[Study on chemical constituents of Cyclocarya paliurus].
Phytochemical investigation of chemical constituents of the CHCl3 fraction of 75% alcohol extract from the leaves of Cyclocarya paliurus has resulted in the isolation of five compounds, alpha-boswellic (I), beta-boswellic (II), Oleanolic acid (III), 4-hydroxyl-3-methoxyl-benzoic acid (IV) and 3,6,3',5'-tetramenthox-5,7,4'-trihydroxy-flavonol (V). Their structures were elucidated on the basis of spectroscopic analyses, especially NMR. Compunds I, II, IV and V were obtained from this plant for the first time.
