摘　　要：以叶面喷施不同质量浓度硼肥收获的凤丹牡丹籽为原料,采用超临界二氧化碳萃取技术制取牡丹籽油,比较叶面喷施不同质量浓度硼肥对牡丹籽油理化指标和抗氧化能力的影响。理化指标的测定结果表明,喷施硼肥对牡丹籽油碘值影响显著,对皂化值也有一定的影响,但是对酸值基本无影响;当喷施硼肥质量浓度为3 g/L时,牡丹籽油碘值达到最大值,且与对照组有显著性差异(P<0.05)。清除DPPH自由基、CUPRAC法和ABTS+法测定牡丹籽油的抗氧化活性的联合应用,比较不同质量浓度硼肥处理得到的牡丹籽油的抗氧化能力,结果显示,当喷施硼肥质量浓度为3 g/L时牡丹籽油的抗氧化能力最强。The ＇ Fengdan＇ peony seeds were harvested with foliage different mass concentrations of boronfertilizer- spraying and the peony seed oil was produced by supercritical carbon dioxide extraction. The effects of foliage different mass concentrations of boron fertilizer- spraying on physicochemical properties and antioxidant capacity of peony seed oil were compared. The results showed that the effect of foliage boron - spraying on iodine value of peony seed oil was significant. Foliage boron - spraying had a certain effect on saponification value but it had no effect on acid value. Under the condition of mass concentra- tion of boron fertilizer 3 g/L, the iodine value of peony seed oil reached the maximum, which had signifi- cant difference with control group（ P 〈0.05 ）. The antioxidant capacities of peony seed oil with different mass concentrations of boron fertilizer were compared by combined application of DPPH free radical scav- enging, CUPRAC method and ABTS ＋ method. The results indicated that under the condition of mass concentration of boron fertilizer 3 g/L, the antioxidant capacity of peony seed oil was the strongest.
