Assessment of size reduction and extraction methods on the yield of gallic acid from Labisia pumila leaf via microstructures analysis

The effect of size reduction and extraction methods on the gallic acid (GA) extraction yield from Labisia pumila leaf is presented. The GA extraction from a dried powdered L. pumila leaves with particle size distribution ranging from 66.66 to 1055.18 μm was performed using 10% aqueous ethanol. Three...

The GA extraction from a dried powdered L. pumila leaves with particle size distribution ranging from 66.66 to 1055.18 μm was performed using 10% aqueous ethanol.

The highest GA extraction yield at 0.32 mg/g DW was obtained using MAE method, followed by UAE (0.11 mg/g DW) and ME (0.08 mg/g DW).
