The invention discloses an on-line control method for a preparation process of fructus gardenia. In order to solve the technical problem of lack of objectivity caused by taking the personal experience in observation of color as a sole control method in the preparation process of the traditional Chinese medicine fructus gardenia in the prior art, the invention introduces a technique capable of accurately quantifying traditional Chinese medicine appearance and color and a method for directly measuring color of fruit peels and seed kernels of various fructus gardenia decoction pieces. The method is characterized by quantifying the color data, carrying out statistical calculation, determining a mathematic discrimination function of the fructus gardenia and applying the function to the on-line control of the preparation process of the fructus gardenia decoction pieces. When the method is applied to the on-line production of the fructus gardenia, the stability of the quality of the ructus gardenia decoction pieces can be ensured; the method has the advantages of objectivity, rapidity and reliability; the technical problem of lack of objectivity caused by artificial judgment in the prior art can be solved.
