Putranjiva is a plant genus of the family Putranjivaceae, first described as a genus in 1826. It is native to Southeast Asia, the Indian Subcontinent, Japan, southern China, and New Guinea. Along with Drypetes (of the same family), it contains mustard oils as a chemical defense against herbivores. The ability to produce glucosinolates is believed to have evolved only twice, in the Putranjivaceae and the Brassicales.
