目的 探讨炮制饮片色泽评价方法,定量分析饮片色泽与饮片内在质量之间的关系。方法 以泽泻不同炮制工艺为研究对象,用照相机和Adobe Photoshop软件,获取各饮片色泽的基本信息,用HPLC法测定饮片的有效成分。用SPSS13.0统计软件和数据挖掘软件Clementine8.0对色泽信息和有效成分量的关系进行分析。结果 饮片色泽信息获取方法和信息处理方法可定量评价炮制饮片的色泽、饮片色度差与有效成分之间存在显著相关。结论 饮片色度差可以作为饮片质量评判标准的指标之一,并易于推广。

Objective To investigate the evaluation method of processing pieces' colour and quantificationally analyse the relactionship between the pieces' colour and the internal quality.Methods Taking different processing techniques on Rhizoma Alismatis as research objects,using a camera and Adobe Photoshop software to acquire the elementary information of processing pieces' colour and determine the contents of the active principle in Rhizoma Alismatis by HPLC.The active principle in Rhizoma Alismatis and the colour of processing pieces are analyzed quantificationally by SPSS 13.0 statistical softw are and data mining software Clementine 8.0.Results The method for acquiring and handling colour information of processing pieces in Rhizoma Alismatis could be used to quantificationally analyze the correlation of the colour of processing pieces.There is a significant correlation between processing pieces colour difference and the internal quality Conclusion The colour difference of processing pieces can be one of target for the quality assessment.The method can be popularized to other precessing pieces control of techniques.
