Abstract:
Provided are crystalline form A of rebaudioside D, and a preparation method and application therefor. In X-ray powder diffraction analysis measured using Cu-Kα rays and with 2θ being expressed in degrees, crystalline form A of rebaudioside D has significant characteristic diffraction peaks at least at 4.53, 6.38, 12.76, 13.52, 17.48, 17.96, 20.07 and 22.63. The preparation method is a suspension method, a solvent evaporation method or a cooling method. The preparation method has a simple process, and is convenient to operate. A rebaudioside D crystalline form A product has a good degree of crystallinity, good water solubility, and high chemical stability.

Claim (Index 2):
The crystal form A of Rebaudioside D of  claim 1 , wherein the X-ray powder diffraction analysis of the crystal form A obtained using Cu-K\u03b1 ray measurement has characteristic diffraction peaks expressed as 2\u03b8 value in degree with an error range of \u00b11\u00b0, crystal plane spacings expressed as d in \u212b and relative intensity of the diffraction peaks expressed as a percentage, which have the following characteristics: 2 \u03b8 d relative intensity % 4.53 19.5129 39.7 6.38 13.8374 46.4 10.37 8.5210 33.9 12.76 6.9319 54.9 13.52 6.5432 52.0 15.11 5.8596 27.8 16.45 5.3858 25.3 17.48 5.0695 100.0 17.96 4.9363 98.7 18.36 4.8291 21.0 18.64 4.7571 36.2 20.07 4.4197 73.7 20.49 4.3300 39.8 22.63 3.9259 57.0 24.18 3.6775 27.6 24.79 3.5891 23.8 26.19 3.4005 20.7
