Preliminary Phytochemical Screening of Plumbagozeylanica L. Roots and Its Aphrodisiac Effect in Male Rats
Asian Journal of Applied Chemistry Research,
Aim: To perform phytochemical screening of Plumbago zeylanica L. root extracts and assess the claim of its use in traditional management of erectile dysfunction in Uganda through evaluation of the aphrodisiac effect of its aqueous extracts in male Wistar rats.
Study Design: This study employed both qualitative and quantitative research designs.
Place and Duration of Study: All research work were performed at the Department of Biological Sciences, Gulu University, Gulu, Uganda between August 2019 and December 2019.
Methodology: Classical phytochemical screening of aqueous and methanolic extracts of Plumbago zeylanica roots were performed following standard methods. Aqueous extracts were administered to Male Wistar rats and the effect of the extracts on the mounting and intromission frequencies were determined.
Results: Glycosides, phenols, saponins, quinones, terpenoids and steroids were present in both methanolic and aqueous extracts. Alkaloids were present in methanolic extracts only while tannins and phlobatannins were only present in aqueous extracts. Flavonoids, coumarins and anthraquinones were not detected in both extracts. Aqueous root extracts of Plumbago zeylanica produced pro-sexual stimulatory effects in male rats when administered at 150, 300 and 450 mg/kg body weight.
Conclusion: The results support the use of Plumbago zeylanicaroots by indigenous people in Uganda to increase libido, treat premature ejaculation and erectile dysfunction. The extracts had low sexual enhancement in sexually inexperienced male rats and therefore, further studies using experienced animal models are needed to better apprehend the prosexual effects of P. zeylanica roots. The toxicity of the extracts as well as structural elucidation and pharmacological evaluation of the responsible bioactive compounds merit further studies.
