Résumé
Objective To compare the toxicity and anti-inflammatory effect of total saponins from Panax japonicus by different extraction technology. Methods The total saponins of sample 1, sample 2, sample 3, sample 4, sample 5 and sample 6 was prepared respectively by different process, and RAW264.7 cells were treated with the samples of different concentration. Then cells morphology was observed under microscope, thiazolyl blue (MTT) method was used to detect cell activity, the nitric oxide (NO) release of RAW264.7 cells was detected with NO kit. Results The cell toxicity of different samples from low to high was as follows:sample 4sample 5>sample 2>sample 6>sample 1>sample 3. Conclusion Among these six different kinds of extraction process of total saponins from Panax japonicus, the total saponins extract by foam fractionation has not only the minimal toxicity, but also the best primary anti-inflammatory effect.
