[Isolation and structure identification of chemical constituents from Viscum liquidambaricolum].
OBJECTIVE
To study the chemical constituents of Viscum liquidambaricolum Hayata.


METHODS
Various chromatographic techniques were used to separate and purify the compounds. Their spectral data (MS,IR,NMR) were measured for structure identification.


RESULTS
Five compounds were isolated from Viscum liquidambaricolum and their structures were identified as trans-cinnamic acid (I), oleanolic acid (II), chrysin (III), eriodictyol (IV) and liquidamboside (V).


CONCLUSIONS
Liquidamboside (V) is a new compound, the known compounds I - IV were isolated from this plant for the first time, I, III, IV were isolated from Loranthaceae for the first time.
