Abstract:
OBJECTIVETo study the chemical constituents of the whote plant Biebersteinia heterostemon (Geraniaceae).
METHODThe ethanol extract of the whole plants was separated by various chromatographic methods and the compounds from the extract were identified by spectroscopic evidence including MS, IR, NMR and X-ray crystallographic analysis.
RESULTThree isoprenyl guanidine derivatives were isolated from the whole plant of Biebersteinia heterostemon and identified as galegine (1) , cis-4-hydroxygalegine (2) and trans-4-hydroxygalegine (3).
CONCLUSIONThe three compounds were isolated from this plant for the first time.
