ABSTRACT: Phyllanthus (Euphorbiaceae) species have long been used in folk medicine to treat various pathological conditions including liver diseases. Some species of Phyllanthus were found to exhibit hepatoprotective activity against drugs or toxins and this property was majorly attributed to phyllanthin and hypophyllanthin. In this study, we examined the hepatoprotective activity of five different species of Phyllanthus, namely, Phyllanthus amarus, Phyllanthus fraternus, Phyllanthus maderaspatensis, Phyllanthus urinaria, and Phyllanthus Rotundifolius. The extracts were also evaluated for the presence of key phytoconstituents, phyllanthin and hypophyllanthin.
The extracts were evaluated for hepatoprotective activity against tert-butyl hydroxide (t-BH)-induced cytotoxicity using human hepatocarcinoma cells (HepG2 cell line).
Only P. urinaria and P. maderaspatensis exhibited significant hepatoprotective activity as evident from increased cell viability. The HPLC profile revealed that except P. amarus, the other extracts did not contain phyllanthin and hypophyllanthin.
P. urinaria and P. maderaspatensis demonstrated dose-dependent hepatoprotective activity and hence, can provide promising therapeutic interventions against chemical-induced liver damage.
