STUDIES ON CHEMICAL CONSTITUENTS OF PHELLODENDRON CHINENSE SCHNEID BARK

QIN Min-jian, WANG Heng-qi(Department of Resources Science of Chinese Medicinal Materials,China PharmaceuticalUniversity,Nanjing 210038,China)  
Chemical constituents of bark of Phellodendron chinense Schneid(Chuan Huang Bo),used as one kind of traditional Chinese medicine,were studied.Two point five kg powder of the barks of P.chinense were extracted with water(8 times of the materials) for 3 times,and each time for 2 h.Then,add ethanol to extracts until the ethanol concentration about 80%,filt in vacuum,concentrate the filtrate and remove ethanol completely.The residue were extracted successively with ether,ethyl acetate and n-BuOH,and the solutions were recovered.Column chromatography was used for separation and purification.The structure of compounds were elucidated by spectral analysis.Six compounds were isolated and identified as obacunone(I),obaculactone(II),berberine(III),palmatine(IV),daucosterol(V) and (+)-ethyl-5-O-feruloyquinate(VI).Compound VI is a novel compound and compound I was first obtained from this plant.
