[Chemical constituents of Geranium eristemon].
OBJECTIVE
To study the chemical constituents of Geranium eristemon.


METHODS
Chromatography and spectral analysis were used to isolate the constituents and elucidate their structures.


RESULTS
Five compounds were isolated from acetone extract of the whole grass of G. eristemon, and identified as beta-sitosterol, protocatechuic acid, myricetin, kaempferol-7-O-alpha-L-arabifuranoside and kaempferol-3-O-alpha-L-arabifuranoside.


CONCLUSIONS
kaempferol-7-O-alpha-L-arabifuranoside and kaempferol-3-O-alpha-L-arabifuranoside were isolated from G. genus for the first time.
