Used in traditional medicine in tropical countries to fight inflammation. The extract obtained from the steam distillation of the plant leaves, which was extracted with petroleum ether, is clinically used to treat skin diseases caused by sea-buckthorn injuries. Animal experiments have shown that the topical use of the extract has a significant anti-inflammatory effect, and in vitro tests have shown that it can inhibit the formation of prostaglandins. This paper reports the isolation of four active ingredients in extracts of two-leaved sweet potato and their inhibitory effect on prostaglandin synthesis.
