Hepatoprotective properties: Daily oral feeding with an ethanolic extract of this plant (150mg/Kg) protects hep-atocytes against carbon tetrachloride poisoning (Sarkar A. et al., 1999). A chloroformic extract of Trianthema portulacastrum L. protects male Sprague-Dawley rats against L-diethylnitroso-amine-induced and ph-enobarbital-promoted hepatocarcino-genesis (Battacharya S et al., 1999). These effects could be mediated by trianthenol 1, a carotenoid which was first isolated as antifungal principle (Nawar HR etal., 2001).
Other properties: This plant contains an alkaloid with similar properties to punarvanine from Boerhaavia diffusa (Family Nyctaginaceae; Basu et al., 1947). The diuretic, uterotonic and abortive properties of this plant have not yet been substantiated experimentally.
Uses: The fresh or dried plant of the white variety of Trianthema portulacastrum L. (Trianthema, Indian Pharmacopoeia, 1967) is used in India to promote urination, in the form of a liquid extract (2 in 1, dose 2mL to 8 mL). A decoction of the roots causes mild contraction of the uterus, but in large doses it is abortive. In the Philippines, a decoction of the roots is drunk to promote menses and to abort a pregnancy.
