[Study on flavonoiels and phenolic acids from the herb of Lygodium japonicum].
OBJECTIVE
To study the chemical constituents of the herb of Lygodium japonicum.


METHODS
The constituents isolated by column chromatography and their structrues were elucidated through spectroscopic analysis.


RESULTS
The compounds were identified as 3,4-dihydroxyl benzoic acid 4-O-beta-D-(4'-O-methyl) glucopyranoside (I), protocatechuic acid (II), acacetin 7-O-(6'-O-a-L-rhamnopyranosyl)-beta-sophoroside (III), 6,8-di-glucosylapigenin (vinenin) (IV), tricin-7-O-beta-D-glucopyranoside (V), 2-anilino-1,4-naphthoquinone (VI).


CONCLUSIONS
All these compounds are obtained from Lygodiaeae for the first time.
