The extraction of litchi ( Sonn.) and oat ( L.) seeds were investigated using -butane as pressurized solvent by evaluating the effect of pressure in the range of 7-100 bar and temperature from 25 to 70 °C on the extract yield and chemical composition together with the antioxidant activity of the extracts obtained. It was experimentally observed extraction yields for both seeds up to ~3.5 wt%, with a total phenolic content around 126.4 mg GAE/100 g of extract, and an antioxidant activity up to 78.36%. Oat seeds extract presented higher values of these parameters evaluated compared to litchi extract. Based on the results found, it seems that -butane may be a promising solvent to conventional extraction methods, as mild operating conditions and eco-friendly solvent can be used to provide good results without any residues in the final product.
通过评估7至100巴的压力范围和25至70°C的温度对提取物产率、化学成分以及所获提取物抗氧化活性的影响，研究了以正丁烷作为加压溶剂提取荔枝（Sonn.）和燕麦（L.）种子的情况。实验观察到两种种子的提取产率均高达约3.5 wt%，总酚含量约为126.4 mg GAE/100 g提取物，抗氧化活性高达78.36%。与荔枝提取物相比，燕麦种子提取物的这些评估参数值更高。基于所发现的结果，正丁烷似乎可能是传统提取方法的一种有前景的溶剂，因为可以使用温和的操作条件和环保型溶剂来获得良好的结果，且最终产品无任何残留。
