Statement of the problem: Traditionally, male inhabitants of East African coastal regions with penile dysfunction, premature ejaculation, low libido prefer using panicum maximum (mbayaya) as ethnomedicine rather than the modern synthesized drugs. This motivates us to determine the bioactive sexual ingredients from the plant extract and its efficacy.

Methodology and theoretical considerations: Samples were collected from Upenja north regions of Zanzibar where it grows naturally. The bioactive ingredients from the plant sample were extracted using the standard procedures and the standard solvents for extraction techniques. The presences of bioactive substances were qualitatively determined with the help of Classical, Hyphenated Chromatographic and Spectroscopic instrumental techniques.  The preliminary phytochemical analyses for the relevant phytochemical constituents were assayed qualitatively using the standard methods to ascertain its medicinal values and safeness. The medicinal activity of this extract(considering the traditional dose response ratio)  to be tested on rats by monitoring and measuring body temperature using cyrogen probe machine, evaluating number of mounts (no vaginal penetration), intromissions (vaginal penetration) and ejaculations.

Findings and recommendations: This study reveals the presence of major bioactive sexual ingredients thus ascertaining the ethnopharmacological use of the plant, however comparative analytical studies and evaluation of more ingredients from panicum maximum is recommended.
