Study On Extraction And Properties Of Flavonoids In Nicandraphysaloides

In this study, study on the extracting Flavonoids from Nicandra physaloides usedethanol-water solution as extracting solvent and use the macroreticular resins toseparation and purification Flavonoids. Study on the extracting Flavonoids fromNicandra physaloides used ethylene glycol. At the same time, study on purificationantioxidation and identification of Flavonoids Typeby Electrospray ionizationmulti-stage tandem mass spectrometer Flavonoids, Purification antioxidation ofFlavonoids,use HPLC-MS determine configuration of Flavonoids. Paper are as follows:1. First of all, Study on the process of extracting Flavonoids from Nicandraphysaloides, confirm the extact technics of Flavonoids.2. Secondly, Macroreticular resins are studied to separate and purify Flavonoids,determine the DA-201macroreticular resin is the best.3. Study on the Purification antioxidation of Flavonoids, confirm the extacttechnics of Dihydroquercetin. Compare the four synergistic agent of Vc、BHT、EDTA、Citric acid are synergized action.4. Identification of Flavonoids Typeby Electrospray ionization multi-stage tandemmass spectrometer.
