| targeting high-performance liquid chromatography-high-resolution mass spectrometry-solid-phase extraction-nuclear magnetic resonance analysis with high-resolution radical scavenging profiles-bioactive secondary metabolites from the endophytic fungus penicillium namyslowskii. | the high-resolution radical scavenging profile of an extract of the endophytic fungus penicillium namyslowskii was used to target analysis by high-performance liquid chromatography-high-resolution mass spectrometry-solid-phase extraction-nuclear magnetic resonance spectroscopy, i.e., hplc-hrms-spe-nmr, for identification of anti-oxidative secondary metabolites. this revealed the two chromatographic peaks with the highest relative response in the radical scavenging profile to be griseophenone c a ... | 2013 | 23827469 |
