摘要：

【Objective】The chemical compositions of extracts, anatomical characteristics and plant morphology were compared between Dalbergia odorifera and D. tonkinensis, and the distinguishability of them was explored to provide a basis to determine whether they were the same species. 【Method】Observation method was used to observe the tree morphological characteristics of D. odorifera and D. tonkinensis. Wood anatomical method was used to observe the three dimensional sections of wood, wood tissue structure of D. odorifera and D. tonkinensis were observed by means of macroscopic and microscopic perspectives. The chemical compositions of extracts of D. odorifera and D. tonkinensis were checked by GC/MS and UPLC-ESI-MS/MS method and a comparative analysis was made. 【Result】The flowers, fruits, and leaves of D. odorifera were similar to those of D. tonkinensis. Compared with D. tonkinensis, the grain of D. odorifera was slightly rich. The pore type belonged to the semi-ring porous wood and the heartwood had slightly less heterogeneous-III ray tissue, but these differences were difficult to quantify. Thus, it was difficult to distinguish between the two species and other structural features were not distinguishable. The wood from the same latitude was clustered into one group by cluster analysis and the chemical compositions of the extracts from them had no relation with species. Similarly, the PCA analysis showed no distinguishability because of obvious intersection between the two groups. 【Conclusion】There are no significant differences in the morphological characteristics of flowers, fruits and leaves, the anatomical structure of wood and the chemical compositions of extracts from D. odorifera and D. tonkinensis. Therefore, there was no distinguishability between the two species. © 2021, Editorial Department of Scientia Silvae Sinicae. All right reserved.
