摘要：研究了中国、西班牙、意大利和希腊4个国家的40个商业特级初榨橄榄油(EVOO)的酸值、过氧化值、在232和270 nm处紫外吸光度(A_(232)和A_(270))及主要化学成分,测定了不同国家EVOO总多酚组分的抗氧化活性,并对总多酚含量和半数抑制质量浓度(IC_(50)值)做了相关性分析。研究结果表明:所有样品酸值(<1.60 mg/g)和过氧化值(<10 mmol/kg)的合格率为97.5%,A_(232)(1.02~1.80)和A_(270)(0.05~0.13)指标的合格率为100%。4个国家EVOO样品中总多酚含量差异显著,中国的EVOO样品中羟基酪醇、酪醇、刺激醛和橄榄裂环烯醚萜的质量分数分别为(11.66±2.50)、(9.61±2.65)、(273.63±43.09)和(332.04±49.08)mg/kg,均显著高于其它3个国家的EVOO样品(p<0.05);主要脂肪酸、甾醇和生育酚的含量无显著性差异。此外,EVOO多酚组分的DPPH·、·ABTS^(+)清除力和β-胡萝卜素漂白实验结果显示IC_(50)值变化范围分别为(74.1±3.0)~(560.0±15.0)、(71.9±3.0)~(701.7±12.0)和(68.0±2.3)~(617.0±17.0)g/L,表明EVOO总多酚组分具有良好的抗氧化活性,相关性分析表明样品中总多酚的含量与其IC_(50)值呈显著负相关的关系(p<0.05),相关性方程斜率分别为-1.665,-1.931和-1.792。
The acid value,peroxide value,UV absorbance at 232 and 270 nm(A_(232)和A_(270))and main chemical components of 40 commercial extra-virgin olive oil(EVOO)samples from China,Spain,Italy and Greece were studied.The antioxidant activities of polyphenol extracts from different countries were determined,and the correlation between total polyphenol content and half inhibitory mass concentration(IC_(50))value was analyzed.The results showed that the qualification rates for acid value(<1.60 mg/g)and peroxide value(<10 mmol/kg)of these 40 samples were 97.5%,while whose for A_(232)(1.02-1.80)and A_(270)(0.05-0.13)indexes reached 100%.The total polyphenol contents in EVOO samples from four countries differed significantly,with the concentrations of hydroxyltyrosol,tyrosol,oleocantthal and oleacein in Chinese EVOO samples being(11.66±2.50),(9.61±2.65),(273.63±43.09),and(332.04±49.08)mg/kg,respectively,significantly higher than those in EVOO samples from the other three countries(p<0.05).No significant differences were observed in the contents of major fatty acids,sterols,and tocopherols.In addition,three antioxidant assays(DPPH·、·ABTS^(+),andβ-carotene bleaching)consistently demonstrated strong antioxidant activity in EVOO.The ranges of IC_(50)were(74.1±3.0)to(560.0±15.0),(71.9±3.0)to(701.7±12.0),and(68.0±2.3)to(617.0±17.0)g/L.Correlation analysis showed a negative relationship between total polyphenol content and IC_(50)values(an indicator of antioxidant capacity)(p<0.05),with the slopes of the correlation equation were-1.665,-1.931 and-1.792.
