Identification of Phytochemicals from the Water Extract of Eurycoma longifolia Roots using Solid-Liquid and Liquid-Liquid Extraction Based Fractionation Techniques.

Phytochemicals in the water extract of Eurycoma longofolia roots were identified using both solid-liquid and liquid-liquid extraction based fractionation techniques. A reversed phase C18 solid phase extraction (SPE) was used as solid-liquid extraction, whereas solvent partition was applied as liquid-liquid extraction. Total saponin was increased after fractionation.

LC-PDA-MS/MS-Based Characterization of Key Phytochemicals in Eurycoma Longifolia Roots.

The objective of the study was to fractionate the crude extract of Eurycoma longifolia (E. longifolia) roots and identify the intense peaks using HPLC-PDA-MS/MS, UPLC-MS/MS and H-NMR. Column chromatography was used to fractionate the crude extract into individual fractions using six solvent systems ranged from ethyl acetate, methanol and water in increasing polarity.
