tilianin and kaempferol

To study the chemical constituents of Lygodium japonicum.. Column chromatographic techniques were used for isolation and purification of chemical constituents of this plant and their structures were identified by spectroscopic analysis.. Eight compounds were isolated and identified as tilianin (I), kaempferol-7-O-alpha-L-rhamnopyranoside (II), kaempferol (III), p-coumaric acid (IV), hexadecanoic acid 2, 3-dihydroxy-propyl ester (V), daucosterol (VI), beta-sitosterol (VII, and 1-hentriacontanol (VIII) respectively.. Compounds I, II, V, VI, VII, VIII were isolated from L. japonicum for the first time, compounds I, II, V were isolated from genus Lygodium for the first time.
