The inclusion complex of beta-cyclodextrin with gossypol was synthesized by using a convenient method of microwave irradiation. The structure of the complex was determined by 1H NMR, IR spectroscopy, and as well as the elemental analysis; the thermal stability was studied by means of differential thermal analysis (DTA) and thermogravimetric analysis (TGA). The association constant between gossypol and beta-cyclodextrin measured via UV spectroscopy was 4462M(-1) at room temperature, following stoichiometry 1:2.
采用简便的微波辐射法合成了β-环糊精与棉酚的包合物。通过1H NMR、红外光谱以及元素分析确定了包合物的结构；借助差示热分析（DTA）和热重分析（TGA）研究了其热稳定性。通过紫外光谱测得棉酚与β-环糊精在室温下的缔合常数为4462M(-1)，化学计量比为1:2。
