| titleOfInvention | Ultrasonic method extracts tea polyphenols |
| abstract | A kind of new process of tea polyphenol extract, belongs to natural product extraction preparation technical field, is related to the extraction of tea polyphenols.It is characterized in that using ultrasonic destruction cell in conjunction with tea polyphenols, the method for dissolving out tea polyphenols intracellular, it comprises the concrete steps that and tealeaves is placed in aqueous solution, solid-liquid ratio 1g:30mL-1g:50mL, control temperature is at 70 DEG C -80 DEG C under ultrasonic wave effect, time is 20min-40min, it takes supernatant 1mL in 25mL volumetric flask, the ferrous tartrate solution 5mL of 1mg/mL is added, with the phosphate buffer constant volume of pH7.0, its light absorption value is measured at 540nm, and tea polyphenols concentration is indicated with light absorption value.Carry out the recovery rate that analysis detection calculates tea polyphenols.The present invention solves the problems, such as that tea polyphenols dissolution is incomplete, improves the recovery rate of tea polyphenols. |
