Biological Activities

Grewia bicolor is a versatile plant species that demonstrates a wide array of therapeutic properties within traditional medicine. Scientific screenings have confirmed its strong anthelmintic activity, particularly against resistant strains of nematodes. Furthermore, the plant exhibits significant antioxidant potential due to its rich concentration of bioactive metabolites like phenols and carotenoids. Its medicinal value is further enhanced by proven antimicrobial properties against both Gram-positive and Gram-negative organisms. Finally, traditional Sudanese practices utilize the plant as a tranquilizer, highlighting its complex pharmacological profile.

Compounds

Conditions

Grewia bicolor serves as a significant medicinal plant used by Bapedi traditional healers to treat diarrhoea in the Limpopo Province. This species also demonstrates strong anthelmintic activity, making it a candidate for treating intestinal infections caused by parasitic worms. Beyond these uses, pharmacological studies have shown that an ethanol extract of its roots can significantly increase resorption in rats during early pregnancy. These diverse therapeutic roles highlight the plant's multifaceted impact on gastrointestinal and reproductive health. Consequently, Grewia bicolor remains a vital component in both traditional healthcare and pharmacological research.

Preparations

Grewia bicolor is prepared as a methanol extract to yield beta-sitosterol-glucoside and specific alkaloids like harman, 6-methoxyharman, and 6-hydroxyharman. This methanol extract further demonstrates biological activity against both gram-positive and gram-negative organisms. Additionally, Grewia bicolor is prepared as a petroleum ether extract to isolate various chemical compounds. This particular petroleum ether extract affords beta-sitosterol, beta-sitosterol- and triterpene esters, as well as the triterpenes lupeol and betulin. Both extraction methods serve to identify the distinct phytochemical profiles present within the plant.

Parts used

Grewia bicolor is a plant species that contains a biologically active root component used in various pharmacological studies. Research indicates that an ethanol extract derived from these roots can influence reproductive outcomes in animal models. Specifically, administration during pregnancy has been shown to significantly increase resorption rates in rats. The study also identified an active peptide within the root that exerts a serotonin-like effect on the uterus and intestinal tissue. These physiological responses can be blocked by specific inhibitors, highlighting the complex chemical relationship between the plant's roots and biological systems.
