Bryoamaride is a chemical compound isolated from certain plants, notably Bryonia dioica.  It can be seen as a derivative of the triterpene hydrocarbon cucurbitane (), more specifically from cucurbitacin L or 23,24-dihydrocucurbitacin I.
The derivative 25-O-acetylbryoamaride is found in Trichosanthes tricuspidata.
