OBJECTIVE To study the preparation technique of microcapsules of U. fissa Pritz extract. METHODS The method of orthogonal design was used to study the preparation technique of microcapsules of U. fissa Pritz extract. RESULTS When the ratio of coating material to U. fissa Pritz was 0. 5：1.25, temperature of capsulation was 70 ℃,and a rate was 800 r. min^-1, the highest rate of production could be obtained. CONCLUSION The technique is simple and reliable.
