T. Chen is traditionally referred to as "Dalbergiae Odoriferae Lignum" in traditional Chinese medicine. Its quality is typically assessed subjectively based on colour and texture observations and lacks a universal grading system. Our objective was to establish a relationship between heartwood colour and the content of key constituents, including total flavonoids, six specific flavonoids, alcohol-soluble extracts, and volatile oils, to assess their impact on heartwood quality. Substantial correlations were observed between the colour depth (), red-green direction (), and yellow-blue direction (), as well as the content of the extract, volatile oil, total flavonoids, naringenin, formononetin, pinocembrin, and isoliquiritigenin. Specifically, was correlated with the extract, total flavonoids, and isoliquiritigenin, whereas was correlated with the extract, volatile oil, total flavonoids, naringenin, formononetin, pinocembrin, and isoliquiritigenin. The results suggested that , , and chemical composition indices, such as extract, volatile oil, total flavonoids, and naringenin, could serve as primary criteria for classifying the quality of medicinal materials. This is consistent with market classification based on colour and texture, which facilitates material identification and guides the cultivation, harvesting, and processing of This study provides a scientific foundation for its future development and use.
在中药中，T. Chen 传统上被称为“降香黄檀”。其质量通常是通过颜色和纹理观察进行主观评估，缺乏通用的分级系统。我们的目标是建立心材颜色与关键成分含量之间的关系，包括总黄酮、六种特定黄酮、醇溶性提取物和挥发油，以评估它们对心材质量的影响。颜色深度（）、红-绿方向（）和黄-蓝方向（）与提取物、挥发油、总黄酮、柚皮苷、芒柄花素、松属素和甘草素含量之间存在显著相关性。具体而言，与提取物、总黄酮和甘草素含量呈正相关，而与提取物、挥发油、总黄酮、柚皮苷、芒柄花素、松属素和甘草素含量呈正相关。结果表明，颜色、化学组成指数（如提取物、挥发油、总黄酮和柚皮苷）可作为分类药材质量的主要标准。这与基于颜色和纹理的市场分类一致，有助于材料鉴定，并指导 的种植、收获和加工。本研究为其未来的开发和利用提供了科学依据。
