Metabolism of Stevioside by Chickens

Journal of Agricultural and Food Chemistry, 2003
In intubation experiments (643-1168 mg per animal), most of the stevioside administered to chickens was recovered unchanged in the excreta, and only about 2% was converted into steviol. Neither stevioside nor steviol could be found in the blood. In chronic studies (667 mg of stevioside/kg of feed) with laying hens and meat-type chickens, no significant

Metabolism of stevioside in pigs and intestinal absorption characteristics of stevioside, rebaudioside A and steviol

Food and Chemical Toxicology, 2003
Stevioside orally administered to pigs was completely converted into steviol by the bacteria of the colon. However, no stevioside or steviol could be detected in the blood of the animals, even not after converting steviol into the (7-methoxycoumarin-4-yl)methyl ester of steviol, a very sensitive fluorescent derivative with a detection limit of about 50

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.

Effect of stevioside on growth and reproduction*

Human Reproduction, 1991
The effect on growth and reproduction in hamsters of stevioside, which is extracted from stevia leaves (Stevia rebaudiana Bertoni) and is currently used as a non-caloric sweetener, was investigated. Four groups of 20 one-month-old hamsters (10 males and 10 females) were daily force-fed with stevioside (0.0, 0.5, 1.0 and 2.5 g/kg body wt/day ...

Photostability of Rebaudioside A and Stevioside in Beverages

Journal of Agricultural and Food Chemistry, 2008
The Coca-Cola Company and Cargill, Inc. have initiated the development and commercialization of the Stevia rebaudiana (Bertoni) derived sweetener rebaudioside A. Efforts were focused on high purity rebaudioside A (>97% by HPLC), commonly known as rebiana. In the course of the development program, extensive stability studies were carried out on rebiana,

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.

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 ...
