Recovery of Anthocyanins from Hibiscus sabdariffa L. Using a Combination of Supercritical Carbon Dioxide Extraction and Subcritical Water Extraction
نویسندگان
چکیده
Anthocyanins are one of the bioactive compounds in roselle that has many medicinal proposes. placed inner part roselle; therefore, combinations two methods were applied to extract anthocyanins. The first stage is employing supercritical carbon dioxide (ScCO2) break particle surface or outer layer based on total phenolic (TPC) recovery, and second step was apply subcritical water extraction (SWE) for objective determine best conditions obtain high yields anthocyanins (TAC) from (Hibiscus sabdariffa) by a combination ScCO2 SWE. optimal (first stage) 19.13 MPa, 60 °C, 4.31 mL/min, yielding 18.20%, 80.34 mg/100 g TPC, respectively. optimum SWE (second 9.48 137 6.14 86.11% 1224.61 TAC, application integrated proved successful achieving production yield as compared previous methods. This approach may be used with greater anthocyanin’s concentration than prior method.

Subcritical water extraction (SWE) of essential oil from Matricaria Chamomilla L. (M. Chamomilla L.) was performed and compared with conventional method including hydro distillation. The percentage of main extracted components of different temperatures (100, 125, 150 and 175 oc) and water flow rates (1, 2 and 4 ml/min) were investigated at 20 bar pressure and 0.50 mm mean particle size in SWE....
