摘　　要：目的:研究半夏的刺激性成分。方法:采用溶剂提取法,X衍射,电镜扫描,氧化还原滴定,紫外分光光度法等。结果:各种实验表明半夏中含有的草酸钙针晶为半夏的刺激性成分之一,其晶形、含量与半夏的刺激性有关。经炮制后,晶形发生变化,含量急剧下降,刺激性明显减弱。Objective:To study the stimulating components of raw Pinellia ternata (Banxia).Methods:Used the methods of extracting with various organic solvents;x ray fluorescence spectrometer;scanning electron microanalyzer;oxidation and reduction titrations;and ultraviolet spectrophotometry.Results:Experiments showed that calcium oxalate hydrate (C 2CaO 4·H 2O) was one of the stimulating components of raw Pinellia ternata, and its shape,and contents related to the stimulation of raw Pinellia ternata .After processing,the shape and contents of calcium oxalate changed,decreased respectively, and the stimulation of Pinellia ternata decreased.Conclusion:The needle crystal of calcium oxalate is one of the stimulating components in raw Pinellia ternata.
