【摘要】 目的:考查不同加工方法对半夏品质的影响。方法:采用气相色谱法对不同方法干燥的半夏样品中的甾醇类成分进行分析测试。结果:经70℃烘2h再以低温烘干或低温反复干燥的半夏样品,其5个特有的甾醇类成分的指纹特征峰非常稳定,且每个样品色谱特征的相似度很高。而未经适当高温处理、或低温干燥未干透的半夏样品,其所含甾醇类成分的色谱峰均不同程度降低,有些甚至难以检出。结论:半夏采收后适当采用高温处理(例如70℃,2h),再低温充分干燥,有利于半夏中甾醇类成分的保存和稳定。更多还原

【Abstract】 Objective:Investigate the effect of different processing methods on the quality of Rhizoma Pinelliae. Methods:The sterol compounds from different Rhizoma Pinelliae samples processed with different drying methods were analysed by GC.Results:The fingerprints of five specific steroid components are very stable in those samples of Rhizoma Pinelliae which first dried 2h at 70℃then baked at low temperature or by repeated low-temperature,and the the five peaks from each sample have high similarity.But the samples dried without a proper treatment at higher temperature or with a halfway dryness at low-temperature showed a reduced peak height of steroid,to varying degrees and some were hardly detected.Conclusion:It is conducive to the preservation and stability of stroids of Pinellia ternata that to being Dried at proper high temperature such as at 70℃for 2h first then fully dried at low temperature.更多还原
