Abstract: The technologies of extracting and refining total flavones from the marc of Sea buckthorn were studied in this article.The optimum technological conditions were obtained by orthogonal experiment as follows: degreasing with benzinum, extractedwith 65% ethanol, extraction temperature 80℃, extracting 3 times (1h for each time) and the ratio of material to solvent 1:8 (W/V).Macroreticular adsorptive resins were used to refining total flavones. The results showed that X-5 resin was a perfect adsorbentto refine total flavones of Sea buckthorn.

Key words: marc of Sea buckthorn, total flavones, extract, refine
