Insights Into the Properties of Amygdalin Solvatomorphs : X-ray Structures, Intermolecular Interactions, and Transformations
© 2022 The Authors. Published by American Chemical Society..
Amygdalin is an effective component of the traditional Chinese medicine bitter almond, peach kernel, and plum kernel. It has pharmacological effects, such as relieving cough and asthma. In a study of the crystallization process, we found a series of solvatomorphs of amygdalin (including hydrate). Interestingly, in the structures of these solvatomorphs, the same characteristic structural fragment is present, that is, amygdalin dihydrate. Multiple analytical techniques were used to characterize the solvatomorphs, such as X-ray diffraction and thermogravimetry-mass spectrometry. Void calculations of water and solvent were used to analyze the occupied volume in the unit cell of the corresponding solvatomorphs to explain the formation mechanism of the solvatomorphs from the perspective of space. To elucidate the formation mechanism of the solvatomorphs with this kind of characteristic structure from the perspective of energy, theoretical calculations based on density functional theory were applied, such as energy decomposition and molecular electrostatic potential surfaces. In addition, the transformation phenomenon between these solvatomorphs and amygdalin was identified, and the transformation pathways are described in detail.
