Comparision of Physical Characteristics of Submicron Powder and Common Powder of Dendrobium officinale
To compare the physical properties between the submicron powder and common powder, we have done the research on the angle of repose, slip angle, solubility, soakage, dispersibility and the microscopic structure.The result is that the physical properties of submicron powder is better than those of the common powder's, not only the the angle of repose, slip angle, but also in the solubility, soakage, dispersibility, etc. The microscopic structure by standard light microscopes and scanning electron microscope shows that submicron powder of Dendrobium officinale has bigger broken of its plant cell, and higher bioavailability, which will make greater market outlook.
