Physiological and Enzymatic Evaluation of Selected Genotypes of Stevia rebaudiana Bertoni

Opinion on Stevia Rebaudiana Bertoni plants and leaves

Stevia rebaudiana Bertoni - chemical composition and functional properties.

Sweetleaf (Stevia rebaudiana Bertoni), currently investigated by many researchers, has been known and used for more than a thousand years indigenous tribes of South America, who called it "kaa-hee" ("sweet herb"). Thanks to its chemical composition and processability sweetleaf may be an alternative for synthetic sweeteners. Nutritional and health-promoting aspects of Stevia rebaudiana are prese...

Is Stevia rebaudiana Bertoni a Non Cariogenic Sweetener? A Review.

Stevia rebaudiana Bertoni is a small perennial shrub of the Asteraceae (Compositae) family that is native to South America, particularly Brazil and Paraguay, where it is known as "stevia" or "honey leaf" for its powerful sweetness. Several studies have suggested that in addition to their sweetness, steviosides and their related compounds, including rebaudioside A and isosteviol, may offer addit...

Additional minor diterpene glycosides from Stevia rebaudiana Bertoni.

Two additional novel minor diterpene glycosides were isolated from the commercial extract of the leaves of Stevia rebaudiana Bertoni. The structures of the new compounds were identified as 13-{β-D-glucopyranosyl-(1 → 2)-O-[β-D-glucopyranosyl-(1 → 3)-β-D-glucopyranosyl-oxy} ent-kaur-16-en-19-oic acid {β-D-xylopyranosyl-(1 → 2)-O-[β-D-glucopyranosyl-(1 → 3)]-O-β-D-glucupyranosyl-ester} (1), and 1...

Rapid in vitro propagation of Stevia rebaudiana Bertoni and evaluation of its stevioside content

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...
