The invention relates to a method for screening a
lipase inhibitor and particularly relates to a method for screening a
lipase inhibitor by using a thin-layer
chromatography bioautography. The method comprises the following steps of: dissolving a sample to be tested into water and / or an
organic solvent, dispensing liquid of the sample to be tested on a thin-layer plate, placing the plate in a developing agent for developing, taking out the plate, and airing the plate for later use; and dipping the obtained thin-layer plate into substrate liquid, dipping the thin-layer plate into
lipase liquid after completing
solvent evaporation, taking out the thin-layer plate and subjecting the thin-layer plate to an enzymatic reaction at the temperature of 20-40 DEG C, and dipping the thin-layer plate into developing agent liquid for
color reaction after completing the enzymatic reaction, thereby obtaining a white and / or brown-yellow spotted result diagram with a purple background. The method for screening the lipase inhibitor has the advantages that complicated instruments and devices are not required, the operation is simple, and the testing cost is low, so that the method is suitable for general laboratories; and the sensitivity and specificity are higher than those of conventional screening methods, and screened results are visual and easily recognized and remembered.
