Characterization, Preparation, and Promotion of Plant Growth of 1,3-Diphenylurea/β-Cyclodextrin Derivatives Inclusion Complexes.

ABSTRACT: The study aimed to prepare inclusion complexes of 1,3-diphenylurea (DPU) with β-cyclodextrin (βCD) and 2-hydroxypropyl-β-cyclodextrin (HP-βCD) using a three-dimensional ground mixture (3DGM). Their physicochemical properties, intermolecular interactions, solubilities, and plant growth-promoting activities were investigated on broccoli sprouts. Phase-solubility diagrams indicated the stability constant (K_s) and complexation efficiency (CE) of βCD/DPU were found to be K_1/1 = 250 M^-1, CE = 2.48× 10^-3. The K_s and CEs of HP-βCD/DPU were found to be K_1/1 = 427 M^-1, CE = 3.93 × 10^-3 and K_2/1 = 196 M^-1, CE = 1.93 × 10^-3 respectively. The powder
