Anti-inflammatory effects of medicinal plants mixture used by Bedouin people in Saudi Arabia
Due to toxic and adverse side effects of synthetic drugs, traditional herbal medicine has the potential as a source of new bioactive molecules. That is why we investigated this research, searching new anti-inflammatory drugs from plants growing around us. The anti-inflammatory effect of the mixture of different plants used in traditional medicine (Alkanna tinctoria, Rubia tinctorum and Artemisia herba alba) were studied using carrageenan-induced paw edema (oil mixture extract 100 mg/kg and 200 mg/kg). These material reduces carrageenan-induced inflammation in rats and shows inhibition after 4 h especially at a concentration 200 mg/kg. Oil mixture extract were investigated by capillary GC and GC–MS in combination with retention indices revealed the presence of about 17 compounds: artemisol, epiglobulol and α-bisabolol are the main constituents as well as volatile oil and other triterpenes: taraxasterol, stigmasterol, ursan-12-ene, olean-12-ene, betulin, germincol, lupeol acetate and lupeol. Other heterocyclic compounds: moropholine and piperidinol were also identified.
