Biological Activities

Compounds

Arctostaphylos uva-ursi stands out among tested medicinal extracts for its remarkable capacity to scavenge DPPH radicals and chelate iron. This potent biological activity is largely attributed to the high levels of polyphenols found within the plant. These polyphenol-rich compounds play a critical role in modulating the susceptibility of Escherichia coli to various antibiotics. Research indicates a strong correlation between this polyphenol content and the extract's ability to protect bacteria against peroxide stress. Ultimately, the antioxidant and prooxidant properties of these polyphenols appear to drive the complex mechanisms that influence bacterial response to antibiotic treatment.

Conditions

Arctostaphylos uva-ursi is traditionally used to treat urinary tract infections due to bioactive compounds like arbutin that possess anti-adhesive properties. This plant also demonstrates antimicrobial activity against S. aureus, showing both bacteriostatic and bacteriocidal effects. In certain contexts, extracts of the plant have been shown to stimulate biofilm formation in Escherichia coli. Furthermore, the roots of Arctostaphylos uva-ursi exhibit high bioaccumulation of heavy metals, specifically accumulating Cu and Zn. These diverse biological and chemical interactions highlight the complex functional profile of the species.

Preparations

Arctostaphylos uva-ursi is prepared as Folium uvae-ursi, a drug used in the pharmaceutical industry for producing medicinal teas with disinfective effects on the urinary tract. This plant is also a component of the traditional Mongolian prescription known as Gurgem-7. Research further demonstrates that Arctostaphylos uva-ursi is prepared as an aqueous extract to study its inhibitory effects on myrosinase activity. Additionally, the plant is processed as a water extract to investigate its impact on the decomposition of glucosinolates. Finally, Arctostaphylos uva-ursi is prepared as various extracts that exhibit significant antioxidant and prooxidant properties when interacting with bacteria.

Parts used

Arctostaphylos uva-ursi serves as a significant subject in studies regarding heavy metal bioaccumulation in medicinal plants. Specifically, the roots of this species demonstrate a high capacity for accumulating metals such as copper and zinc from contaminated environments. The study found that the roots of Arctostaphylos uva-ursi achieved bioaccumulation factors of 30.44 for copper and 20.59 for zinc. Such high levels of metal uptake highlight the risks associated with using plants irrigated with contaminated drain water for medicinal purposes. Consequently, these findings emphasize the necessity of monitoring plant parts like roots to ensure human safety and mitigate health risks.
