Abstract: In order to extracting and analyzing red radish pigments, the thin-layer chromatography and column were usedto study the optimum factors such as the quantity of pigment, developing agent, developing time etc. That would affect the pigmentsextraction. The experiment showed that both the silica gel G used as the fixed phase and the mixture solution ratio of anhydrousalcohol and water at (5:1, V/V) were the optimum conditions.

Key words: red radish, thin-layer chromatography, column chromatography, extraction
