A sustained relase aromatic composition comprises a clathrate compound composed of a perfume and a polyphenyl compound and gives out fragrance slowly but steadily over a long period of time. It is produced by a process comprising melting under heat a perfume which is a solid at room temperature, and adding a polyphenyl compound to the molten perfume. Alternatively, a perfume which is a liquid at room temperature is mixed with a polyphenyl compound so that they may react with each other, and a solid reaction product is separated from the resultant mixture.
