Inhibition rates (in percentage) of the RBD:ACE2 complex of A. amazonicus. Aqueous and ethanol bark extracts (250 μg·mL−1) were assessed with the Lumit™ immunoassay (Promega). #74—Aqueous bark extract, prepared on a laboratory scale to mimic the traditional beverage; #75—Ethanol bark extract, obtained from the remaining “cake” after the aqueous extraction of the plant material which generated extract #74. #76—Ethanol bark extract, prepared by percolation; #156—Aqueous bark extract, prepared in a pilot-scale industrial plant, according to the traditional method. These data are the result of three independent technical replicates.
