Abstract
Medicinal plants have been the cornerstone in folklore medicine practices since Neolithic, providing a wealth of magic molecules
with therapeutic properties, in the prevention and management of various health conditions. Sarcocephalus latifolius (Sm.) E.A. Bruce
(SL) is used in folkloric medicine for the treatment of a number of ailments including malaria, CVDs, cancer amongst others, however,
this assertion is not supported by empirical evidence. The study assessed the phytochemical composition and antimicrobial activities
of the solvent fractions of the fruits and stem bark of SL. These plant parts were harvested, washed, air-dried, pulverised and soaked
in 100% methanol to obtain the crude methanol extracts (CMESL and CMESBSL). These were partitioned successively between
n-hexane, chloroform, ethyl acetate and methanol to obtain their respective fractions, N-hexane (HFSL and HFSBSL), chloroform
(CFSL and CFSBSL), ethyl acetate (EFSL and EFSBSL), and the methanol (MFSL and MFSBSL).
These extracts and fractions were subjected to qualitative and quantitative assays to evaluate their phytochemical composition
and antimicrobial profile was done using typed bacteria and fungi strains. The solvent fractions obtained from the fruit and stem bark
of Sarcocephalus latifolius were evaluated for their growth-inhibitory effects against Gram-positive bacteria, Gram-negative bacteria,
and fungal species using the agar cup diffusion technique. Results of the phytochemical screening revealed that both fruit and stem
bark extracts are phytochemical rich containing flavonoids, alkaloids, saponnins among others. It was observed that both crude
and solvent fractions of the fruits and stem bark exhibited great bactericidal and fungicidal activity. For the minimum inhibition
concentration (MIC) and Minimum bactericidal/ fungicidal concentration (MBC/ MFC) results, there seemed to be a synergistic
activity between CFSL and EFSL, but CFSL revealed a higher antimicrobial potency. In conclusion, this validates the use of SL in
traditional medicine and it might contain bioactive compounds that are rich sources of phytochemicals and antimicrobial agents.
