基于射干鲜药材的产地初加工工艺研究△

目的：研究不同干燥方式对射干有效成分含量的影响，确定最佳干燥方式，为建立射干鲜药材的产地初加工工艺提供依据。方法：采用HPLC法测定射干中次野鸢尾黄素的含量，对采收期的射干鲜药材进行晒干、阴干、55℃、85℃、105℃烘干5种干燥方式处理，比较不同干燥方式对指标成分含量的影响，确定射干最佳初加工工艺。结果：晒干、阴干样品中有效成分含量较鲜药材有所下降，晒干样品含量降低了27％，阴干样品含量降低了9％；三种烘干方式对射干中次野鸢尾黄素含量的影响较小，其中以105℃烘干2h效果为最佳，85℃次之。结论：研究表明105℃烘干2h为射干最佳干燥方式；不同干燥方式对射干中次野鸢尾黄素的含量有较大影响，为最大程度保留鲜药材有效成分及进一步探讨药材指标成分在不同初加工过程中的降解规律提供参考依据。

Study on the Preliminary Processing Technologies Based on Fresh Belamcandae Rhizoma

Objective： To study on the impact of different drying methods on the content of effective compo-nents from Belamcanda chinensis（ L. ） DC. , to determine the best drying methods, and proving a basis for establis-hing the preliminary processing technologies based on fresh Belamcandae rhizoma as well. Methods： HPLC was used to detect the content of irisflorentin from Belamcanda chinensis, and the processing methods including dried in the sun, dried in the shade, dried at 55 ℃, dried at 85 ℃, dried at 105 ℃, were used to determine the best prelimi-nary processing technology, by comparing the content of mark components under different drying methods. Results： Different drying methods have different impacts on the content of irisflorentin. The contents of mark components from the samples that are dried in the sun and dried in the shade have decreased while compared with the fresh herbs, the sample dried in the sun has decreased by 27% and the sample dried in the shade 9% separately. Three stoving meth-ods have less impact on irisflorentin, of which 105 ℃ is the best, 85 ℃ followed. Conclusion： This study showed that the best drying method is drying two hours under 105 ℃. Different drying methods have different impacts to content of irisflorentin. The study provided a basis for retaining the effective components in fresh herbs at the maximum extent, and discussing degradation rule of the mark components in herbs under different preliminary processing.
