摘  要: 目的:为高效利用枳壳(Aurantii Fructus)中活性成分,建立测定枳壳中活性成分柚皮苷、橙皮苷和新橙皮苷的方法,并同时评价其抗氧化能力。方法:采用高效液相色谱联用1,1-二苯基-2-三硝基苯肼(HPLC-DPPH)技术,Agilent-ZORBAX SB-C18色谱柱(150 mm×4.6 mm,5μm),流动相为0.04%磷酸水(A)-乙腈(B),采用梯度洗脱程序,检测波长:283 nm,柱温:25℃,流速:0.8 m L·min-1。结果:柚皮苷、橙皮苷及新橙皮苷质量分数分别为52.64、2.41、34.27 mg·g-1;抗氧化能力贡献率(AA*):柚皮苷(58.9%)>新橙皮苷(38.3%)>橙皮苷(2.8%),DPPH自由基清除率(AA**):柚皮苷(47.8%)>橙皮苷(38.1%)>新橙皮苷(36.2%)。结论:本文通过建立HPLC-DPPH法对枳壳抗氧化活性成分进行测定和评价,为开发利用枳壳中抗氧化活性成分提供一种新思路。 Objective:In order to utilize the active ingredients effectively in Aurantii Fructus,a method of determination and evaluation the antioxidant capacity of naringin,hesperidin and neohesperidin simultaneously in Aurantii Fructus was established with high performance liquid chromatography combined with 1,1-diphenyl-2-picrylhydrazyl (HPLC-DPPH) technique.Methods:The determination conditions were as follows:HPLC separation was carried out with an Agilent-ZORBAX SB-C18 column (150 mm×4.6 mm,5 μm) using 0.04% phosphoric acid (A)-acetonitrile(B) /[0-5 min,12%-20% B;5-15 min,20%-25% B;15-25 min,25%-12% B;5-30 min,12% B/] as mobile phase at a flow rate of 0.8 mL·min-1.The detection wavelength was 283 nm and the column temperature was maintained at 25 ℃.Results:The content of naringin,hesperidin and neohesperidin in Aurantii Fructus was 52.64,2.41,34.27 mg·g-1 separately.The contribution rate of total antioxidant capacity(AA*) was naringin (58.9%) 〉 neohesperidin (38.3%) 〉 hesperidin(2.8%),and the DPPH free radical scavenging rate (AA**) was naringin(47.8%) 〉 hesperidin (38.1%) 〉 neohesperidin (36.2%).Conclusion:HPLC-DPPH method was efficiently established for the determination and evaluation of the antioxidant compounds of Aurantii Fructus, and this method could provide a new idea for the research and utilization of Aurantii Fructus.
