Liquid chromatography–mass spectrometry analysis of propolis

Phytochemical Analysis, 2001
AbstractThe composition of propolis, a resinous hive product collected by honeybees from various plant sources, depends on various factors such as season and vegetation of the area. Based on standards (either isolated from Brazilian propolis or reported from propolis) including chromane, diterpenes and phenolic compounds, different Brazilian propolis ...

Characterization of powdered turmeric by liquid chromatography-mass spectrometry and gas chromatography-mass spectrometry

Journal of Chromatography A, 1996
Five commercial powdered turmeric samples were analyzed to identify major and minor components. The developed HPLC method allows the separation of curcumin, demethoxycurcumin and bisdemethoxycurcumin, as well as three other major components and numerous minor components.

Integrated gas chromatography-mass spectrometry

Quarterly Reviews of Biophysics, 1973
Mass spectrometric analysis of organic compounds was in the early 1950s done mostly for quantitative determination of petroleum products. The use of the mass spectrometer for qualitative analysis of solid organic material samples was shown by O'Neil & Wier (1951) and since then a continuous increase in mass spectrometric studies of different ...

Supercritical Fluid Chromatography/ Mass Spectrometry

1992
The field of supercritical fluid chromatography (SFC) has experienced a phenomenal growth during the decade of the 1980s, both in terms of publications and practitioners. A noteworthy observation is that the early publications in capillary SFC [1–3] were quickly followed by descriptions of capillary SFC/mass spectrometry (SFC/MS) [4, 5].
