摘　　要：目的:探讨泽泻炮制饮片的质量控制指标可行性。方法:采用高效液相色谱法测定泽泻饮片中24-乙酰泽泻醇A和23-乙酰泽泻醇B的含量;采用照相机和Adobe Photoshop软件获取饮片外观信息,评判不同产地泽泻炮制饮片的色泽差异。结果:各炮制饮片中24-乙酰泽泻醇A和23-乙酰泽泻醇B总量均大于0.08%,泽泻饮片色泽均匀性在10～2.5,泽泻饮片色度差在2～8个色度单位。结论:所选质控指标可反映泽泻饮片的内在质量,可用于中药泽泻的质量控制。Objective： To explore the feasibility of quality control index of processed alisma pieces.Method：The content of 24-acetyl alisol A and 23-acetyl alisol B in processed alisma pieces was determined by high performance liquid chromatography;appearance information of processed pieces was gotten by cameras and Adobe Photoshop software,to evaluate the shade diferential of different origin.Result：The total amount of 24-acetyl alisol A and 23-acetyl alisol B in every processed alisma were more than 0.08%.Color uniformity of processed alisma was between 10 to 2.5,and the processed alisma chromatic diferential was in the 2-8 chromatic units.Conclution：The quality control indicators to reflect the intrinsic quality of processed Alisma Pieces can be used for quality control of traditional Chinese medicine alisma.
