[Material basis of stench of animal medicine: a review].

Despite the distinctive characteristics and remarkable efficacy, animal medicine is stenchy, which decreases the comp-liance of patients. At the moment, the research on the method for deodorizing animal medicines lags behind. To be specific, the components related to the odor and the basic properties transformation of the components are unclear and there is a lack of specific deodorizing method. This study aims to clarify the main components related to the stench of animal medicine, such as aldehydes, amines, trimethylamines and sulfur compounds, and their basic properties, and to explore their metabolism and transformation in vivo and in vitro, which is expected to serve as a reference for the research on deodorization of animal medicine and development of new techniques.
