HPLC Analysis of Flavonoids in Ginkgo Biloba
Reseachers from China Pharmaceutical University (Nanjing, China) used high performance liquid chromatography (HPLC) with photodiode-array detection and electrospray ionization mass spectrometry to analyze 12 flavonoids in Ginkgo biloba leaves.
Reseachers from China Pharmaceutical University (Nanjing, China) used high performance liquid chromatography (HPLC) with photodiode-array detection and electrospray ionization mass spectrometry to analyze 12 flavonoids in Ginkgo biloba leaves. They also used chemiluminescence detection to determine the free radical scavenging activity of the flavonoids. They found that the luminescent signal could be inhibited by flavonol glycosides, which means that they are responsible for the leaves’ antioxidant activity. Flavonoids in plants have been reported to have protective effects against oxidative injury.
LCGC’s Year in Review: Highlights in Liquid Chromatography
December 20th 2024This collection of technical articles, interviews, and news pieces delves into the latest innovations in LC methods, including advance in high performance liquid chromatography (HPLC), ultrahigh-pressure liquid chromatography (UHPLC), liquid chromatography–mass spectrometry (LC–MS), and multidimensional LC.
Next Generation Peak Fitting for Separations
December 11th 2024Separation scientists frequently encounter critical pairs that are difficult to separate in a complex mixture. To save time and expensive solvents, an effective alternative to conventional screening protocols or mathematical peak width reduction is called iterative curve fitting.
Mobile Phase Buffers in Liquid Chromatography: A Review of Essential Ideas
December 11th 2024In this installment of "LC Troubleshooting," Dwight Stoll discusses several essential principles related to when and why buffers are important, as well as practical factors, such as commonly used buffering agents, that are recommended for use with different types of detectors.
