目的 研究半夏Pinelliae Rhizoma产地加工去皮前的处理方法及工艺参数，为保证半夏药材质量提供关键的技术参数。方法 分别采用“自然发汗”“拌石灰粉”“拌石灰水”3种方法处理，在各法处理第2、4、6、8天取样、去皮。以样品外观性状、叶绿素含量、去皮率、得率、浸出物和琥珀酸含量为指标进行综合评价。结果 以样品性状及叶绿素含量为指标评价时，半夏质量以拌石灰水法为最佳，其次为拌石灰粉；以样品去皮率、得率及浸出物和琥珀酸含量为评价指标时，以拌石灰粉处理4 d的样品较好。按总评归一法综合评分，确定拌石灰粉处理4 d为最佳处理方法。结论 半夏产地加工去皮前以拌石灰粉（每100 kg鲜半夏用石灰为10 kg）处理4 d为最佳，该方法简便，药材质量好。

Objective To study the process parameters and pre-peeling method before field processing of Pinelliae Rhizoma, and to guarantee key technical parameter for the quality of Pinelliae Rhizoma. Methods Three methods of “natural sweating”, “mixing lime powder” and “mixing lime water” were used. Samples were taken away and peel on the 2nd, 4th, 6th, and 8th d of each method. Macrocosmic evaluation was performed by using the sample appearance characteristics, determination of chlorophyll content, peeling rate and yield rate, extractum and succinic acid contents as indicators. Results When evaluating indicator based on sample properties and chlorophyll content, the method of mixing lime water was the best, followed by the mixing of lime powder; When evaluating indicator based on the sample peeling rate, yield rate, and extractum and succinic acid content, the samples treated with mixing lime powder for 4 d were best. According to the total evaluation and normalization method of comprehensive score, the best processing method was mixing the lime powder for 4 d. Conclusion Pinelliae Rhizonma before processing and peeling is treated with lime powder (10 kg of lime per 100 kg of fresh Pinelliae Rhizoma) for 4 d for the best. The method is simple and the quality is pretty good.
