Phyllanthus amarus (family: Euphorbiaceae) is of immense interest due to its wide spectrum of biological activities. In the present study, the standardized 80% ethanol extract of P. amarus was investigated for its modulatory activity on various cellular immune parameters, including chemotaxis of neutrophils, engulfment of Escherichia coli by neutrophils, and Mac-1 expression, in leukocytes isol...

This study was designed to evaluate the gastroprotective and antioxidant effects of aqueous and acetone extracts of Phyllanthus amarus leaves in albino rats. P. amarus extracts (500 and 1000 mg/Kg) as well as cimetidine (100 mg/Kg) was administered orally once a day for two weeks before challenge with absolute ethanol (1 ml/ 200 g body wt). Pretreatment with P. amarus aqueous extract (500 mg/Kg...

The antioxidant property of the 70% aqueous ethanol extract of Phyllanthus amarus roots and its ether-soluble, ethyl acetate-soluble, and aqueous fractions were investigated by various in vitro assays. The root extracts showed higher DPPH, hydroxyl, superoxide, and nitric oxide radical scavenging and reducing power activity. Among all the samples, the ethyl acetate-soluble fraction demonstrated...

The standardized methanol extracts of Phyllanthus amarus and P. urinaria, collected from Malaysia and Indonesia, and their isolated chemical markers, phyllanthin and hypophyllanthin, were evaluated for their effects on the chemotaxis, phagocytosis and chemiluminescence of human phagocytes. All the plant extracts strongly inhibited the migration of polymorphonuclear leukocytes (PMNs) with the Ma...

BACKGROUND Phyllanthus amarus (Schum & Thonn), a plant belonging to the family of Euphorbiaceae is used in Ivorian traditional medicine to treat cardiovascular disorders such as hypertension. However, although this plant has been described as a diuretic agent, the underlying mechanism remains unclear. Therefore, the aim of the present study was to investigate the mechanism action of diuretic ef...

The present paper describes enhancement of lignans, phyllanthin and hypophyllanthin present in Phyllanthus amarus plant. Supplementation was done to enhance secondary metabolites by modifying the media and treatment with different growth promoters and abiotic elicitors to increase the content of hepatoprotective bioactives in immobilized cell cultures, after incubation for 21 days. MS medium wa...

BACKGROUND Current chemotherapeutic drugs kill cancer cells mainly by inducing apoptosis. However, they become ineffective once cancer cell has the ability to metastasize, hence the poor prognosis and high mortality rate. Therefore, the purpose of this study was to evaluate the antimetastatic potential of Phyllanthus (P. niruri, P. urinaria, P. watsonii, and P. amarus) on lung and breast carcin...
