Wastewater sources contain enormous amounts of nutrients for plant growth. This study aimed to define the metal accumulation in goosefoot (Chenopodium album L.) wastewater use agricultural irrigation and evaluate risks this human health. The present research was performed field conditions Khushab, Pakistan. Cd, Cu, Cr, Fe, Zn, Ni, Mn concentrations were determined with analysis using Atomic Abs...

Fractionation of crude petroleum ether extract of the leaves of Chenopodium album Linn lead to the isolation of β-sitosterol (1), lupeol (2) and 3 hydroxy nonadecyl henicosanoate (3). Their structures were elucidated by spectroscopic methods such as UV, IR, NMR and LCMS. Compound 2 and 3 were isolated for the first time from this plant.
