| Abstract: | In the paper, Onhogonal Experiment bas been employed to optimize the extraction process of paeoniflorin from Radix Paeoniae Rubra by supercritical carbon dioxide extraction, and determine the content of paeoniflorin in the extract by HPLC method. The extraction temperature, time and the extraction pressure were selected as the investigated factors. Three-factor-three-level Orthogonal Experiments were performed for study the effect of the investigated factors on the content of paeoniflorin in the extract. The results shown that the optimum extraction process of paeoniflorin from Radix Paeoniae Rubra by supercritical carbon dioxide extraction were as follow： the extraction pressure was 18 MPa, temperature at 25 ℃, and the extraction time was 1.5 h. |
