The aim of the present study was to isolate hepatoprotective component from Urtica dioica Linn. (whole plant) against CCl4-induced hepatotoxicity in-vitro (HepG2 cells) and in-vivo (rats) model. Antioxidant activity of hydro alcoholic extract and its fractions petroleum ether fraction (PEF), ethyl acetate fraction (EAF), n-butanol fraction (NBF) and aqueous fraction (AF) were determined by DPPH...

Introduction: Paracetamol is a potent hepatotoxin and may cause severe acute hepatocellular injury. The present study was intended to assess the hepatoprotective potential of Caralluma umbellata Haw. (Asclepiadaceae) against paracetamol induced hepatotoxicity in vitro and in vivo experimental models. Methods: Preliminary analysis for antioxidant and hepatoprotective property was evaluated for m...

Two new lanostane triterpenoids, 20-hydroxyeuphorbol-7-one (1) and 15α-hydroxyeuphorbol-7,11-dione (2), together with four known triterpenoids, euphorbol-7-one (3), friedelin (4), stigmast-4-ene-6α-ol-3-one (5), stigmasta-4-en-3,6-dione (6), were isolated from ethanol extract of the branches and leaves of Polyalthia obliqua. The structures of 1 and 2 were elucidated on the basis of extensive sp...

The immunomodulatory bioassay-guided fractionation of the oleogum resin of frankincense (Boswellia carterii Birdwood) resulted in the isolation and identification of 9 compounds; palmitic acid and eight triterpenoids belonging to lupane, ursane, oleanane, and tirucallane skeleta were isolated form the resin. These triterpenoids are lupeol, beta-boswellic acid, 11-keto-beta-boswellic acid, acety...

The ethyl acetate soluble fraction from the roots of Sanguisorba tenuifolia was found to have a hypoglucemic effect in alloxan-induced diabetic rats. Two new triterpenoids, identified as 2-oxo-3β,19α-dihydroxyolean-12-en-28-oic acid β-D-gluco-pyranosyl ester (1) and 2α,19α-dihydroxy-3-oxo-12-ursen-28-oic acid β-D-glucopyranosyl ester (4) were isolated from this fraction, along with thirteen kno...

Azadirachta indica had ample therapeutic action since many years. Hepatoprotective effect of methanolic and aqueous extracts of azadirachta indica leaves was evaluated using Male Wistar rats. Result indicate that the plant good potential to act as hepatoprotective agent.
