Objective:
To study the chemical constituents of Geranium eristemon.
Method:
Chromatography and spectral analysis were used to isolate the constituents and elucidate their structures.
Result:
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.
Conclusion:
kaempferol-7-O-alpha-L-arabifuranoside and kaempferol-3-O-alpha-L-arabifuranoside were isolated from G. genus for the first time.
