Rapid determination of chlorogenic acid and related compounds in sunflowerseeds by highperformance liquid chromatography/atmospheric pressure chemical ionization mass spectrometry
Ma. Aramendia et al., Rapid determination of chlorogenic acid and related compounds in sunflowerseeds by highperformance liquid chromatography/atmospheric pressure chemical ionization mass spectrometry, RAP C MASS, 14(12), 2000, pp. 1019-1022
High-performance liquid chromatography (HPLC) in combination with atmospher
ic pressure chemical ionization mass spectrometry (APcI-MS) was applied to
the determination of the phenolic fraction found in methanolic extracts of
sunflower seeds (mainly chlorogenic acid and derived compounds). These extr
acts were directly separated by HPLC and detected by both negative and posi
tive APcI-MS. Abundant structural information about these compounds can be
obtained even at low extraction cone voltages. This method has been shown t
o be a rapid and effective method for the analysis of crude extracts from s
unflower seeds. Copyright (C) 2000 John Wiley & Sons, Ltd.
