Abstract

Crude extracts of Cystoseira balearica were submitted to pharmacological investigations. The chloroform-methanol residue caused relaxation of the rat aortic musculature and an inhibitory action on the guinea pig atria. The fractionation of this crude extract gave two active diterpenoids, eleganolone (1) and elegandiol (2), the latter has not previously been isolated from this alga. These pure components, never before tested, showed a higher activity when compared with the crude residue.
