Abstract

Microdermis keayana (MK) (Pandacene) is ubiquitous to Southern Nigeria. It is used as aphrodisiac, to boost libido, induce erection, increase sperm counts and as fertility–enhancing agent. This study investigated the proximate, phytochemical and mineral compositions of MK root. The sample was obtained from Mushin herbal market in Lagos. It was identified and authenticated and cut into small pieces, sun dried for 7 days and ground to powder using Marlex Exceller grinder and stored in an airtight container. Proximate, phytochemical and mineral compositions were determined using standard protocols. Data were analyzed using student T test and were reported as means ± SEM of three determinations. The phytochemicals identified include alkaloids, cardiac glycoside, saponins, tannins, flavonoids, phlobatannins, terpenoids and sterols. Proximate analysis gave an energy value of 282 ± 0.74 g calorie, 40.84 ± 0.95% carbohydrates, 20.66 ± 0.05% proteins, 27.59 ± 0.97% fiber and 4.36 ± 0.06 of  fats. The root contains 458.8 ± 5.44 ppm of Magnesium, 216.52 ± 1.21 ppm of potassium, and 41.4 ± 0.99 ppm of calcium. Values for iron and zinc were 5.62 ± 0.48 and 28.29 ± 0.09 ppm, respectively. Lead and cadmium were not detected, an indication of safety from contamination. The high content of nutrient may account in part for the associated aphrodisiac property.

Key words: Microdermis keayana, aphrodisiac, phytochemicals, micronutrients, macronutrients.
