Olives affected by active and damaging infestation (olive fruit fly (Rossi)) were assayed for their chemical composition. Biophenols were determined by HPLC, sterols, triterpenic dialcohols, and fatty acids by gas chromatography analysis. The acquired data were statistically analyzed. Oils produced from "Istrska belica" fruit affected by active infestation compared to the oils made from fruit affected by damaging infestation showed higher amounts of total oleuropein biofenols (377.3 versus (vs.) 106.6 mg/kg), total biophenols (755 vs. 377 mg/kg), lignans (85.3 vs. 32.9 mg/kg), the dialdehydic form of decarboxymethyl oleuropein aglycone (DMO-Agl-dA) (148.3 vs. 49.0 mg/kg), its oxidized form (DMO-Agl-dA)ox (35.2 vs. 8.5 mg/kg), the dialdehydic form of oleuropein aglycone (O-Agl-dA) (61.1 vs. 8.0 mg/kg), the dialdehydic form of ligstroside aglycone (L-Agl-dA) (63.5 vs. 28.0 mg/kg), the aldehydic form of oleuropein aglycone (O-Agl-A) (40.6 vs. 8.4 mg/kg), and lower amounts of tyrosol (Tyr) (6.0 vs. 13. 9 mg/kg) and the aldehydic form of ligstroside aglycone (L-Agl-A) (13.8 vs. 40.3 mg/kg). Higher values of stigmasterol (2.99%) and lower values of campesterol (2.25%) were determined in oils affected by damaging infestation; an increase in triterpenic dialcohols was also observed (3.04% for damaging and 1.62% for active infestation). Oils affected by damaging infestation, compared to active infestation, showed lower amounts of oleic acid (73.89 vs. 75.15%) and higher amounts of myristic (0.013 vs. 0.011%), linoleic (7.27 vs. 6.48%), and linolenic (0.74 vs. 0.61%) acids.
对受橄榄果实蝇（Rossi）活跃和破坏性侵害的橄榄进行化学成分分析。通过高效液相色谱法测定生物酚，通过气相色谱法分析甾醇、三萜二醇和脂肪酸。对获得的数据进行了统计分析。与受破坏性侵害的果实相比，受活性侵害的“伊斯特斯卡贝拉”（Istrska belica）果实产生的油显示出更高的总橄榄苦苷生物酚（377.3 与 106.6mg/kg）、总生物酚（755 与 377mg/kg）、木脂素（85.3 与 32.9mg/kg）、橄榄苦苷脱羧甲基配基二醛（DMO-Agl-dA）（148.3 与 49.0mg/kg）、其氧化形式（DMO-Agl-dA）ox（35.2 与 8.5mg/kg）、橄榄苦苷配基二醛（O-Agl-dA）（61.1 与 8.0mg/kg）、橄榄苦苷配基（L-Agl-dA）（63.5 与 28.0mg/kg）、橄榄苦苷配基二醛（O-Agl-A）（40.6 与 8.4mg/kg）的含量更高，而酪醇（Tyr）（6.0 与 13.9mg/kg）和橄榄苦苷配基二醛（L-Agl-A）（13.8 与 40.3mg/kg）的含量更低。受破坏性侵害的油中检测到豆甾醇（2.99%）含量较高，菜油甾醇（2.25%）含量较低；还观察到三萜二醇的增加（破坏性侵害为 3.04%，活性侵害为 1.62%）。与活性侵害相比，受破坏性侵害的油表现出较低的油酸（73.89 与 75.15%）和较高的肉豆蔻酸（0.013 与 0.011%）、亚油酸（7.27 与 6.48%）和亚麻酸（0.74 与 0.61%）含量。
