Abstract:

The objective of this study was to optimize extraction technology of total flavonoids with ethanol by heat reflux extraction method. Based on single-factor test, the optimal extraction conditions of total flavonoids were determined by orthogonal test as follows: ethanol concentration 95%, extraction temperature 65 ℃, solid to liquid ratio 1:25, and extraction time 2 h. Under these conditions, the extraction yield of total flavonoids was 10.60%.

Key words: Longwangmao sugary almond, total flavonoids, extraction technology
