ESTIMATION OF COLCHICINE:In the first method for extraction (Method 1)[1]‚ 0.5 g of powdered plant material was extracted twice with 25 ml of petroleum ether with frequent shaking for 1 h‚ followed each time by filtration. The solid residues were air dried and then extracted with 10 ml of dichloromethane at room temperature for 30 min with frequent shaking. Then 10% solution of ammonia (0.5 ml) was added to the mixture with vigorous shaking for 10 min; the mixture was left undisturbed for 30 min

Explain the observed solubility properties of trimyristin. The fatty acids are responsible for its solubility in ether and insolubility in acetone. The fatty acids are long non-polar hydrophobic carbon chains and can only dissolve in other non-polar solvent like diethyl ether because

Introduction: The theory behind the extraction of a solution containing benzoic acid‚ cellulose‚ and methyl orange involves many components pertaining to the fundamental ideas of solubility and polarity. Using the concepts of like dissolving like and acid base reactions‚ a solution of organic acid (benzoic acid)‚ a water soluble compound cellulose‚ and an organic soluble compound methyl orange‚ can be separated and benzoic acid can be isolated by a method of extraction. At the fundamental
