Stevia rebaudiana Bertoni

SCIENTIFIC COMMITTEE ON FOOD, Opinion on Stevia Rebaudiana Bertoni plants and leaves, SCF/NF/STE/3, Bmssels, European Commission, 1999. 

The plant Stevia rebaudiana bertoni has been studied in depth because it was discovered that this plant is the source of six sweet-tasting diterpene glycosides. They are stevioside, rebaudiosides A, C, D, E and dulcoside A. (Table 1). These sweet diterpene glycosides, as well as a complex mixture of organic compounds of which more than a hundred compounds have been identified, are found mainly in the leaves of the plant. The leaves contain a complex mixture of labdane diterpenes, triterpenes, stigmasterol, tannins and volatile oils. There is an abundance of reviews and patents relating to these sweet diterpene glycosides.

Stevia sweeteners are extracted from the leaves of Stevia rebaudiana Bertoni (Compositae), an herb native to Paraguay but cultivated in Southeast Asia, Japan, Paraguay, Brazil, Israel, and the United States. The sweet constituents of stevia include eight diterpene glycosides stevioside, ste-violbioside, rebaudiosides A, B, C, D, E, and dulcoside A, which collectively are 100-300 times... 

In the European Union there have been several petitions to approve stevia and its products. In 2000, the EU Commission refused marketing authorisation for Stevia rebaudiana Bertoni plants and dried leaves as a novel food or novel food ingredient (Official Journal of the European Communities, 2000). In October 2003, the SCF rejected a request to re-examine the restrictions on the uses of extracts of stevia. Its comment, after throroughly examining the evidence, was that the committee has serious doubts about the safety of stevioside and does not consider it acceptable for use in food (European Parliament, 2003).

Stevia rebaudiana Bertoni is a perennial shrub of the Asteraceae (Compositae) family native to certain regions of South America (Paraguay and Brazil). It is known to the Guarany people, native to these regions since time immemorial, by several names all of which refer to the sweet taste of the leaf, and especially to its use in mate tea Ilex paraguariensis). It is often referred to as the sweet herb of Paraguay .

Stevioside is an ent-kaurene type diteipenoid glycoside isolated from leaves of Stevia rebaudiana Bertoni. Leaves of this plant produce zero-calorie diterpene glycosides (stevioside and rebaudioside), a nmi-nutiitive, high-potency sweetener. Stevioside content in leaves will vary in field grown plants and is also influenced by agroclimatic conditions. Stevia leaves are also in use for their medicinal benefits. In this chapter, natural distribution and cultivation of Stevia,...
