Aim To study the physicochemical properties of Venenum Bufonis beta-cyclodextrin (β-CD) inclusion complex.Methods The inclusion complex was identified by the methods of TLC,X-ray powder diffractometry and infrared spectroscopy (IR).The solubility and dissolution rate of bufadienolide of inclusion complex were investigated by UV.Results The results of TLC showed that the main composition of Venenum Bufonis had no change before and after being included by β- CD.The spectrum of IR and X-ray powder diffractomet...
