Title
Supercritical CO2 and low-pressure solvent extraction of mango (Mangifera indica) leaves: Global yield, extraction kinetics, chemical composition and cost of manufacturing
Abstract

•Mango leave extracts were obtained by CO2 and percolation with ethanol.•Yield was 3.6% for supercritical process and 9.3% for percolation.•The extracts contained terpenes, flavonoids, alkaloids and antioxidant compounds.•The cost of manufacturing of the CO2 extracts was estimated as US$ 92/kg.•The cost of manufacturing of the ethanolic extracts was estimated as 32/kg.

Low-pressure solvent extraction (LPSE) and supercritical fluid extraction (SFE) were used to obtain extracts from mango (Mangifera indica) leaves. Kinetics curves were determined for both methodologies. The extracts chemical compositions and manufacturing costs were determined for both processes. Global yield isotherms for SFE process were determined at 10–40 MPa and 313–323 K. The highest yield was 2.24% at 30 MPa and 323 K; the LPSE yield (9.3%) was almost three times higher than that of SFE (3.6%). Thin layer chromatography showed that mango leaves extracts have several classes of compounds as alkaloids, flavonoids and terpenoids, recovered by both methods. The cost of manufacturing (COM) mango leaves extracts were US$ 32/kg and US$ 92/kg for LPSE and SFE, respectively.
