Isolation of Total Saponins from Sapindus mukorossi Gaerth


The study has been carried out to investigate the effects of single factors such as solvents extraction temperature, times, solid-liquid ration, and the time of extractions on the yields of saponins present in the pulp of Sapindus mukorossi Gaerth. On this basis, an L9 orthogonal design of experiment was adopted to determine the optimal conditions for the extraction of saponins. The factors that influence the extraction of saponins are put in the order of extraction times, extraction time, solid-liquid ration, and the best combination is that the powder of the pulp is extracted with EtOH (solid-to-solvent ratio = 1:8, w/v) for three times at 60°C for 3 hours. Under these conditions, about 1.63 g saponins will be extracted from 10 g raw material. The stability test showed that the Sapindus mukuross saponins can maintain surface activity at water temperature (25°C - 40°C), pH (6.3 - 7.7) and water hardness (50 - 250 mg.L-1). It is proved that Sapindus mukuross saponins are quality non-ionic active agent.
