Abstract
There is provided a new ester of prostaglandin of the formula ##STR1## wherein R.sub.1 denotes an alkyl group having 1 to 20 carbon atoms; R.sub.2 denotes a hydrogen atom or a lower alkyl group having 1 to 4 carbon atoms; and X denotes a group represented by the formula ##STR2## The new ester dissolves in oil easier than prostaglandin I.sub.2 itself and can easily be emulsified in the form of particles of solution in a vegetable oil. The ester in the fat emulsion is more stable than prostaglandin I.sub.2 and its physiological acts which are the same as prostaglandin I.sub.2 are prolonged.
