Syntheses of (−)-Tripterifordin and (−)-Neotripterifordin from Stevioside
The Journal of Organic Chemistry, 2018We 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 ...

Effect of stevioside on growth and reproduction*
Human Reproduction, 1991The 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 ...

Stevioside and related compounds: Therapeutic benefits beyond sweetness
Pharmacology & Therapeutics, 2009Stevioside, an abundant component of Stevia rebaudiana leaf, has become well-known for its intense sweetness (250-300 times sweeter than sucrose) and is used as a non-caloric sweetener in several countries. A number of studies have suggested that, beside sweetness, stevioside along with related compounds, which include rebaudioside A (second most ...

Hydrolysis of the diterpenoid glycoside, stevioside
Phytochemistry, 1990Abstract 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.

Renal Excretion of Stevioside in Rats
Journal of Natural Products, 1992The 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).

Photostability of Rebaudioside A and Stevioside in Beverages
Journal of Agricultural and Food Chemistry, 2008The 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,

Pharmacokinetic studies of 131I-Stevioside and its metabolites
Nuclear Medicine and Biology, 1996131I-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.

Development of pure certified reference material of stevioside
Food Chemistry, 2018Pure stevioside was extracted from leaves of Stevia rebaudiana (Bertoni) to be used as a reference material in the instrument calibration or method validation process. The mass fraction was determined by comparison between the mass balance method and quantitative nuclear magnetic resonance (qNMR) spectroscopy. The impurities in the sample were analyzed
