General description

Componentof stevia.
Rebaudioside D, a glycoside of the diterpene steviol is a minor constituent found in leaves of Stevia rebaudiana. It is considered non-caloric and is about 200–220 times sweeter than sucrose.

Application

It may be used as internal standard to optimize the desorption electrospray ionization (DESI) mass spectrometry during the analysis of Stevia leaves for diterpene glycosides.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

The Analyst, 134(5), 867-874 (2009-04-22)
The analysis of Stevia leaves has been demonstrated without any sample preparation using desorption electrospray ionization (DESI) mass spectrometry. Direct rapid analysis was achieved using minimal amounts of sample ( approximately 0.15 cm x 0.15 cm leaf fragment). Characteristic constituents

Catalytic hydrogenation of rebaudioside B, rebaudioside C, and rebaudioside D; the three ent-kaurane diterpene glycosides isolated from Stevia rebaudiana was carried out using Pd(OH)(2). Reduction of steviol glycosides was performed using straightforward synthetic chemistry with the catalyst Pd(OH)(2) and structures
