范文编号:ZY058 范文字数:10950,页数:39 摘 要:本范文主要研究在超声辅助下的水提白花前胡中,花椒毒素的最佳提取工艺。方法:以白花前胡中花椒毒素提取量的吸光值为指标,在单因素试验的基础上,采用正交试验设计法对白花前胡的超声辅助水提工艺进行优选,考察超声提取温度、超声提取功率、超声提取时间和料液比对花椒毒素提取量吸光值的影响。结果:超声辅助水提白花前胡中花椒毒素的最佳工艺为:超声温度为50℃,超声功率为176W,超声提取时间为40min,料液比为1:20。结论:所确定的最佳提取工艺可合理提取白花前胡中的活性成分。 关键词:白花前胡;花椒毒素;8-甲氧基补骨脂;超声;水提 Abstract: This paper mainly studies in the ultrasound-assisted water extraction process of Xanthotoxin from Peucedanum praeruptorum Dumn.With the absorbency of Peucedanum praeruptorum Dumn for index,to xanthotoxin amount of a pigment absorbance value of the target in single-factor test, based on the orthogonal design method of ultrasonic assisted xanthotoxin water extraction process was optimized to investigate ultrasonic extraction temperature, extraction power, extraction time and solid to liquid ratio on the extraction of xanthotoxin component of absorbency. The ultrasound-assisted water extraction and xanthotoxin in a prime optimum technology for: ultrasonic temperature is 50 ℃, ultrasonic power is 176W, extraction time of 40min, solid to liquid ratio of 1:20. The optimized method can be applied for the extraction of active components in roots of Peucedanum praeruptorum Dunn. Keywords:Peucedanum praeruptorum Dumn;xanthotoxin;8-methoxypsoralen;ultrasound-assisted water extraction
