目的根据真空蒸汽润药原理,对浙产三棱进行气相置换软化,优化三棱润制工艺。方法采用真空蒸汽润药机优化三棱润制工艺,并与传统润制方法进行比较。采用正交实验对润药工艺进行多因素考察,运用紫外分光光度法测定总黄酮的含量,以三棱醇浸出物和总黄酮的含量为综合评价指标,筛选最佳优化方案。结果采用真空蒸汽润药软化后的三棱饮片含水量低,软化效果好,浸出物和总黄酮含量高。结论真空蒸汽润药法可使药材在低含水量的情况下,快速、均匀地软化,还可提高三棱中有效成分的含量。
Objective According to the principle of vacuum steaming medicine, gas-phase substitution and softening of Triangle of Zhejiang Trials was carried out to optimize the trigeminy process. Methods The steam spraying machine was used to optimize the trigeminy process, and compared with the traditional method. The orthogonal experiment was used to investigate the multi-factors of the process of the lotion. The content of total flavonoids was determined by ultraviolet spectrophotometry. The content of trimeric alcohol extract and total flavonoids was used as the comprehensive evaluation index, and the best optimization scheme was screened. Results The results showed that the low-moisture content, softening effect and high content of extract and total flavonoids in the three-rowed pieces softened by vacuum steam moid. Conclusion The vacuum steaming method can make the medicinal materials soften rapidly and uniformly under the conditions of low water content, and can also increase the content of active ingredients in the three edges.
