Abstract
Extraction technology by ultrasonic is used to optimize the extraction condition of flavonoids,and stability of the total flavonoids in celery is studied.Extract factors include: solid-liquid ratio,solvent concentration,extraction time and so on,and their influence on the content of the total flavonoids in celery is discussed.Orthogonal test result shows: The optimal processing conditions are that the solid-liquid ratio is 1∶ 40,ethanol concentration is 80% and extract for 30 minutes.The content of celery total flavonoids is 9.0154mg / g in this condition.The stability of celery total flavones is better in the conditions of that pH is 4-6,temperature belows 50 ℃,and the low concentration glucose solution(≤ 1%),sodium chloride solution(≤ 0.5%) and citric acid solution(≤ 1.5%).
