Examples of plants in this family include the buckthorns (Rhamnus), coffee trees (Coffea), and the familiar invasive species, Japanese knotweed (Fallopia japonica).

'Ziziphus' är ett släkte inom familjen Rhamnaceae, och innehåller cirka 40 arter av buskar och träd som förekommer naturligt i varma och tempererade områden över hela världen. Ett vanligt känt exemplar är jujubeträdet (*Ziziphus zizyphus*), vars frukter, även kallade jujuberor, har använts i traditionell medicin för att lindra symptom på bland annat sömnsjuka, hosta och diarré.
