  • Abstract:

Hibiscus physaloides, a woody medicinal herb of the family Malvaceae used in treating parasitic infections, arthritis and pains was analyzed for its proximate and mineral composition in this study. The leaves were collected from the herbal garden of Biomedicinal Research Centre, Forestry Research Institute of Nigeria. They were washed, air dried and homogenized. Proximate and mineral compositions were determined using standard analytical procedures carried out in the laboratory. The proximate composition showed that the leaves are rich in carbohydrate (73.84 plus or minus 0.09%), moderate amounts of crude fibre (11.5 plus or minus 0.05%) and ash (7.49 plus or minus 0.21%) were detected. Crude fat, crude protein and moisture were also present at considerable amounts of 0.6 plus or minus 0.02%, 2.77 plus or minus 0.04% and 3.8 plus or minus 0.11% respectively. For mineral elements, K, Ca, Fe, Mg, Na, and P were present at varying amounts of 5.90 plus or minus 0.03 mg/g, 2.94 plus or minus 0.002 mg/g, 2.05 plus or minus 0.005 mg/g, 1.44 plus or minus 0.003 mg/g, 1.30 plus or minus 0.06 mg/g and 1.20 plus or minus 0.02 mg/g respectively. Mn, Zn and Cu had relatively low concentrations of 0.1 plus or minus 0.00 mg/g, 0.08 plus or minus 0.001mg/g and 0.02 plus or minus 0.001mg/g respectively. Findings from this study also showed that Hibiscus physaloidesleaves have several nutrients like other species in its genus. Hence, Hibiscus physaloides leaves are repositories of nutrients which can be exploited for human and animal benefits. Keywords: Malvaceae, medicinal plant, proximate analysis, mineral elements
