Abstract:

There are about 700 species of Rubus widely spreading in the world, about 194 species in our country11. Their traditional use is for bums. There will be no scar on the skin after recovery. Our research indicated the predominant constituents were triterpenoids and tannins. The primary activity assay revealed that the EtOAc extracts had anti-bacteria and anti-fungi activity. We now report the triterpenoids from these three plants.
