闪式与回流提取美洲大蠊总氨基酸的工艺比较

Comparion of Smashing and Reflux Extraction Process for Total Amino Acid in Periplaneta americana

目的:比较闪式与回流提取美洲大蠊总氨基酸的工艺。方法:以总氨基酸提取率为指标,采用紫外分光光度法测定指标成分含量,考察闪式与回流提取对美洲大蠊总氨基酸提取工艺的影响。结果:采用闪式提取总氨基酸的含量与回流提取基本一致。结论:美洲大蠊总氨基酸采用闪式提取效率高、省时、节能,可推广用于动物类药材的提取。

Objective： To compare smashing and reflux extraction of total amino acid in Periplaneta americana. Method ： With extraction rate of total amino acid as index, which w.as determined by UV-vis, effect of smashing and reflux extraction on total amino acid in P. americana was investigated. Result： The content of total amino acid in P. americana of smashing extraction was basically the same with reflux extraction. Conclusion： Smashing extraction method for total amino acid in P. americana could save time, working and energy, it should be widely used in extraction of animal medicine.
