Biological Activities

Polygonum aviculare stands out as a significant medicinal plant when evaluating natural sources for treating rheumatic diseases. During a systematic screening of fifty different plants, this species demonstrated exceptional antioxidant capacities through both FRAP and TEAC assays. The study revealed that the plant possesses strong free radical scavenging activity and potent oxidant reducing power. This high level of activity is closely linked to its substantial total phenolic content, which serves as a primary driver of its biological benefits. Consequently, Polygonum aviculare is identified as a rich and promising potential source of natural antioxidants for therapeutic use.

Compounds

Polygonum aviculare serves as a rich natural source for various bioactive chemical compounds. Recent investigations into its acetone extracts have led to the successful isolation of several significant substances. Notably, research confirms that this plant contains the known compound oleanolic acid. Furthermore, chemical analysis has also identified the presence of sitosterol within the same specimen. These findings highlight the diverse phytochemical profile found within Polygonum aviculare.

Conditions

Polygonum aviculare is utilized in traditional folk medicine to treat various inflammatory diseases, specifically including arthritis and airway inflammation. In studies involving liver fibrosis, the plant's methanol extract has demonstrated the ability to significantly reduce serum levels of alkaline phosphatase (ALP). Furthermore, this plant effectively lowers alanine transaminase (ALT) levels in subjects experiencing liver damage. These combined effects highlight the medicinal importance of Polygonum aviculare in managing both systemic inflammation and specific biochemical markers of liver health.

Preparations

Polygonum aviculare is prepared as acetone extracts to isolate compounds such as 6-methoxyplumbagin. This plant is also processed into hexane extracts and n-BuOH extracts, both of which have demonstrated distinctive vasorelaxant activity in studies involving isolated rat aorta. Additionally, the methanol extract of Polygonum aviculare has been shown to exhibit significant antifibrotic effects in rats with induced liver fibrosis. Finally, water extracts of the plant have been identified as active in assays measuring the inhibition of prostaglandin biosynthesis and platelet activating factor-induced exocytosis.
