| 摘要: |
| 目的 基于粉末颜色数字化建立鉴别真伪降香数学模型的判别分析。方法 收集39批市售降香样品，使用色差仪测量降香粉末L*、a*、b*、E*ab值，运用显微和薄层方法鉴别市售降香真伪，通过统计学分析，建立市售降香真、伪判别分析模型。结果 通过测定市售降香粉末色差值，建立市售降香真、伪色差判别数学模型，判别真伪结果与鉴别结果一致。结论 通过色差值快速鉴别真伪降香的方法有效，可以为中药材色差鉴别和分析提供参考和依据。 |

| Abstract: |
| OBJECTIVE To establish a discriminant analysis of a mathematical model for distinguishing genuine and fake Dalbergiae Odoriferae Lignum based on the digitization of powder color. METHODS The 39 samples of Dalbergiae Odoriferae Lignum sold in the market were collected, and the L*,a*, b*, E*ab values of Dalbergiae Odoriferae Lignum powder were measured by using a color difference meter, and the authenticity of the Dalbergiae Odoriferae Lignum sold in the market was identified by using microscopic and thin layer methods, and a discriminant analysis model for the authenticity of Dalbergiae Odoriferae Lignum was established through statistical analysis. RESULTS A mathematical model for distinguishing true and false color difference of Dalbergiae Odoriferae Lignum was established by measuring the color difference value of Dalbergiae Odoriferae Lignum powder in the market. The results of distinguishing authenticity and falsehood were consistent with those of ordinary discrimination. CONCLUSION The method of rapid identification of true and false Dalbergiae Odoriferae Lignum by color difference value is effective, which can provide reference and basis for color difference identification and analysis of Chinese herbal medicines. |
