[Studies on chemical constituents from moss Rhodobryum roseum II].
OBJECTIVE
To study the chemical constituents from Rhodobryum roseum.


METHODS
The compounds were isolated and purified by recrystallization and chromatography with silica gel and sephadex LH-20 column. Their structures were identified by physicochemical properties and spectral analysis.


RESULTS
Eight compounds were isolated and identified as apigenin (1), quercetin (2), oleanolic acid (3), 2alpha-hydroxyoleanolic acid (4), 2alpha-hydroxyursolic acid (5), protocatechuic acid (6), p-hydroxybenzoic acid (7), p-hydroxycinnamic acid (8).


CONCLUSIONS
Compounds 1-8 were isolated from R. roseum for the first time.
