摘要：苯甲基异硫氰酸酯不稳定，通过β-环糊精包合技术形成包合物后，可提高该物质的稳定性。本实验确定了β-环糊精-苯甲基异硫氰酸酯包合物的定量分析方法。并采用响应曲面法，优化了苯甲基异硫氰酸酯的包合工艺。分析了各因素的显著性和交互作用。结果表明：β-环糊精-苯甲基异硫氰酸酯包合物制备的最佳包埋条件为：β－环糊精：BITC（g：mg）为0.174，包合温度为55.320C，在最佳包埋条件下的包埋率为96.09%。本方法包合成本低，工艺简便，具有一定的实用价值。

Abstract: Benzylisothiocyanate is unstable as aromatic sulfur-containing active compounds. It could be embedded into β-cyclodextrin in order to improve its stability by the β-cyclodextrin inclusion technology. In this experiment, the quantitative analysis method of β-cyclodextrin - benzyl isothiocyanate complex was studied. In order to improve the inclusion ratio, response surface central composite design pattern was used. The inclusion parameters was optimized and variance analysis was conducted. The results showed that the best embedding conditions to prepare the β-cyclodextrin - benzyl isothiocyanate inclusion complexes:β-cyclodextrin: BITC (g:mg) is 0.174, inclusion temperature is 55.320C, in this optimum conditions, the inclusion ratio is 96.09%. The developed inclusion process has the advantages of low cost, simplicity, thereby providing a promising approach for the prolongation of the stability of benzyl isothiocyanate.
