| 旨在为甘肃陇南橄榄油的质量评价和油橄榄鲜果采收时间提供指导，探究了不同品种初榨橄榄油（VOO）中多酚类化合物（PPs）随油橄榄果生长发育的累积变化。以甘肃陇南不同成熟度的8个品种油橄榄鲜果为原料，采用压榨法获得VOO，利用反相高效液相色谱法同时测定VOO中的9种PPs含量。结果表明：VOO中总多酚的含量主要由酪醇和橄榄苦苷决定，橄榄苦苷是含量最高的PPs，且其含量随油橄榄果成熟度指数（MI）变化最明显；VOO中木犀草苷含量均较低，阿魏酸和芹菜素仅在个别品种中检测到，芦丁在所测油品中均未检测到；‘阿斯’‘鄂植8号’‘中山24号’和‘佛奥’4个品种VOO的PPs评估数据表现良好，分别在MI为0～1.0、2.0～4.0、0～2.0和5.0～7.0表现最佳，建议这4个品种油橄榄鲜果的采收时间分别为9月下旬、11月上旬、9月下旬至10月上旬以及11月下旬，而‘切姆拉尔’VOO在PPs种类和总含量等评估数据中表现不佳。综上，可以依据不同MI的油橄榄鲜果制备的VOO中多酚含量，尤其是酪醇和橄榄苦苷含量，确定不同品种油橄榄鲜果的采收时间，并进行VOO的品质评价。 |

| The cumulative changes in the contents of polyphenols (PPs) in virgin olive oils (VOO) with the growth and development of olive fruits were investigated so as to provide the guidance for olive oil quality evaluation and fresh olive fruits harvest. The VOO were extracted by pressing from 8 varieties of fresh olive fruits with different maturity in Longnan, Gansu Province. The contents of 9 kinds of PPs in VOO were simultaneously determined by reversed phase-high performance liquid chromatography (RP-HPLC). The results showed that the content of total polyphenols in VOO was mainly determined by tyrosol and oleuropein. The oleuropein content was the highest, and its content changed most obviously with olive maturity index (MI). Luteolin content in VOO was lower, and ferulic acid and apigenin were detected only in a few varieties, while rutin was not detected in all detected VOO. The evaluation data of PPs in VOO extracted from the fresh olive fruits of Ascolana Tenera, Ezhi-8, Zhongshan-24 and Frantoio were good, with the best performance at MI of 0-1.0, 2.0-4.0, 0-2.0 and 5.0-7.0, respectively. These four olive fruits varieties were suggested to be harvested in late September, early November, late September to early October and late November respectively. While the comprehensive data of Chemlal performed poorly combined in terms of polyphenols species and total content. In conclusion, the harvest time of fresh olive fruits of different olive varieties can be determined according to the content of olive polyphenols especially tyrosol and oleuropein in different MI, and the quality of olive oil can also be evaluated by the contents of polyphenols. |
