| titleOfInvention | A method of extracting flavones from Leaves of Dendrocalamus Latiflorus |
| abstract | The present invention relates to the Extracting Technique of Flavonoids fields from Leaves of Dendrocalamus Latiflorus, especially a kind of method that flavones is extracted from Leaves of Dendrocalamus Latiflorus, it is handled by the way that Leaves of Dendrocalamus Latiflorus is protected from light preservation under rear low temperature environment, it is pulverized and sieved again, avoid the loss of flavones, also reduce the difficulty of extraction, after being extracted again using ethanol water, filtering, Bi-aqueous extraction, high speed centrifugation processing, ultrafiltration, macroporous resin adsorption, it is washed using Diluted Alcohol aqueous solution, it is parsed again using high concentration ethanol aqueous solution, it avoids and uses chloroform, the organic solvents such as ethyl acetate carry out the step of back extraction purification, and rear spray drying treatment is concentrated under vacuum in the eluent containing flavones, avoid the residual of ethanol water, reduce production cost, improve the quality of flavones, so that the flavones product purity prepared is 70% or more (in terms of rutin), it does not examine Heavy metal ion is measured, there is preferably quality. |
