The results showed that the ultrasonic extraction is a rather ideal method of extracting red P. tha fortuneana pigment. Cyanidin3glucoside can be hydrolysised to aglycon cyanidin under the conditions of 90℃, 9％HCl and 11min.Silica gel thinlayer chromatography with developping agent benzene∶ethyl acetate∶formic acid = 2∶2∶1 is better to separate cyanidin. Cyanidin is stable to heat and light, unstable to Zn2+ and Fe3+ and Cu2+, insensitive to Co2+ and Bi3+, befitting to acidic condition.
