[Resources and secondary metabolites from Eleutherococcus plants: a review].

The genus Eleutherococcus includes multiple medicinal plants that hold significant value in the fields of medicine, health, economy, and food. The resources of this genus are widely distributed and rich in secondary metabolites. The secondary metabolites reported in Eleutherococcus plants include various types, such as terpenoids, phenolic acids, flavonoids, and lignans, which exhibit pharmacological activities such as anti-inflammatory, anti-tumor, antioxidant, and neuroprotective effects. Among these, the triterpenoid components in Eleutherococcus plants have garnered significant attention. This review summarized the research progress on the resource distribution, species classification, secondary metabolites, and pharmacological activities of Eleutherococcus plants and discussed their ecological significance, pharmacological development, and future research directions, with the aim of providing references for species conservation, drug development, and disease treatment involving Eleutherococcus plants.
