Abstract:
A process for obtaining a liquid extract of cartilage having a substantial portion of the biologically active components present in intact cartilage, which comprises the following steps:a) homogenizing the cartilage in an aqueous solution in conditions which are non-denaturing towards biologically active components, until the cartilage is reduced to solid particles whose size is lower than or equal to about 500 .mu.m;b) extracting said biologically active component into said aqueous solution which results in a mixture of solid particles and of a crude liquid extract having said biologically active components;c) separating said crude liquid extract from said solid particles; andd) further separating the crude liquid extract so as to obtain a final liquid extract containing cartilage molecules having a molecular weight lower than about 500 Kilodaltons (Kda);with the proviso that the cartilage is not shark cartilage.
