With leaves of Dimocarpus longan, Murraya jasminorage, Dracaena sanderiana as materials, different blanching liquid, blanching temperature, blanching time and soaking liquid on influencing green leaves specimen processing were studied. The results showed that using 20 g/L sodium thiosulfate and sodium carbonate ( w/w 5∶1) solution in 90～95℃ after 20～30 s, then immersed them to continue 30～40 minutes by using 50 g/L sodium thiosulfate, sodium benzoate and sodium carbonate ( w/w 3.5∶0.5∶1) solution, after drying and embedded with methyl methacrylate prepolymer, the leaf specimen that after hardening, in the outdoor environment for more than 6 months, green color could still remain close to the fresh green degree.
