摘要: Abstract Two new meroterpenes have been isolated from the brown seaweed Cystoseira usneoides usneoidone E and Z. Their structures were established mainly by means of 2D NMR experiments: 1 H/ H (COSY) 13 C one bond long range (HCCORR) correlations. Both compounds exhibit antitumoural antiviral activities.
