Alpinumisoflavone is a pyranoisoflavone, a type of isoflavone. It can be found in the bark of Rinorea welwitschii.^[1] It can also be found in the molluscicide plant Millettia thonningii and is thought to be an antischistosomal agent^[2] since it has been shown to kill the snails which transmit the schistosomiasis and also the larvae of the parasite itself.^[3]
