The present study compared the extracts obtained from the epicarp, seed, and seed tegument of avocado var. Hass with pressurized liquid extraction (PLE) and ultrasound-assisted extraction (UAE). The extracts were quantified in terms of total phenolic content (TPC) and antioxidant capacity (AC). The PLE extracts had a global yield ( ) like that obtained with UAE using ethanol (Et) as the solvent. For the TPC, the extracts obtained with both techniques showed no significant differences ( > 0.05). On the other hand, the epicarp extracts obtained with PLE had higher values for AC: 829.8 mol TE/gDe (ABTS) and 3,215.1 mol Fe/g De (FRAP), recorded for UAE/Et. The AC in the avocado residue extracted with PLE suggested a high potential for applications in food, pharmaceutical, and cosmetology products.
本研究比较了哈斯牛油果果皮、种子和种皮采用加压液体萃取（PLE）和超声辅助萃取（UAE）所得到的提取物。提取物根据总酚含量（TPC）和抗氧化能力（AC）进行定量。PLE提取物的总产率（ ）与以乙醇（Et）为溶剂采用UAE所获得的产率相似。对于TPC，两种技术所获得的提取物没有显著差异（>0.05）。另一方面，PLE所获得的果皮提取物具有更高的AC值：对于UAE/Et，ABTS法为829.8 μmol TE/gDe，FRAP法为3215.1 μmol Fe/g De。PLE提取的牛油果残渣中的AC表明其在食品、制药和美容产品中的应用具有很高的潜力。
