action | vitexin glucoside is a unique flavonoid component in hawthorn leaves. in vitro experiments show that it has significant antioxidant effect. As one of the main flavonoids in hawthorn leaves, through the analysis of hawthorn leaf extract total flavonoids in vitro and in vivo experimental results, it is preliminarily determined that vitexin glucoside plays a certain role in the treatment of hyperlipidemia, fatty liver and the protection of heart function. |
prepare | 60g crude extract of hawthorn leaves, add 500mL distilled water for ultrasonic dissolution, filter out insoluble matter, and flow through HPD-400 macroporous resin column at a flow rate of 3BV/h; After the adsorption is completed, the HPD-400 macroporous resin column is fully eluted with 5BV distilled water to collect the first stage eluent, after concentration and freeze-drying, 5.49g of chlorogenic acid compound with a purity of 70.3% was obtained. HPD -400 macroporous resin column was fully eluted with 5BV 50% ethanol aqueous solution, the second-stage eluent was collected, and 19.32g of hawthorn leaf total flavonoids with a purity of 59.7% were obtained after decompression distillation and recovery of solvent. The total flavonoids of hawthorn leaves are dissolved in 50mL methanol and refined by preparative chromatography {C18 column (50 '250mm,10 μm),35/65(V/V) 0.1% acetic acid aqueous solution/methanol}, the monomer eluent was collected respectively, and after distillation under reduced pressure, 0.29g of vitexin glucoside with purity of 96.2% and 1.29g of vitexin rhamnoside with purity of 96.3% were obtained. |
