Objective: Stevia (Stevia rebaudiana Bertoni) is a natural and healthyalternative sweetener to sugar and artificial sweeteners, which has become important for human diets and food manufactures. In this study, the effects of stevia or sucralose as tea sweeteners on glycemic and lipid profile of type 2 diabetic patients were investigated. Materials and Methods:</str...

Purpose: The purpose of the study is to evaluate the antimicrobial and antitumor activities of Stevia rebaudiana (Asteraceae) leaf extracts. Methods: Four solvent extracts (ethyl acetate, acetone, chloroform and water) of Stevia rebaudiana leaves were investigated against Staphylococcus aureus, Salmonella typhi, Escherichia coli, Bacillus subtilis, Aeromonas hydrophila and Vibrio cholerae by us...

The paper presents the results of studies effect stevia powder on quality gluten-free cookies with a complete replacement sugar in recipe. were made from mixture rice and corn flour (40/60). Margarine or vegetable oil used as fat components. Stevia was different amounts: 1.0; 2.0; 3.0%. Cookies assessed by organoleptic indicators, physical characteristics (diameter, thickness), moisture, swelli...

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...

In recent years there has been increasing demand for natural non-nutritive high intensity sweeteners with low-calorie value as an alternative to sucrose. Extracts of the leaves of Stevia rebaudiana (Bertoni), have been known for their sweet taste. Steviosides and rebaudioside-A are the two major diterpenoid glucosides components present in the leaf extracts of the stevia, these glycosides are 3...

Steviol glycosides are found in high concentrations in the leaves of the Paraguayan perennial herb Stevia rebaudiana and their intense sweetness, as well as high concentration in Stevia leaf tissue, has made them the subject of research interest for over 100 years. Steviol glycosides are diterpenoids whose biosynthetic pathways share four steps in common with gibberellic acid formation. The con...

From the commercial extract of the leaves of Stevia rebaudiana Bertoni, a minor steviol glycoside, 13-[(2-O-β-D-glucopyranosyl-3-O-β-D-glucopyranosyl-β-D-glucopyranosyl)oxy] ent-kaur-16-en-19-oic acid-[(2-O-(3-O-β-D-glucopyranosyl-α-L-rhamnopyranosyl)-3-O-β-D-glucopyranosyl-β-D-glucopyranosyl) ester] (1); also known as rebaudioside O having seven sugar units has been isolated. Its structural ch...

Basic hydrolysis of a dichloromethane extract of Stevia lucida yielded (4R,5S,7R,9R,10R,11R)-7,9-dihydroxylongipin-2-en-1-one (1), which was oxidized and subjected to acidic conditions to generate the new seco-moreliane derivative 3. The structure of 3 was established based on NMR data interpretation and confirmed computationally. A plausible mechanism for the carbocationic rearrangement of the...

Previous research has shown a correlation between blood sugar or glycemic load and cancer growth for a number of types of cancer. Those studies were retrospective and/or studies of fewer than 20 human subjects and/or studies on mice. This study is a 7-year interventional study of 317 human patients at one clinic, who were treated naturopathically, with anti-neoplastic nutrients and herbs, plus ...
