主　　题：calcium carbonate crystal growth microsphere vegetable X-ray diffraction 

摘      要：We report a novel strategy for the green synthesis of calcium carbonate （CaCO3） microspheres by using four vegetables： potato, cucumber, aubergine, and carrot. The products were characterized by scanning electron microscopy, X-ray powder diffractometry and/or Fourier transform infrared spectroscopy. The results show that the spherical calcite crystals are obtained in the presence of potato, cucumber and aubergine extracts, while uniform vaterite and calcite mixed microspheres are produced with the extracts of carrot. The possible formation mechanism of the CaCO3 microspheres by using vegetables is also discussed, suggesting that the biomolecules especially proteins may induce and control the nucleation and growth of CaCO3 crystals. CaCO3 is an important biomineral and inorganic material. Uniform particles have numerous important applications in many areas. Therefore, this study is very significant not only for expanding the scope of crystal engineering, but also for biomineralization research and green synthesis of functional inorganic materials.
