| titleOfInvention | Hydrophobic deep eutectic solvent for removing ginkgolic acid in crude ginkgo leaf extract by liquid-liquid micro extraction, and preparation method and removal method thereof |
| abstract | The invention discloses a hydrophobic deep eutectic solvent for removing ginkgolic acid in a crude ginkgo leaf extract by liquid-liquid micro-extraction, and a preparation method and a removal method thereof, wherein the hydrophobic deep eutectic solvent is prepared from menthol, hexanol and lauric acid according to a molar ratio of 1:0.9: 0.1-1: 0.4: 0.6. The hydrophobic deep eutectic solvent is simple and quick to prepare; the hydrogen bond is stable, the fluidity is good, the solvent is green, and the characteristics of easy biodegradation, no environmental pollution, high biocompatibility and the like are achieved; the method for removing the ginkgolic acid in the crude ginkgo leaf extract by liquid-liquid micro-extraction of the hydrophobic deep eutectic solvent prepared by the invention can reduce the content of the ginkgolic acid in the crude ginkgo leaf extract to be below 5ppm, simultaneously reserves the content of functional components such as ginkgo flavonoids, terpene lactones and the like in the crude ginkgo leaf extract, and has the advantages of simple, convenient, fast and safe operation, high removal efficiency, low cost and no harm to the environment and human bodies. |
