Abstract: In this study, one-factor-at-a-time and orthogonal array design methods were used to optimize the conditions for hot reflux extraction of total flavonoids from the shoot of Salicornia europaea L. The determination of total flavonoids was spectrometrically carried out using rutin as the reference standard. The optimal conditions for extracting total flavonoids from the shoot of Salicornia europaea L. were 80% ethanol as the extraction solvent, solid/liquid ratio 1:50, extraction temperature 70 ℃, and extraction time 4 h, resulting in a total flavonoid yield of 25.172 mg/g.

Key words: Salicornia europaea L., total flavonoids, hot reflux extraction, orthogonal test
