8,9-Epoxy brevifolin (EBF) is a novel compound isolated from Phyllanthus simplex Retz (P. simplex) and has been demonstrated to possess a hepatoprotective effect. The purposes of the present study were to examine the in vivo pharmacokinetics and tissue distribution of EBF in rats using a liquid
OBJECTIVE
To investigate the effect of protecting liver of brevifolin and 8,9-single-epoxy brevifolin of Phyllanthus simplex.
METHODS
Rats were administered with CCl4 (ip) or alcohol (ig) to establish acute or chronic liver injured model, respectively. ALT, AST and TBIL in serum were measured using
Aldose reductase (AR) inhibitory activity-directed fractionation of the 70% ethanolic extract of Para-parai mí, Phyllanthus niruri, has led to the isolation of three active components, ellagic acid (1), brevifolin carboxylic acid (4) and ethyl brevifolin carboxylate (5). Among them, 1 showed the
Phyllanthus niruri L. is a widespread tropical plant which is used in Ayurvedic system for liver and kidney ailments. The present study aims at specifying the most active hepatoprotective extract of P. niruri and applying a bio-guided protocol to identify the active compounds responsible for this
Studies on the chemical constituents of Phyllanthus urinaria and its antiviral activity against hepatitis B virus were completed. Eleven compounds have been isolated. Two of them are new compounds methyl ester dehydrochebulic acid and methyl brevifolin carboxylate. Antiviral experiments on HBsAg in
BACKGROUND
This study was designed to obtain the chemical fingerprint and to investigate the effect of Phyllanthus urinaria on telomerase activity and apoptotic pathways in the human nasopharyngeal carcinoma cell line (NPC-BM1).
METHODS
The polyphenol compounds in P. urinaria were investigated by
