Description
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.Rebaudioside D is a natural non-caloric sweetener. It is a steviol glycoside that has been found in S. rebaudiana leaves. Rebaudioside D, similarly to rebaudioside A and rebaudioside C, is metabolized by gut microbiota to steviol, a compound whose safety is widely studied.
Uses
Rebaudioside D is a steviol glycoside used as a nutritive sweetener and may be used as a replacement for sugar in foods and beverages. Useful in the treatment of blood glucose sensitive diseases such as diabetes, high blood pressure, and obesity.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.
Preparation
The rebaudioside D-rich steviol glycoside preparation (~95% rebaudioside D) is produced via an enzymatic conversion process using a strain of Pichia pastoris that has been genetically modified to express UDPglucosyltransferase EUGTll. In the first stage of manufacturing, a steviol glycoside primary extract from the leaves of 5. rebaudiana Bertoni containing 55±5% of rebaudioside A is produced according to the methodology outlined in the Chemical and Technical Assessment (CTA) published by the Food and Agriculture Organization (FAO)/JECFA for steviol glycosides (FAQ, 2016). In the next step, the steviol glycoside primary extract is further purified to a purity of ~95% rebaudioside A through crystallization, also consistent with the CTA methodology. In the third stage, the P. pastoris production strain is subjected to a fermentation step to express the UGT-glucosyltransferase EUGTll, which is used to catalyze the conversion of the high-purity rebaudioside A extracted from 5. rebaudiana Bertoni to rebaudioside D. In the last stage, the rebaudioside D solution is purified and concentrated according to the methodology described in the steviol glycoside CTA, yielding a final product that contains ~95% rebaudioside D.www.fda.gov
Check Digit Verification of cas no
The CAS Registry Mumber 63279-13-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,2,7 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 63279-13:
(7*6)+(6*3)+(5*2)+(4*7)+(3*9)+(2*1)+(1*3)=130
130 % 10 = 0
So 63279-13-0 is a valid CAS Registry Number.

Diversity-Oriented Synthesis of Steviol Glycosides

With cheap and easily available mixtures of steviol glycosides as starting materials, a practical method for steviol acquisition has been developed, on the basis of which a facile, diversity-oriented, and economic protocol for the synthesis of structurally defined steviol glycosides was established. The novel approach is featured by the highly efficient glycosylation of sterically hindered and acid-sensitive steviol via orchestrated application of Yu glycosylation, Schmidt glycosylation, and PTC glycosylation. Hence, these high-intensity sweeteners and potential lead compounds for drug development are now readily accessible.
HIGH-PURITY STEVIOL GLYCOSIDES

, (2016/04/09)
Methods of preparing highly purified steviol glycosides, particularly rebaudiosides A, D and M are described. The methods include utilizing recombinant microorganisms for converting various staring compositions to target steviol glycosides. In addition, novel steviol glycosides reb D2, reb M2, and reb I are disclosed, as are methods of preparing the same. The highly purified rebaudiosides are useful as non-caloric sweetener in edible and chewable compositions such as any beverages, confectioneries, bakery products, cookies, and chewing gums.
RECOMBINANT PRODUCTION OF STEVIOL GLYCOSIDES
-
Paragraph 0054; 0360; 0361, (2016/08/17)
Recombinant microorganisms, plants, and plant cells are disclosed that have been engineered to express recombinant genes encoding UDP-glycosyltransferases (UGTs). Such microorganisms, plants, or plant cells can produce steviol glycosides, e.g., Rebaudioside A and/or Rebaudioside D, which can be used as natural sweeteners in food products and dietary supplements.
