Etymology: Strophanthins are a family of cardiac glycosides, and their name is built from the plant genus that produces them, "Strophanthus," a group of African and Asian climbing shrubs and vines. The genus name itself is a compound from Greek: "strophos" meaning "twisted cord" or "twisted band," and "anthos" meaning "flower," a reference to the long, twisted, ribbon-like petals of the flowers. The chemical suffix "-in" is a conventional ending used for many substances isolated from plants, so the word reads as "the twisted-flower substance." Strophanthins are plural because the name covers several closely related compounds extracted from the plant's seeds, which are distinguished from one another by small structural differences. The singular "strophanthin" names one such compound or a mixture of them, and the plural form is used when discussing the group as a whole.
