The Japanese Pharmacopoeia Seventeenth Edition defines Oriental Bezoar as a stone formed in the gall sac of Bos taurus Linne var. domesticus Gmelin. It is used for the purpose of alleviation of fever, antispasmodic and cardiotonic effect.
It is a very expensive crude drug. Prices vary considerably depending on production areas and grades, and quality evaluation by origins, grades, color, odor, forms, and weight mainly using the five senses is not easy. It requires technical knowledge and experience; evaluators need long-term training, which causes a lack of skilled sensory evaluators.
It is effective to predict sensory evaluation by fingerprints identified by instrumental analysis to solve this problem. Therefore, we developed a prediction model of sensory evaluation by simpler operations with wildly-used HPLC. We confirmed that this model can assess the quality of Oriental Bezoar like the skilled evaluators.
