Keywords:
Taxus, Character identification, Microscopic identification, UPLC-Q-TOF-MS/MS, TaxolAbstract
Objective: To study the seeds and arils of Taxus wallichiana var. chinensis and other Taxus plants at different levels, to provide a scientific basis for expanding the medicinal resources of Taxus wallichiana var. chinensis. Methods: The five species of Taxus seeds were compared by the traditional methods of character identification and microscopic identification. The main chemical components were detected by UPLC-Q-TOF-MS/MS method, and compared with the reference and known components. Results: The five species of Taxus seeds had high similarity in appearance and microscopic characteristics of the seed coat. There were only a few differences, such as seed surface color, seed umbilical shape and microscopic morphology of seed epidermis. After detection and comparison, five samples contained taxane compounds, and there were eleven common components. Conclusion: There are few differences in seed morphological characteristics of the five species of Taxus seeds, and they all contain eleven taxanes. The results have guiding significance for the subsequent development and utilization of Taxus medicinal resources.
