Steviosid aus Süßkraut

Chemie in unserer Zeit, 2016
AbstractDas Diterpenglykosid Steviosid ist das häufigste in einer Gruppe süß schmeckender Steviolglykoside, die im Süßkraut (Stevia rebaudiana) vorkommen. Es stammt aus Paraguay und wurde bereits von den Guarani‐Indianern genutzt. 2011 EU‐weit als Lebensmittelzusatzstoff E 960 (Süßstoff) zugelassen, schmecken diese Naturstoffe etwa 250mal süßer als ...

The effect of stevioside on glucose metabolism in rat

Canadian Journal of Physiology and Pharmacology, 1997
This study was conducted to determine the effect of stevioside (SVS) on glucose metabolism. The experiments were performed in male Wistar rats treated with SVS either by intravenous infusion or feeding. SVS infusion (150 mg/mL) was carried out in doses of 0.67, 1.00, and 1.33 mL.kg-1 body weight.h-1.

Measurement of Stevioside by Square‐Wave Polarography

Electroanalysis, 2010
AbstractSteviol glycosides are electroactive compounds and can be detected by mercury electrode. The maxima of square‐wave polarograms of steviol and stevioside appear at −1.3 V vs. Ag/AgCl in 1 M NaCl at approximately pH 11. The responses are quasireversible and probably caused by electroreduction of carboxyl, or ester groups, respectively.

Hydrolysis of the diterpenoid glycoside, stevioside

Phytochemistry, 1990
Abstract The minor products from the acid-catalysed hydrolysis of the diterpenoid glycoside, stevioside have been identified and the location of the deuterium has been established when the hydrolysis is carried out in the presence of deuterium bromide.

Syntheses of (−)-Tripterifordin and (−)-Neotripterifordin from Stevioside

The Journal of Organic Chemistry, 2018
We report short syntheses of (-)-tripterifordin and (-)-neotripterifordin, potent inhibitors of HIV replication, from stevioside, a natural sweetener used worldwide. The key transformations are reduction at C13 through the formation of a tertiary chloride and subsequent three-step lactonization including a selective iodination at C20 by the ...

Assessment of the carcinogenicity of stevioside in F344 rats

Food and Chemical Toxicology, 1997
The carcinogenic potential of stevioside, a compound that is used as a sweetener for food and drink, was examined in F344 rats of both sexes. Stevioside was added to powdered diet at concentrations of 0 (control), 2.5 and 5%. The doses were selected on the basis of results from a 13-wk subchronic toxicity study and administered to groups of 50 male and

Development of Antidiabetic Nanomedicine from Stevioside

Journal of Biomedical Nanotechnology, 2011
Stevioside, a non-caloric sweetener has huge therapeutic potential as an antidiabetic biomolecule. Stevioside nano-bioconjugated on PEG-PLA nanoparticles of size 150-170 nm showed the initial burst phase followed by the slow controlled release of 2 h and 21 days respectively.

Renal Excretion of Stevioside in Rats

Journal of Natural Products, 1992
The renal excretion of stevioside, a glycoside extracted from the leaves of Stevia rebaudiana, and its effect on renal excretion of several substances, was studied through clearance techniques in Wistar rats. After a control period, stevioside was infused iv at four concentrations (4, 8, 12, and 16 mg/kg).

Pharmacokinetic studies of 131I-Stevioside and its metabolites

Nuclear Medicine and Biology, 1996
131I-STEVIOSIDE (1.10 MBq) was injected i.v in Wistar male rats, in distribution in the body and metabolism were studied. The highest concentration of radioactivity was observed in the liver and in the small intestine after 10 and 120 minutes, respectively. At 2 h after injection, the radioactivity eliminated in the bile was 52.0% of the original dose.
