Abstract: Supercritical carbon dioxide extraction had been used in the extraction conditions for carotenoids from the marigold flower (Tagetes erecta L.). Five significant factors (particle size, temperature, pressure, time and co-solvent addition) on total carotenoid yield were obtained using one-at-a-time design (p≤0.05). The optimal extraction conditions were 55 oC, 50 MPa and 180 min. Under these conditions, the yield of carotenoids was 6.872mg/g.
