A NEW METHOD OF ESTIMATION OF CITRAL IN LEMON GRASS OIL BY PHYSICAL SEPARATION OF CITRAL
At present the usual method of estimation of citral in lemon grass (Cimbopogen flexuosus) oil is by sodium bisulphite adducting. However this method cannot be expected to give correct value since other aldehydes and methyl ketones, known to be present in lemon grass oil will also get adducted. A new method of estimation for citral is now developed which avoids this defect, by physically separating citral quantitatively in pure form from lemon grass oil samples by column chromatography. This method yields very reliable results, since the citral present is physically isolated quantitively from the oil in pure form. The above method involving the use of no chemical, can also be adopted as an excellent method, superior to all the other methods known for the isolation of pure citral. Hence this method can be of commercial value for the production of pure citral.
