摘要

Classification of Ephedra has long been a matter of debate, as Ephedra plants have few morphological characteristics to aid classification. In particular, the distinction between E. equisetina and E. major subsp. procera is uncertain. Thus, in this study, an attempt was made to clarify their relationship by molecular analysis and content of ephedrine alkaloids. Molecular analysis revealed that E. equisetina and E. major subsp. procera have a close relationship with differing matrilineage, and chemical analysis showed that they have the same characteristic of varied alkaloid composition ratio by collection site. We suggest that on the basis of molecular phylogeny that E. major subsp. procera should be treated as a synonym or subspecies of E. equisetina instead of a subspecies of E. major.
