The study aimed to enhance the ultrasound-assisted extraction of polyphenols like rutin and chlorogenic acid from Hancornia speciosa fruit.
Used ultrasound-assisted extraction at 40 kHz and 145 W for 30 min at atmospheric pressure and 35 °C.
Conducted univariate experimental screening to determine optimal extraction conditions.
Measured extraction yields of total phenolic compounds, chlorogenic acid, ferulic acid, and rutin under varying conditions.
Extraction yields were 1750.16 mg GAE/100 g for total phenolic compounds, 183.86 mg/100 g for chlorogenic acid, and 2.19 mg/100 g for ferulic acid.
Rutin concentration reached 157.17 mg/100 g under specific conditions (145 W, 30 °C, 30 min).
Higher ultrasonic potency significantly improved extraction efficiency of chlorogenic acid and TPC, with no significant effect on rutin.
