Study on extraction of total flavones from Epiphyllum Flos
摘要
Abstract
To study on the optimum extracting technology of total flavonoids of Epiphyllum Flos.The traditional hot reflux extraction was used.With ethanol as extraction solvent, the factors of the extraction conditions, such as the concentration of ethanol, extraction tempera-ture, the extraction time and the solid-liquid ratio were studied.On the basis of single fac-tor experiments, the optimum extraction process was determined by orthogonal test.The re-sults of the one-factor experiments showed that these factors all affected the content of total flavonoids of Epiphyllum Flos.When the concentration of ethanol was 80%, extraction tem-perature was 80 ℃, the extraction time was 4 h and the solid-liquid ratio was 1∶40 ( g/mL) , the content of total flavonoids was higher.The optimal preparation conditions by or-thogonal test were 80% ethanol, 90 ℃ and 4 h and the content of total flavonoids was 1. 18%.In conclusion, the optimized extraction process was simple and feasible.The study lays the foundation for further development and utilization of Epiphyllum Flos.关键词
