Novel compounds, 3,5-di-tert-butylstyrene derivatives and their salts, are disclosed, which derivatives are represented by the general formula: ##STR1## wherein R.sup.1 stands for an acyloxy group represented by R.sup.3 COO (R.sup.3 is a hydrogen atom or an alkyl group with C.sub.1 -C.sub.6), an alkoxyl group of R.sub.4 O (R.sup.4 is an alkyl group with C.sub.1 -C.sub.4), a hydroxyl group, or a hydrogen atom; R.sup.2 stands for ##STR2## (R.sup.5 is a hydrogen atom or an alkyl group with C.sub.1 -C.sub.3 and X.sup.1 is CH.sub.2 or an oxygen atom), ##STR3## (R.sup.5 and X.sup.1 are each the same as defined above), or ##STR4## (X.sup.2 is an oxygen or sulfur atom). There are also disclosed an anti-inflammatory, analgesic, and antipyretic pharmaceutical composition and an anti-platelet aggregation pharmaceutical composition, both pharmaceutical compositions comprising the foregoing 3,5-di-tert-butylstyrene derivative or its pharmaceutically acceptable salt as an active ingredient in association with pharmaceutical excipients.
