Zusammenfassung: | Polygonum barbatum (L.) Hara var. barbata (Polygonaceae), commonly known as 'bekhanjabaj', is a Bangladeshi perennial herb. A combination of the normal phase column chromatography and preparative thin layer chromatography on silica gel afforded sitosterone (1) from the petroleum ether fraction, and viscozulenic acid (2) and acetophenone (3) from the chloroform fraction of the methanol extract of the aerial parts of this plant . The free-radical-scavenging properties the isolated compounds 1-3 were evaluated by the 2,2-diphenyl-1-picryl-hydrazyl (DPPH) assay. |
