenoid glycosides in its leaves, mainly stevioside and rebaudioside A, which are used as noncaloric, natural sweeteners. The aim of this study was to deepen the knowledge about the insulin-mimetic effect exerted by four different mixtures of steviol glycosides, rich in stevioside and rebaudioside A, in neonatal rat cardiac...

Stevia rebaudiana Bertoni is a plant species which frequently used not only as sweetener, but also for its antibacterial and antioxidant properties. Nowadays, there are large number of studies on the antimicrobial activity S. leaves, almost no data about potential extracts from other parts rebaudiana. The aim present study to provide methanolic different (flowers, stems, rhizomes, tubers) culti...

The micropropagation of Stevia rebaudiana using stem node segment explants obtained from 2 years-old shrubs were achieved. Cultures were established on Murashige and Skoog (MS) as the medium supplemented with different concentrations of 6-benzylaminopurine (BA) at concentration, 0.0, 0.1 and 0.5 mg/l individually or in combination with Kinetin (Kin) at concentration, 0.0, 0.1 and 0.5 mg/l. The ...

Stevia as a natural sweetener with zero calories, and proven non-toxic effects on human health, recently found widespread use in the food and baking industry. Steviol glycosides that are concentrated in the plant leaves are: even 300 times sweeter than sucrose, heat-stable and well tolerate low pH-values. Th ese are all characteristics that popularize this plant in its application as a natural ...

On the other hand, reports published by The European Food Safety Authority [4] indicate that low concentrations of low-calorie sweeteners are safe to be consumed by humans. Further research is needed to relate the results obtained from animal studies in or...
