This study aimed to determine the phenolic content and biological activity of ethanolic extracts from iraca waste (Carludovica palmata Ruiz & Pav) obtained through ultrasound-assisted extraction (UAE). The effects of temperature (30 °C and 60 °C), amplitude (20%, 40%, and 60%), and extraction time (2, 10, and 20 min) on the total phenolic content (TPC) and antioxidant activity of the extracts were evaluated. Soxhlet extraction and low-pressure solvent extraction (LPSE) were conducted to compare their results with that of UAE. Chlorogenic and gallic acids were more abundant than other phenolic compounds (PC) in the extracts, with concentrations of 106.78 and 88.75 mg 10 g⁻¹, respectively. Higher values of TPC (244.69 mg 100 g⁻¹) and AC (69.23% ± 4.60 inhibition) were obtained when the extraction process was performed at 60 °C, 10 min, and 40% amplitude. The antimicrobial activity of the extract obtained under the best process conditions was evaluated. Antimicrobial activity against Escherichia coli and Staphylococcus aureus was observed when in concentrations of 50% w/v and 20% w/v, respectively. The PC present in the extracts and their biological activity were affected by the extraction parameters. Results show that PC from iraca waste infructescence can be extracted through UAE using shorter extraction times to preserve the integrity of the compounds.

这项研究旨在确定通过超声波辅助提取（UAE）获得的伊拉卡垃圾（棕榈果Carludovica palmata Ruiz＆Pav）中乙醇提取物的酚含量和生物活性。温度（30°C和60°C），振幅（20％，40％和60％）和提取时间（2、10和20分钟）对总酚含量（TPC）和抗氧化活性的影响提取物的含量进行了评估。进行了索氏提取和低压溶剂提取（LPSE），以将其结果与阿联酋的结果进行比较。提取物中的绿原酸和没食子酸含量比其他酚类化合物（PC）丰富，分别为106.78和88.75 mg 10 g ^-1。TPC的较高值（244.69 mg 100 g ^-1）和AC（69.23％±4.60抑制）在60°C，10分钟和40％振幅下进行提取时获得。评价了在最佳工艺条件下获得的提取物的抗菌活性。当分别以50％w / v和20％w / v的浓度观察到对大肠杆菌和金黄色葡萄球菌的抗菌活性。提取物中存在的PC及其生物学活性受提取参数的影响。结果表明，可以用较短的萃取时间通过阿联酋萃取来自伊拉卡草废渣的PC，以保持化合物的完整性。
