This work studies the oil extraction and recovery of bioactive compounds from Brazilian and Mexican avocado seeds and peels of Hass cultivar using Soxhlet (SE) with hexane, ethanol, and ethyl acetate as solvents; and supercritical carbon dioxide (scCO₂) with ethanol and ethyl acetate as cosolvents. Also, the fatty acids (FAs) profile, total phenolic content (TPC), and antioxidant activity (AA) in avocado seeds measured. Finally, the dynamic extraction curves of scCO₂ were modeled with a multi-way partial least squares regression (MPLSR).

The highest extraction yields were observed when ethanol is used as solvent in SE (up to 14 wt%) and as cosolvent in scCO₂ (up to 6.9 wt%). TPC was higher in SFE of avocado seeds, while higher values of AA were obtained using SE. MPLSR model obtained for the scCO₂ extraction showed an average absolute deviation below 0.5 wt% for 360 measurements using only eight factors.

这项工作使用索氏提取法（SE），以己烷，乙醇和乙酸乙酯为溶剂，研究了巴西和墨西哥鳄梨种子和Hass品种果皮中油的提取和生物活性化合物的回收；以及以乙醇和乙酸乙酯为助溶剂的超临界二氧化碳（scCO ₂）。此外，还测量了鳄梨种子中的脂肪酸（FAs），总酚含量（TPC）和抗氧化活性（AA）。最后，使用多向偏最小二乘回归（MPLSR）对scCO ₂的动态提取曲线进行建模。

当乙醇用作SE中的溶剂（最高14 wt％）和scCO _2中的助溶剂（最高6.9 wt％）时，观察到最高提取率。鳄梨种子的SFE中TPC较高，而使用SE获得的AA值较高。仅使用八个因素进行360次测量时，用于scCO ₂提取的MPLSR模型显示平均绝对偏差低于0.5 wt％。
