应用
- Micellar electrokinetic chromatography for separation of a mixture of coptis alkaloids, scute flavonoids, and rhubarb anthraquinones and bianthrones.: This study by Chang and Sun investigates the use of micellar electrokinetic chromatography (MEKC) to separate complex mixtures of bioactive compounds. The research highlights the effectiveness of di-Sodium tetraborate in optimizing the separation process, showcasing its utility in analytical chemistry for the precise analysis of natural products (Chang et al., 2006).
