Abstract:
ObjectiveTo study the effects of 9 different drying methods on total saponin content and antioxidant capacity ofParis polyphylla var.yunnanensis.Methods UV-VIS spectrophotometry was used for measuring the total saponin content ofP. polyphylla var.yunnanensis, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzthiozoline-6)-sulphonic acid (ABTS+) radical scavenging methods were used for evaluating the antioxidant capacity ofP. polyphylla var. yunnanensisextracts.ResultsThe total saponin contents ofP. polyphylla var.yunnanensis dried by different methods existed significant difference. The sample dried at 35℃ showed highest total saponin content (17.557 mg/g). The sample dried in the shade naturally showed middle total saponin content (13.740 mg/g). Based on the results of antioxidant capacity detected by two methods, the samples ofP. polyphylla var. yunnanensis dried by 9 different methods all showed good antioxidant capacity and showed a certain concentration dependence.Conclusion The samples dried at 35℃ have the highest antioxidant capacity. Therefore, drying at 35℃ is a better drying method to obtain high quality and high activity ofP. polyphylla var.yunnanensis.
