本研究旨在鉴定降香黄檀心材提取物中的黄酮类化学成分，探讨其与心材色泽的相关性，为建立心材质量的定量评价方法奠定基础。结果表明，心材色泽参数L*和b*与提取物总黄酮含量呈显著正相关(相关系数分别为-0.93和-0.86)。在此基础上，采用超高效液-质联用技术对其提取物中的50种黄酮类成分进行了鉴定，并建立了16种主要成分的含量测定方法。在主要成分中，甘草素、达伯金、钙胶原、大豆苷元和非瑟素与L*或b*均呈显著负相关。本研究为建立香黄檀心材质量评价方法提供了依据。
The objective of this study was to identify the flavonoid chemical compositions of Dalbergia odorifera heartwood extracts, to investigate their correlation with heartwood color, for establishing an evaluation method for quantifying the quality of the heartwood. The results showed that the heartwood color parameters, L* and b*, were significantly correlated with the total flavonoid contents of the extracts (correlation coefficients of-0.93 and-0.86, respectively). Furthermore, 50 flavonoid components in the extracts were identified by ultra-high -performance liquid chromatography-mass spectrometry (UHPLC-MS), and a method for determining the con-tents of 16 major components was established. Among the major components, liquiritigenin, dalbergin, caly-cosin, daidzein and fisetin had significant negative correlations with both L* or b*. This study provides a basis for the establishment of evaluation methods to determine the quality of Dalbergia odorifera heartwood.
