stevia rebaudiana bertoni, is an ancient perennial shrub of south america, with great potential as a crop for the production of high-power natural sweetener. due to its chemical composition and content of the phytochemical compounds, it is suitable as a raw material for the extraction and production of functional foods. diterpene glycosides component of low-calorie sweetener is approximately 30...

The recent introduction of the cultivation of Stevia rebaudiana Bertoni in Mexico has gained interest for its potential use as a non-caloric sweetener, but some other properties of this plant require studies. Extracts from two varieties of S. rebaudiana Bertoni adapted to cultivation in Mexico were screened for their content of some phytochemicals and antioxidant properties. Total pigments, tot...

Stevioside is a natural sweetener extracted from leaves of Stevia rebaudiana (Bertoni) Bertoni. The literature about Stevia, the occurrence of its sweeteners, their biosynthetic pathway and toxicological aspects are discussed. Injection experiments or perfusion experiments of organs are considered as not relevant for the use of Stevia or stevioside as food, and therefore these studies are not i...

Sugars used for sweetening do contribute calories, which can lead to obesity, a risk factor for some chronic diseases. Hence, the craving for sweetness led to discover several forms of alternative sweeteners, which would offer consumers the sweet taste without calories. Stevia rebaudiana Bertoni is a natural herb with low calorie sweetener. Stevioside is one of the principal diterpene glycoside...

A new steviol diterpene glycoside, 13-[(2-O-β-D-glucopyranosyl-β-D-glucopyranosyl)oxy] ent-kaur-16-en-19-oic acid-{2-O-[6-O-β-D-glucopyranosyl)-βD-glucopyranosyl]-β-D-glucopyranosyl} ester (1) has been isolated from the commercial extract of the leaves of Stevia rebaudiana Bertoni. Structure of the new compound has been established on the basis of extensive NMR spectroscopy (H &C, TOCSY, HMQC, ...

BACKGROUND Traditional medicines with anti-diabetic effects are considered suitable supplements to treat diabetes. Among medicinal herbs, Stevia Rebaudiana Bertoni is famous for its sweet taste and beneficial effect in regulation of glucose. However, little is known about the exact mechanism of stevia in pancreatic tissue. Therefore, this study investigated the possible effects of stevia on pan...

The complete proton and carbon NMR spectral assignments of a diterpene glycoside isolated from the commercial extract of the leaves of Stevia rebaudiana Bertoni, 13-[(2-O-β-D-glucopyranosyl-3-O-β-D-glucopyranosyl-β-D-glucopyranosyl)oxy] ent-kaur-16-en-19-oic acid-[(2-O-α-L-rhamnopyranosyl-3-O-β-D-glucopyranosyl-β-D-glucopyranosyl) ester] (1); also known as rebaudioside N, was achieved by the ex...

Four steviol (ent-kaurene-type diterpenoid) glycosides, stevioside, rebaudiosides A and C, and dulcoside A, have been isolated from Stevia rebaudiana BERTONI. These compounds showed strong inhibitory activity against 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced inflammation in mice. The 50% inhibitory dose of these compounds for TPA-induced inflammation was 54.1-291.6 micro g/ear. Further...

Background: Despite the medicinal importance of Balanites aegyptiaca (L.) Del, Stevia rebaudiana (Bert.) Bertoni, Tylophora indica (Burm.f.) Merrill and Cassia sophera (Linn.), the antimicrobial potential of these plants has not been explored extensively, especially those of Cassia sophera. Methods: Both aqueous and alcoholic extracts of various parts of respective plants, and their in vitro ra...
