Leaves of Stevia rebaudiana Bertoni have been popularly used as a sweetener in foods and beverages for diabetics and obese people due to their potent sweetener stevioside. In this report, stevioside and steviol were tested for mutagenicity in Salmonella typhimurium strains TA98 and TA100 and for chromosomal effects on cultured human lymphocytes. Stevioside was not mutagenic at concentrations up...

Background: Stevia is nontoxic and non-caloric sweetens nearly 300 times more sweetener than any other source. Numerous health benefits for chronic patients its reach source of essential nutrients pooling the world. Objective: This study tried analyzed effect black cumin added in stevia apple jam place sugar as functional ingredient due to promoting effects case hypertension. Method: A stevia-s...

*Corresponding author e-mail: [email protected] A b s t r a c t. The aim of the present study was to reveal an effective extraction procedure for maximization of the yield of steviol glycosides and total phenolic compounds as well as antioxidant activity in stevia extracts. Ultrasound assisted extraction was compared with conventional solvent extraction. The examined solvents were water (100oC/24 ...

Stevia rebaudiana is a sweet herb of the Astraceae family, which is cultivated for the natural sweeteners it contains. The aim of this study was to assess the effect of drought, simulated by the application of polyethylene glycol (5%, 10%, and 15% w/v), on the content of steviol glycosides (SVglys) and transcription levels of six genes involved in the biosynthesis of these natural sweeteners. T...

Anti-inflammatory activities of methanolic extract of callus and intact plant part of Stevia rebaudiana(Bert.) Bertoni was studied for the first time. Acute inflammation model, carrageenan induced rat hind paw edema model was employed to investigate the anti-inflammatory activity. The methanolic extract from fresh callus cultures of Stevia rebaudianacultured on Murashige and Skoog (MS) medium f...

Stevia (Stevia rebaudiana Bertoni) produces steviol glycosides (SG), a group of diterpenoid secondary metabolites widely used as natural sweeteners. SGs share the same precursor with gibberellins (GAs), ent-kaurenoic acid. In this study, we attempted to increase SG content in stevia propagated Temporary Immersion Bioreactors (TIBs) by blocking acid entry GA synthesis pathway using Daminozide (0...

Stevia rebaudiana is a sweetener herb belongs to Asteraceae family, native Argentina, Brazil and Paraguay. has potential qualities of also constituting source many substances with nutritional effect on the human beings. The leaves stevia contain stevioside, rebaudioside, steviolbioside, isosteviol sweeter than sucrose zero calories. These steviol glycosides considered for sweet taste have comme...

The effects of gamma radiation are investigated by studying seed germination, survival rate and morphological characteristics Stevia rebaudiana. Improvement stevia plant through mutagenesis could be one the ways to produce with delay flowering.
