Abstract
[Objective] To investigate the optimum extraction technology of total flavonoids from celery leaves by using Soxhlet extraction method, so as to provide a theoretical basis for the development and utilization of celery leaves. [ Method] With the ethanol as the solvent,Soxhlet method was adopted to extract total flavonoids from celery leaves. Effects of ethanol concentration,extraction time,extraction temperature and solid-liquid ratio on the yield of total flavonoids were res|)ectively investigated through the single-factor test. [Result] Factors that affected the yield of total flavonoids were in the order of ethanol concentration > solid-liquid ratio > extraction temperature > extraction time. The optimum technology conditions of total flavonoids from celery leaves by using Soxhlet extraction method were us follows:ethanol concentration of 60% ,extraction time of 1 h .extraction temperature of 70 ℃ and solid-liquid ratio of 1: 60. Under the optimum condition, the yield of total flavonoids was 47.85 mg/g. [Conclusion] The Soxhlet extraction method was available for extracting total flavonoids from celery leaves.关键词
