  • Two new lignans, designated spicatolignan A (1) and spicatolignan B (2), were successfully isolated.
  • The chemical structures of these novel lignans were determined.

Conclusions:

  • The discovery of spicatolignan A and B adds to the known phytochemical profile of Mentha spicata L.
  • These findings contribute to the understanding of lignan diversity in the Lamiaceae family.
