Abstract
The purpose of this study was to investigate the effect of Damavand volcanic ash on the morphological and physiological characteristics of beans as a factorial experiment in a completely randomized design. The results showed that the highest dry leaf weight was observed in 100 mg/L treatment per liter of volcanic ash (0.0099 g). The results also showed that the optimal sugar content of the soluble sugar at 100 mg/L of volcanic ash was 0.650 (mg/g D.W.). The highest protein content and optimal peroxidase activity were observed with 0.68 (mg/g F.W.) and 0.082 (A470/mg/protein), respectively. Therefore, it can be argued that volcanic ash may increase plant growth and biosynthesis of organic compounds such as iron and aluminum.

Abstract
Punica granatum leaf extracts have been used since time immemorial in traditional medicines. It is used for its antioxidant properties. Green nanoparticle synthesis is an emerging field which has opened an entirely different scope for medicinal formulations. It has been reported by many users that the green nanoparticles are more effective medicines as compared with their simple extracts. Thus, in order to evaluate these speculations, the present work was undertaken to assess the hepatoprotective activity of silver nanoparticles synthesized using aqueous leaf extract of Punica granatum in comparison with the aqueous extract. After CCl4 intoxication the serum bilirubin total increased significantly (p<0.05) and the total protein level decreased significantly (p<0.05) as compared with the control group; in addition, alkaline phosphatase activity, aspartate aminotransferase activity and alanine transaminase activity increased significantly (p<0.05). The CCl4 intoxicated rats were treated with aqueous leaf extract and synthesized nanoparticles, the results clearly revealed that the aqueous extract of Punica granatum showed hepatoprotective effect, as the liver profile altered by CCl4 toxicity, recovered to normal control values. Moreover, the nanoparticles synthesized using aqueous leaf extract of Punica granatum were comparatively more effective as hepatoprotective agent than the aqueous extract of Punica granatum.
