Ultrasound-assisted extraction was employed to extract polysaccharides from longan seed (LSP), with aids of a Box-Behnken statistical design to investigate the effects of ultrasonic power, time and liquid/solid ratio on the extraction recovery of the LSP. The structural analysis indicated that arabinose, galactose, glucose and mannose were major components of LSP, with →6)-Gal-(→1, Glc-(→1 and →6)-Glc-(1→ glycosidic linkages. In an in vitro antioxidant activity of the 1,1-diphenyl-2-picryldydrazyl radical-scavenging assay, LSP exhibited a dose-dependent property within the concentration range tested.
超声辅助提取法被用于从龙眼籽（LSP）中提取多糖，采用 Box-Behnken 统计设计来考察超声功率、时间和液固比对 LSP 提取回收率的影响。结构分析表明，LSP 的主要成分是阿拉伯糖、半乳糖、葡萄糖和甘露糖，具有→6)-Gal-(→1、Glc-(→1 和→6)-Glc-(1→糖苷键。在 1,1-二苯基-2-苦基肼自由基清除试验的体外抗氧化活性中，LSP 在测试浓度范围内表现出剂量依赖性。
