The most important characteristic of stevia is its high sweetness with zero calories which is due to the presence of Steviol glycosides (SVglys). This research aims to address the effect of salicylic acid (SA) and microelements viz. iron (Fe) and zinc (Zn) under different soil water potentials (-0.5, -3.5, -6.5 and -10 atm) on the production of SVglys and total sugar content in the leaves o...

Arthrobacter sp. 10137 has been used to produce b-fructofuranosidase (FFase). Sucrose and corn steep powder in an optimized ratio of 10:1 were the best carbon and nitrogen sources for enzyme production in a shake flask. The maximum FFase activity was 26.69 U/mL after 22.5 h in batch culture, and the crude FFase, obtained by ultrafiltration and (NH4)2SO4 fractionation, was purified about 7-fold ...

Catalytic hydrogenation of the three ent-kaurane diterpene glycosides isolated from Stevia rebaudiana, namely rubusoside, stevioside, and rebaudioside-A has been carried out using Pd(OH)₂ and their corresponding dihydro derivatives have been isolated as the products. Synthesis of reduced steviol glycosides was performed using straightforward chemistry and their structures were characterized on ...

Glucagon like peptide-1 (GLP-1) and serotonin are both involved in food intake regulation. GLP-1 release is stimulated upon nutrient interaction with G-protein coupled receptors by enteroendocrine cells (EEC), whereas serotonin is released from enterochromaffin cells (ECC). The central hypothesis for the current study was that nutrient-induced GLP-1 release from EECs is modulated by serotonin t...

Stevia rebaudiana, a perennial herb from the Asteraceae family, is known to the scientific world for its sweetness and steviol glycosides (SGs). SGs are the secondary metabolites responsible for the sweetness of Stevia. They are synthesized by SG biosynthesis pathway operating in the leaves. Most of the genes encoding the enzymes of this pathway have been cloned and characterized from Stevia. O...

The aim of this study was to analyze the optimum temperature and percentage ethanol extract steviol glycosides (Stevioside Rebaudioside A) from stevia leaves in a percolation extractor. experiments were performed broad ranges binary solvent (0-100 % ethanol) (30–70 °C) order investigate their effects on recovery purity. optimal extraction conditions, which gave best kinetic 70 °C 35% ethanol. I...
