To evaluate the free radical scavenging activity of flavonoids containing extracts of Stevia leaf. Alcoholic. Successive butanolic and alcoholic extracts of leaves were examined for free radical scavenging activity using BHT (tert-butylhydroxytolune) as a positive control by in vitro models. Successive alcoholic extract showed remarkable free radical scavenging activity. The IC(50) was found to...

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...

This study was conducted to compare the effects of foliar spray and rhizosphere irrigation with purple phototrophic bacteria (PPB) on growth and stevioside (ST) yield of Stevia. rebaudiana. The S. rebaudiana plants were treated by foliar spray, rhizosphere irrigation, and spray plus irrigation with PPB for 10 days, respectively. All treatments enhanced growth of S. rebaudiana, and the foliar me...

Stevia rebaudiana (Bert.) Bertoni, commonly called “sweet leaf” is a medicinally and industrially important plant known to be rich in zero-calorie natural sweetening compound(s) as “steviol glycosides”. However, due its poor seed germination slow vegetative propagation, it has become rather difficult meet the increasing global demand for Stevia-based products. Different biotechnological approac...

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...

Stevia leaves contain glycosides on which biological activity and sweetening capacity has been reported. Besides the main glycosides—stevioside and rebaudioside A—there are minor glycosides that may contribute to the activity and thus it is important to quantify them. Rebaudioside D is one of the minor glycoside present in S. rebaudiana leaves and there are no reports of a validated method to q...

The aim of the presented study was to characterize the content and biological activity of extracts prepared from dried Stevia rebaudiana leaves with potential application in the food or cosmetic industry. Aqueous (A), ethanolic (E) and glycol-aqueous (GA) extracts were analyzed for the content of polyphenols and proteins, showing that the highest amount of phenols (15.50 mg/g) and flavonoids (3...
