Abstract
Abstract Polyprenyl derivatives having the formula ##STR1## in which R 1 and R 2 may be the same or different and each represents hydrogen atom, hydroxyl group, an alkoxy group having 1-8 carbon atoms, an aliphatic acyloxy group having 2-18 carbon atoms, an aromatic acyloxy group or an araliphatic acyloxy group having 2-3 carbon atoms in the aliphatic acyl moiety, R 3 represents hydrogen atom, an alkyl group having 1-8 carbon atoms, an aliphatic acyl group having 2-18 carbon atoms, an aromatic acyl group or an araliphatic acyl group having 2-3 carbon atoms in the aliphatic acyl moiety, n is an integer of 1-4 and, when n is an integer of 2-4, R 2 's may be the same or different; provided that, when n is 1 or 2, at least one of R 1 and R 2 's is hydroxyl group, an alkoxy group, an aliphatic acyloxy group, an aromatic acyloxy group or an araliphatic acyloxy group. These derivatives are useful as medicines for treating peptic ulcer.
