Abstract: It studied the effection under different kinds of leaching medicament, leaching temperature, leaching time, leaching medicament pH and different rate of Prunus virginiana’s leaves and leaching medicament. The result shows that it can be extracted most well when pH 3, using distilled water as leaching medicament and extracting for 50 minutes at 60 ℃. Then we can use AB-8 colophony to adsorb and use 40% ethanol to elution to get purer pigment. The content of pigment extracted reaches 1.6%.

Key words: Prunus virginiana, pigment, extraction, determine
