摘要：苯甲基異硫氰酸酯不穩(wěn)定，通過β-環(huán)糊精包合技術(shù)形成包合物后，可提高該物質(zhì)的穩(wěn)定性。本實驗確定了β-環(huán)糊精-苯甲基異硫氰酸酯包合物的定量分析方法。并采用響應(yīng)曲面法，優(yōu)化了苯甲基異硫氰酸酯的包合工藝。分析了各因素的顯著性和交互作用。結(jié)果表明：β-環(huán)糊精-苯甲基異硫氰酸酯包合物制備的最佳包埋條件為：β－環(huán)糊精：BITC（g：mg）為0.174，包合溫度為55.320C，在最佳包埋條件下的包埋率為96.09%。本方法包合成本低，工藝簡便，具有一定的實用價值。

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.
