射干软化与切制工艺优选

Optimization of Softening and Cutting Process for Belamcanda Rhizoma

目的：对中药射干的软化和切制工艺进行优化。方法：以射干苷、野鸢尾苷、野鸢尾黄素、次野鸢尾黄素、鸢尾黄素和白射干素的含量为指标，采用正交试验的方法对射干软化和切制的工艺进行优化。结果：射干最佳软化和切制工艺为：药材以3倍量的水，浸润24h，切片厚度为1～2mm，并于80℃烘干。结论：优选的射干软化和切制工艺切实可行，可应用于大生产。

Objective ：To optimize softening and cutting technology of Belamcanda rhizoma. Methods ：With the contents of tecto- ridin, iridin, irigenin, irisflorentin, tectorigenin and dichotomitin as indexes, which were determined by HPLC, softening and cutting technology of Belamcanda rhizoma was optimized by orthogonal test. Results ： The optimal processing conditions are as follows ： bel- amcanda rhizoma was immersed in 24 h with three times water at room temperature, cut into 1～ 2 mm piece and drying at 80 ℃. Conclusion ：These optimized process were feasible and could be promoted in industrial production.
