Geum aleppicum Jacq., a kind of perennial herbaceous plant ,which is widely distributed in the Northeast China and the Far East,especially abundant in the Changbaishan area,has been used in traditional Chinese medicine for many years. Its whole plant or root can be used as herbal medicine and have the activitives of clearing heat and expelling miasma, exceeding discharge of urine, relieving swelling and causing analgesia.However, studies on chemical constituents of Geum aleppicum Jacq. Have not been reported domestically and abroad. Jiang yuan ping etal. only studied on the in vitro antimicrobial activity of the decoction, the water-soluble ingredients and the liposoluble ingredients.Therefore, we carried out some research on the chemical constituents of Geum aleppicum Jacq. in this paper.we focused on Flavones in Geum aleppicum Jacq..Eight compounds were isolated by organic extraction and chromatography. The structures of compounds isolated from Geum aleppicum Jacq. were identified through physical and chemical constants and spectroscopy.They were Kaempferol-3-O-(6''-O-E-p-coumaroyl)β-D-glucopyranoside Benzoic acid,Gallate acid,Salicylic acid,Vanillin,3,4,5-trihydox-ybenzoic dehyde,3,4,5-trihydoxybenzoic acid,ethyl ester and daucosterol.
