A NEW NAPHTHOQUINONE ISOLATED FROM POLYGONUM MULTIFLORUM (POLYGONACEAE) Short Communication
2016
Objective: This research is mainly focused towards isolation and structural elucidation of pure compounds from the extract and fractions of Polygonum multiflorum through silica gel column chromatography. Methods: The air dried rhizomes were extracted with Me 2CO (acetone), MeOH (methanol) and H 2O (water). The Me 2CO extract was fractionated into CHCl 3 (chloroform) and residue. The chloroform-soluble portion and MeOH extract were subjected to silica gel column chromatography for the isolation of pure compounds. The isolated compounds were then determined by the use of spectroscopic analysis of HRFABMS, 1H, 13 Results: CHCl C NMR, UV and IR spectra. 3 soluble portion of Me 2 Conclusion: The obtained results will be very useful for the further evaluation various biological studies. CO and MeOH extract of P. multiflorum led to the isolation of one new naphthoquinone and eight known compounds including four anthraquinones, one naphthoquinone and two stilbenes.
