摘要: 通过双相酸水解法优化山奈酚提取条件,结合高效液相色谱(HPLC)法,通过单因素实验考察酸浓度、提取时间和固液比对山奈酚提取率的影响,并利用响应面Box-Behnken实验优化提取山奈酚的最佳工艺. 实验结果表明:最佳提取条件的盐酸浓度为6.1×10-2 mmol/L,提取时间为12.87 min, 固液比为1∶137.46, 提取率达1.11%; 山奈酚具有一定的抗氧化作用, 对超氧自由基(·O2-) 和1,1-二苯基-2-三硝基苯肼( DPPH·)均有一定的清除能力, 尤其对DPPH·的清除能力更强, 且清除能力随浓度的升高而提高.

Abstract: The extraction conditions of kaempferol were optimized by a two-phase acid hydrolysis method,  and the effects of acid concentration,  extraction time and solid-liquid ratio on the extraction yield of kaempferol were investigated by a single factor experiment combined with high performance liquid chromatography (HPLC). The  response surface Box-Behnken experiment was used to optimize the extraction process of kaempferol. The experimental results show that the optimum extraction conditions are  the concentration of hydrochloric acid of 6.1×10-2 mmol/L,  the extraction time of 12.87 min,  the solid-liquid  ratio of 1∶137.46,  and the extraction yield is 1.11%. Kaempferol has a certain antioxidant effect,  and has certain scavenging ability on superoxide free radical (·O2-) and 1,1-diphenyl-2-picrylhydrazyl radical 2,2-diphenyl-1-(2,4,6-trinitrophenyl)hydrazyl (DPPH·),  especially on DPPH·,  and the scavenging ability  increases with the increase of concentration.
