益智是一种名贵中药，从中提取得到的益智油具有抗氧化作用。以石油醚作为提取溶剂，采用超声波辅助提取法得到益智油，DPPH（二苯代苦肼基自由基）法测定其抗氧化能力，气相色谱-质谱联用仪（GC-MS）对其进行成分分析。以得油率为指标，超声时间、温度、料液比进行单因素实验，再运用正交设计对其提取条件进行优化。结果表明，超声法提取益智油的最佳条件为超声时间75 min、温度35℃、料液比4.5 mL/g，在此条件下，得油率可达3.63%；经抗氧化能力测定，超声波法提取的益智油具有较好的抗氧化能力；经成分分析，益智油中主要含萜类等抗氧化活性成分。

Alpinia oxyphylla is a valuable medicine, and the oil extracted from it has antioxidant properties. Petroleum ether was used as extraction solvent to extract oil from Alpinia oxyphylla by ultrasound-assisted method as well as the antioxidant capacity of the oil was tested by DPPH. Ingredients were performed by gas chromatography-mass spectrometry analysis (GC-MS). Using the extracted rate of oil as an index, extraction time and temperature, material/liquid ratio were investigated with single-factor test, then its optimum extraction conditions were optimized by orthogonal designs. The results showed that the optimum conditions for ultrasound-assisted extraction were extraction time of 75 min , extraction temperature of 35 ℃,material/liquid ratio of 4.5 mL/g. Under these conditions, the extracted rate was up to 3.63%. According to tests, the oil showed strong antioxidant capacity. By composition analysis, the oil contains terpenoids and other active ingredients.
