Evaluation of Steviol Injection on Chicken Embryos: Effects on Post-hatch Development, Proportional Organ Weights, Plasma Thyroid Hormones and Metabolites

Autor: Mohsen Daneshyar, Jan M.C. Geuns, Johan G. Buyse, Hassan Kermanshahi, Hilke Willemsen, Zarbakht Ansari, Eddy Decuypere, Nadia Everaert

Publikováno v: The Journal of Poultry Science, Vol 47, Iss 1, Pp 71-76 (2010)

At day 7 of incubation, eggs were injected with high levels of steviol (1.5 and 3mg per egg). At hatch, no effect of steviol injection was observed on plasma thyroid hormone levels, hatchability, body weight and chick quality. Proportional liver weig

Degradation of steviol glycosides via steviol and Monicanone by soil microorganisms and UASB effluent

Autor: Etienne Jooken, Nico Moons, Annick Monballiu, Gert Steurs, Jan M.C. Geuns, Boudewijn Meesschaert, Ruis Amery

Steviol glycosides are fully deglycosylated to steviol in the presence of bacterial populations that were isolated from different soil samples. Heating (20 min at 80 °C) or boiling (10 min at 100 °C) of soils had little effect on the steviol format

Steviol glycosides correlation to genes transcription revealed in gibberellin and paclobutrazol-treated Stevia rebaudiana

Autor: Shokoofeh Hajihashemi, Jan M.C. Geuns

Publikováno v: Journal of Plant Biochemistry and Biotechnology. 26:387-394

Stevia rebaudiana contains steviol glycosides (SVglys) responsible for its sweet taste. The knowledge of some shared steps between gibberellin (GA) and SVglys biosynthesis made it imperative to study the effect of paclobutrazol (PBZ; a GA biosynthesi

Gene transcription and steviol glycoside accumulation in Stevia rebaudiana under polyethylene glycol‐induced drought stress in greenhouse cultivation

Autor: Shokoofeh Hajihashemi, Jan M.C. Geuns

Publikováno v: FEBS Open Bio

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/

Validation of an HPLC method for direct measurement of steviol equivalents in foods

Autor: Uria Bartholomees, Tom Struyf, Olivier Lauwers, Jan M.C. Geuns, Stijn Ceunen

Publikováno v: Food Chemistry. 190:270-275

Steviol glycosides are intense natural sweeteners used in foods and beverages. Their acceptable daily intake, expressed as steviol equivalents, is set at 0-4 mg/kg body weight. We report the development and validation of a RP-HPLC method with fluorom

Synthesis of an IS and Steviol Glycoside Analysis by a Validated Internal Standard Method

Autor: Tom Struyf, Stijn Ceunen, Wim M. De Borggraeve, Gert Steurs, Jan M.C. Geuns

The internal standard (IS) method is the best method for the analysis of samples, as it is independent of errors in injection volume, changes in sample volumes, and changes in sensitivity of the detector, etc. Use of an internal standard allows for t

Autor: Jan M.C. Geuns, Stijn Ceunen

Publikováno v: Biologia plantarum. 57:390-394

The amount of free glucose and sucrose within the leaves of Stevia rebaudiana has been evaluated under different photoperiods and related to steviol glycoside (SVgly) accumulation. The diurnal dynamics of glucose and sucrose in leaves, internodes, ap
