High-performance liquid chromatography and LC-ESI-MS method for identification and quantification of two isomeric polyisoprenylated benzophenones isoxanthochymol and camboginol in different extracts of Garcinia species.

30 Jul 2009 A rapid, sensitive and simple reverse-phase high-performance liquid chromatography-electrospray ionization mass spectrometric method has been developed for the identification and quantification of two isomeric polyisoprenylated benzophenones, ... Read more...

Aromatic cyclic peroxides and related keto-compounds from the Plakortis sp. component of a sponge consortium.

30 Jul 2009 Six unreported aromatic compounds, 1-6, were isolated, along with the known compounds dehydrocurcuphenol and manoalide, from a sample of Plakortis sp., which was the main component of a Pacific sponge consortium. The new molecules were chemically ... Read more...

LC-MS and LC-PDA analysis of Hypericum empetrifolium and Hypericum sinaicum.

29 Jun 2009 Within the framework of our continuous efforts to explore Hypericum species from Jordan, we report the analysis of the major active metabolites, naphthodianthrones and phloroglucinols, in the methanolic extracts of two under-explored Hypericum ... Read more...
