Phytochemical, Minerals and Antimicrobial Evaluation of Trianthema portulacastrum (aizoaceae) Leaf extract

Abstract

The leaf extracts of the plant was analyzed for its phytochemical, mineral and antimicrobial activities using the standard method. The Phytochemical constituent revealed the presence of tannins in all the solvent system used for extraction. Alkaloids and phenol were present in dichloromethane, ethyl acetate, methanol and aqueous extract but absent in ethanol extract. Flavonoids, cardiac glycoside and saponins were present in aqueous and ethanol extract. Terpenoids was absent in aqueous but present in the other solvent used. The proximate composition revealed carbohydrate has the highest percentage content of 21.24%, protein: 21.10%, Fibre: 18.40%, Ash: 17.82% while lipid and moisture content are 11.94% and 9.5% respectively.  The mineral composition in the leaf showed the contents (mg/g) as in order of Ca: 7.3303mg/g>K: 2.3297mg/g>Na: 1.3327mg/g>Mg: 0.7427mg/g>Fe: 0.6234mg/g>Mn: 0.2344mg/g>Cu: 0.0555mg/g>Zn: 0.0435mg/g>Cr: 0.0330mg/g>Pb: 0.0198mg/g>Ni: 0.0054>Cd: 0.0022mg/g The PPT/DCM/HP, FILT/DCM/HP, ETOA/HP and MTH/HP extract showed sensitivity in stephlococcus aureus, FILT/DCM/HP and MTH/HP are sensitive in Meth. resist staph aureous and Acinetobacter sp. The zone of inhibition against the test microorganisms occurred in the four (4) extract at 20mm, 20mm, 20mm and 22mm  for staphylococcus aureus and the extract, PPT/DCM/HP(24mm), FILT/DCM/HP(20mm) and MTH/HP) in streptococcus pneumonia and  PPT/DCM/HP(27mm), FILT/DCM/HP(20mm) and MTH/HP(20mm) for Acinetobacter sp. The results shows that the leaf extract plays significant role in the body metabolic system.
