文档介绍:for this kind of medicine for invigorating the circulation lf blood and dissolving blood lumps. Now it is reported that only two triter- penoids were isolated from this plants. Modern medical experiments show that they exhibit in vitro antitumor activities of pencyclic triterpenoid from Rubus better exploit and make good use of this plant we have made studies of the constituents of the roots of Rubus Parvifolius. From the roots of this plant pounds were isolated through solvent extract and chromalography. The structure of pounds were identified by means of chemical and
spectroscopic analysis as -sitosterol ( ) euscaphic

compounds are triterpenoids .pounds , , , , and

We also used GC Ms to analyze the constituents of the essential oil from the roots and the leaves of Rubus Parvifolius finding out pounds.
Also, the study on the bacteriostatic ability of the essential oil from the roots and the leaves of Rubus Parvifolius had been carried out .the results show that the latter has bacteriostatic ability and the former hasn’ t.
