Anti Inflammatory Activity Anti-inflammatory effect of C. rotundus was studied and reported by various workers. The 70% alcoholic extract of C. rotundus leaves possessed significant anti-inflammatory activity against carrageenan induced oedema and formaldehyde induced arthritis in albino rats (Sundaram et al.‚ 2008). The methanolic extract of C. rotundus rhizome was reported to have anti-inflammatory activity against carrageenan induced paw edema in rats. The results showed that methanolic extract

After 60 minutes‚ the solution was allowed to cool to room temperature. 1 mL of ether was added to the reaction vial. The two layers were mixed and the organic portion (layer on top) was removed and placed in a 1 dram vial. This was repeated once. Next‚ 5% aqueous

The Friedel-Crafts acylation reaction created acetylferrocene and diacetylferrocene‚ using phosphoric acid as a catalyst for the reaction between acetic anhydride and ferrocene (once applying heat). During column chromatography‚ a solution is passed through a filtration system

the degree of unsaturation. For C5H12O‚ the degree of unsaturation was zero‚ which means that the compound only has single bonds. Knowing that there were only single bonds led to the assumption that the O in the compound was either an alcohol or an ether. The IR spectrum helped in determining which functional group was present. The peak that determined the identity of the functional group was peak A at 3352.71 cm-1. The peak corresponds to an alcohol functional group because alcohol spectra have an

Both of the writers make me feel sympathy for the main characters because the main characters are both still in their youth and they both face the same fate – death. Although the characters are portrayed in very different situations‚ both writers show how powerless they are to avert their fate. By having an accident or tragedy in the pieces‚ the writers make the reader feel compassion because it is not the central characters fault. From saying that the boy was ‘a child at heart’ whilst ‘doing a
