ObjectivesTo analyze the presence of estersPrediction of most suitable solvent for the extraction of leaf constituents Conversion analysis.

25-04-20154METHODOLOGY The method followed can be categorized asSample Collection Sample from BITS PILANI campus.Sample was dried for 6 days, ground and sieved.Stored at 4oC.2. Extract PreparationHexane and Ethanol were used.250ml of solvent to 50g of sample. Concentrated to one eighth of initial volume.25-04-20155METHODOLOGY3. SaponificationOil was tested to determine Saponification value.Saponification Value = (sample titre blank)*56.1*NKOHSaponification Value = (3*56.1*1000)/((3*mean MW)+ 39.08)4. TransesterificationBase Catalysed Esterification was performed.Reaction Time: 4h Settling Time: 24h
