Abstract Four minor C 29 -steroids, poriferast-5-en-3β-ol (clionasterol), 3β-hydroxyporiferast-5-en-7-one, poriferast-5-en-3β,7α-diol and poriferasta-3,5-diene-7-one were isolated from the marineredalga, Gracilariaedulis . This is the first report of the characterization of the last three compounds from a natural source and of the first compound from a species of Gracilaria .
