Th e aim of this study was to analyze the chemical composition of apple purees of four diff erent apple varieties: ‘Golden Delicious’, ‘Idared’, ‘Jonagold’ and ‘Cripps Pink’, in the fresh state (FP) and aft er thermal treatment by process of pasteurization with added green (PG) or white stevia powder (PW) derived from the leaves of the stevia plant. Also, to determine whether there is a signifi...

This paper reports the possibility of monitoring the sweetener content in the leaves of Stevia Rebaudiana and root extract of Ginseng using FT-IR, micro-Raman and SERS techniques. Fingerprint analysis is a direct, fast, nondestructive and effective method to discriminate and identify different species. Ginseng root contains ginsengoside saponin about 4% and other active compounds such as D-gluc...

BACKGROUND Excess dietary fructose intake associated with metabolic syndrome and insulin resistance and increased risk of developing type 2 diabetes. Previous animal studies have reported that diabetic animals have significantly impaired behavioural and cognitive functions, pathological synaptic function and impaired expression of glutamate receptors. Correction of the antioxidant status of lab...

Stevioside is natural non-caloric sweetner isolated from Stevia rebaudiana BERTONI, which has been used as a non-caloric sugar substitute in Japan. Pezzuto et al. demonstrated that steviol shows a dose-dependent positive response in forward mutation assay using Salmonella typhimurium TM677 in the presence of metabolic activation system (Aroclor induced rat liver S9 fraction). Our studies were c...

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...

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...

MicroRNAs (miRNAs) usually contain 19-24 nucleotides and have been identified as important eukaryotic gene regulators. Applications of various computational approaches have simplified the task by predicting miRNAs from available sequence data sources. In this study, we identified a conserved miR414 from a computational analysis of EST sequence data available from Stevia rebaudiana. In addition,...

Stevia rebaudiana Bertoni is a Paraguayan perennial antidiabetic herb belongs to Asteraceae family. The Leaves of stevia are about 300 times sweeter than sugar with no calories, that are the source of diterpene glycosides such as stevioside and rebaudioside A. Tissue culture is a rapid tool for propagation of stevia. In this research we studied the effect of different concentrations of mannitol...

Aim: To assess the anticariogenicity of microwave-assisted 0.5% extract of Stevia rebaudiana leaves in high caries risk patients. Materials and methods: Forty-six patients with high risk for caries were selected. They were randomly assigned to two groups; group I was allocated for chlorhexidine (CHX) mouthwash (0.12% Perio-Aid) and group II for S. rebaudiana (0.5% extract of Stevia bio) mouthwa...

The experiment was conducted to evaluate the differences of plant growth as well as sweetener material of two types of Stevia rebaudiana under conditions of absence and presence of drought stress. In vitro, the experiment was conducted as drought traits using four levels of polyethylene glycol (0.0, 10,000, 20,000, 30,000 ppm). It was observed that survival % and No. of shoots should be conside...
