[Studies on the chemical constituents in herb of Lygodium japonicum].
OBJECTIVE
To study the chemical constituents of Lygodium japonicum.


METHODS
Column chromatographic techniques were used for isolation and purification of chemical constituents of this plant and their structures were identified by spectroscopic analysis.


RESULTS
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.


CONCLUSIONS
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.
