Background: Plants belonging to the genus Euphorbia were used traditionally to treat several health disorders and diseases. Objective: the aim of this study is evaluation of secondary metabolites and hepatoprotective activity of the ethyl acetate fractions of the aerial parts of Euphorbia paralias (Ep) and Euphorbia geniculata (Eg). Materials and Methods: UPLC-ESI-MS/ MS technique was used for identification of the secondary metabolites. The hepatoprotective potential of the two plants was evaluated for the first time in male rats with thioacetamide induced liver injury. Results: A total of 32 secondary metabolites were identified in the ethyl acetate fractions of the aerial parts of both species. Ellagitannins such as tetragalloyl hexoside, ellagic acid, gallic acid, and flavonoids such as kaempferol-3-O-β-(6{\textquoteright}{\textquoteright}-galloyl-Oglucopyranoside), quercetin glycosides (glucoside and arabinoside) were found to be the major components in Ep whereas flavonoid glycosides including quercetin rutinoside, quercetin glycosides (glucoside, arabinoside and rhamnoside) and kaempeferol glycoside derivatives were highly abundant in Eg. Administration of thioacetamide resulted in marked elevation in liver enzymes, elevation of lipid profile and alteration in oxidative stress parameters. While pretreatment of rats with Ep and Eg ethyl acetate fractions significantly attenuated the hepatic toxicity through reduction of liver biomarkers, improving the redox status of the tissue and so brought down the serum biochemical parameters and lipid profile nearly toward the normal levels. Conclusion: The studied fractions show hepatoprotective potential with promising value as hepatoprotective drugs of natural origin in comparison with silymarin as the standard hepatoprotective drug.

Background:Potentilla mooniana Wight. (PM) (Family: Rosaceae) is a plant commonly grown at the higher altitudes (1500\–3660 meter) of the lower Asian continent and is traditionally used to treat gastric and mouth disorders. The present study was aimed to scientifically develop a standard monograph for PM on the basis of pharmacognostical and phytochemical aspects. Methods: Pharmacognostically the roots were analyzed following the standard parameters prescribed under WHO guidelines and Indian Herbal Pharmacopoeia. Results: Morphologically, the roots are cylindrical, dark brown and astringent to bitter in taste. Histologically, the root section showed the formation of secondary growth with wood formation and central lignified xylem vessels. Physicochemical standards quantified includes foreign organic matter (1.20\% w/w), loss on drying (9.66\% w/w), total ash (12.65\% w/w), acid insoluble ash (4.65\% w/w), water soluble ash (0.5\% w/w), alcohol soluble extractive (21.3\% w/w), water soluble extractive (14.6\% w/w), foaming index (142.85), swelling index (6.5), haemolytic index (37.77). Quantification of pesticide residue content and heavy metals such as Pb, Cd, Zn and Hg was analyzed and were found to be present within the permissible limits. Powdered drug showed the presence of lignified xylem vessels with scalariform and spiral thickenings, tracheids, starch grains and fibres. Phytochemical screening showed the presence of phenolics, tannins, flavonoids, steroids, saponins, sugars, and amino acids. Quantification of phytoconstituents were also investigated such as phenolics (84.15mg/g tannic acid equivalent, TAE), tannins (65.31mg/g TAE), flavonoids (9.53mg/g rutin equivalent, RE), flavonols (2.01mg/g RE), saponins (20.75mg/g diosgenin equivalent, DE), sapogenins (15.4mg/g DE) and carbohydrates (56.8mg/g D\–fructose equivalent). TLC of the root extract was also analyzed in the present study. Conclusion: In conclusion, the diagnostic characters obtained from the roots of P. mooniana will provide beneficial information in identifying and comparing this plant from other closely related Potentilla species.
