GC-MS analysis of phytocomponents in the ethanol extract of Polygonum chinense L.
BACKGROUND
The presence of diverse secondary metabolites has been reported from species of the genus Polygonum. However, there has been not much information available on phytochemical components and biological activity in the whole plant ethanol extract of Polygonum chinense L.


OBJECTIVE
This study was designed to determine the phytocomponents in the whole plant ethanol extract of P. chinense.


METHODS
GC-MS analysis of the whole plant ethanol extract of P. chinense was performed using a Perkin-Elmer GC Clarus 500 system comprising an AOC-20i auto-sampler and a gas chromatograph interfaced to a mass spectrometer (GC-MS).


RESULTS
This investigation was carried out to determine the possible chemical components from P. chinense by GC-MS. This analysis revealed that the ethanol extract of P. chinense (whole plant) contained mainly a triterpene compound-squalene (47.01%), and a plasticizer compound-1,2-benzenedicarboxylic acid, mono[2-ethylhexyl]ester (40.30%). All identified compounds were, generally, reported as having antimicrobial activity. In addition, the squalene compound also having anti-cancer, anti-oxidant, anti-tumor, chemo-preventive, pesticidal and sun-screen properties, while the plasticizer compound -1,2-benzenedicarboxylic acid, mono[2-ethylhexyl] ester reported to have anti-oxidant and anti-inflammatory properties. No activity was reported in the alcoholic compound-4-hexene-1-ol, 5-methyl-2-(1-methylethanyl)-acetate-(R)-.


CONCLUSIONS
From the results, it is evident that P. chinense contains various bioactive compounds and is recommended as a plant of phytopharmaceutical importance.
