摘要:

本研究旨在提高云南兔耳草中总环烯醚萜苷的提取率,并评估其在体外抗氧化和抗炎活性方面的表现。采用闪式提取法在单因素实验结果的基础上,进行Box-Behnken响应面分析,优化后云南兔耳草中总环烯醚萜苷的平均提取率为10.56%,总环烯醚萜苷能够较好的清除DPPH、ABTS自由基并且对脂多糖诱导的RAW 267.4细胞炎症模型表现出抗炎作用,降低细胞中NO和TNF-α的表达量,本研究所得到的提取工艺方法简单易行、稳定可靠,可用于云南兔耳草总环烯醚萜苷的进一步研究和应用。

Abstract:

This study aims to enhance the extraction yield of total iridoid glycosides from Lagotis yunnanensis W.W.Smith and evaluate their in vitro anti-oxidant and anti-inflammatory properties.Based on the single factor experimental results, Box-Behnken response surface analysis was carried out by flash extraction method.The average extraction rate of total iridoid glycosides from L. yunnanensis was 10.56%.The total iridoid glycosides can better scour DPPH and ABTS free radicals and show anti-inflammatory effect on lipopolysaccharide-induced RAW 267.4 cells inflammation model, reduce the expression of NO and TNF-α in cells.The extraction process obtained in this study is simple, stable and reliable.It can be used for the further research and application of total iridoid glycosides of L. yunnanensis.

Key words: Lagotis yunnanensis, total iridoid glycosides, response surface method, antioxidant, anti-inflammatory
