The Germplasm Bank of Stevia rebaudiana segregants the University Córdoba is a strategy for use genetic variability and efficient crop yield. There are genotypes with important characteristics such as: high tolerance to salt stress climatic change (high CO2 in Earth surface), late flowering, erect architecture, contents steviol glycosides. However, there lack in-depth studies morphophysiologica...

To evaluate and characterize stevioside biosynthetic pathway in Stevia rebaudiana Bertoni cv Houten, two enzyme fractions that catalyze glucosylation of steviol (ent-13-hydroxy kaur-16-en-19-oic acid) and steviol-glucosides (steviol-13-O-glucopyranoside, steviolbioside and stevioside), utilizing UDP-glucose as the glucose donor, were prepared from the soluble extracts of S. rebaudiana leaves. E...

Several studies have demonstrated that tea flavonoids protect cells and tissues against free radicals which have been implicated in the etiology of oxidative stress-related disease disorders. However, black tea is commonly consumed with additives that could otherwise affect the bioavailability of the active tea molecules. In this study, the biochemical parameters of Kenyan teas were determined ...

Extracts of leaves of the plant Stevia rebaudiana Bertoni (SrB), have been used for many years in traditional treatment of diabetes in South America. Stevia leaves contain diterpene glycosides, stevioside and rebaudioside A being the most abundant. Recently, it was demonstrated that stevioside stimulates the insulin secretion both in vitro and in vivo. Subsequently, we wanted to elucidate the i...

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...

L Objective: Stevia rebaudiana Bertoni is a crop that can meet the demand for natural sweeteners; however, this requires sustainable production, as result of inclusion its steviol glycosides or active ingredients in food and pharmaceutical industries. Design/methodology/approach: Modern agriculture implies integrated use valid resources, such arbuscular mycorrhizal fungi (AMF). These microorgan...

BACKGROUND Stevia rebaudiana regulates blood sugar, prevents hypertension and tooth decay. Other studies have shown that it has antibacterial as well as antiviral property. METHODS Preliminary phytochemical screening of aqueous, ether and methanolic extracts of S. rebaudiana was done. Acute and sub-acute toxicity were conducted on twenty four Albino rats, divided into one control (Group I) an...
