Evaluation of the phytochemical, antioxidant and nutritional properties of <I>Phyllanthus muellerianus</I> leaves

Abstract

Plant-derived preparations and isolated phytochemicals or their model derivatives are now used to treat infectious diseases, especially in the light of the emergence of drug-resistant microorganisms and the need to produce more efficacious and cost-effective microbial agents. This study investigated the phytochemical, antioxidant and antinutrient properties of Phyllanthus muellerianus ethanol leaves extract. The extracts were screened for some antinutrient and phytochemical properties using various laboratory methods. Phytochemical examination of Phyllanthus muellerianus showed the presence of saponin, flavonoid, phlobatanin, tannin, steroids, cardiac glycosides and terpenoids. The antioxidant testing showed the increase in % inhibition of 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH), Nitric oxide and reducing power activity as concentration increases. Antinutrient analysis showed higher amount of phytate than oxalate and a higher amount of alkaloid -than tannin. These properties above may be the reason Phyllantus muellerianus
plant has been reported to be useful in the treatment of several ailments.
