In this study, the antioxidative activity of volatile and non‐volatile extracts from Schisandra chinensis Baill fruit was evaluated. The antioxidative activity of the sample was measured via aldehyde/carboxylic acid assay, 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) assay, and lipid/malonaldehyde assay. The sample was steam distilled under reduced pressure for extracting out the volatile components. The volatile extract was fractionated into seven fractions. The non‐volatile compounds were extracted using methanol. The antioxidative activities of 500 μg/mL of non‐volatile extract were estimated to be 76.80% by DPPH assay and 85.55% by lipid/malonaldehyde assay. Aldehyde/carboxylic acid assay revealed that fractions ⅰ and ⅱ of the volatile extract exhibited the most potent and dose‐dependent antioxidative activity. Terpenes in the volatile extract including α‐ylangene (733.512 μg/g), β‐elemene (145.690 μg/g), and bornyl acetate (321.825 μg/g) were found to contribute to the antioxidative activity.

五味子Baill果实中挥发性和非挥发性提取物的抗氧化活性

在这项研究中，五味子的挥发性和非挥发性提取物的抗氧化活性评估了保尔果。样品的抗氧化活性通过醛/羧酸测定法，2,2-二苯基-1-吡啶并乙酰肼（DPPH）测定法和脂质/丙二醛测定法进行测量。在减压下将样品蒸汽蒸馏，以提取出挥发性成分。将挥发性提取物分馏成七个馏分。非挥发性化合物使用甲醇萃取。通过DPPH测定，非挥发性提取物500μg/ mL的抗氧化活性估计为76.80％，通过脂质/丙二醛测定估计为85.55％。乙醛/羧酸测定表明，挥发性提取物的ⅰ和fraction组分表现出最有效的剂量依赖性抗氧化活性。挥发性提取物中的萜烯，包括α-ylangene（733.512μg/ g），β-elemene（145.690μg/ g）和乙酸冰片酯（321。
