- •
Phyllanthus amarus extracts were obtained by ultrasound-assisted extraction and pressurized liquid extraction.
- •
Ultrasound-assisted extraction and pressurized liquid extraction yielded higher gallic acid content compared to conventional extraction.
- •
The extracts were analyzed by ultra-performance liquid chromatography/quadrupole time of flight mass spectrometry.
- •
Hydrolysable tannins, flavonoids, and lignans were the main compounds detected.
