The aim of our study was to examine the economics of ultrasound-assisted extraction (UAE) of phenolic compounds from iraca infructescence. The effects of temperature, amplitude, and extraction time on the global extraction yield (GEY) and total phenolic content of the extracts from the iraca infructescence were evaluated. An evaluation of the economics of the extraction process was conducted. The operational parameters evaluated were temperature (30 °C and 60 °C), extraction time (2, 10, and 20 min), and amplitude (20%, 40%, and 60%). Soxhlet extraction and low-pressure solvent extraction (LPSE) were conducted to compare their results with those of UAE. GEYs and the total phenolic contents from 10.8% to 34.3% and from 60.4 to 368.6 mg g−1, respectively, were obtained. The optimal operating parameters were determined to be 60 °C, 20 min, and 40% or 60% amplitude. Apigenin, chlorogenic acid, and hesperetin were identified by liquid chromatography–mass spectrometry in the ethanolic extracts. The cost of manufacturing (COM) decreased from US$ 456.04 kg−1 to US$ 93.43 kg−1 when the capacity of the two-extractor system increased from 5 L to 500 L. The results show that UAE is a feasible technique by which to valorize the iraca infructescence.
