A New Method of Separation of Citral from Lemongrass Oil

Although many methods are known for the separation of citral from lemongrass (Cymbopogen flexuosus) oil, like fractional distillation, adduct formation and regeneration, the purity and the yield of citral as separated are not satisfactory. A new method for separation of citral in pure form and in near quantitative yield uses the column chromatographic technique. This method may also be adapted for large scale separation of citral and hence can be of commercial importance.

Essential Oils and Microwave Extracts of Cultivated Plants

We have used these two methods to treat different cultivated plants: five Umbelliferae, one Compositae and seven Labiatae. There is a double purpose for this approach. First, we want to determine the advantages and disadvantages of this technique in terms of research. Secondly, we intend to make appropriate comparisons between microwave extracts and essential oils coming from the aerial part of these plants.

Comparative Investigations of the Essential Oil and Volatiles of Spearmint

The objective of this work is to identify the fragrance compounds of this oil and its SPME-headspace by means of gas chromatographic- spectroscopic (GC and GC/MS using different polar and chiral phases) and olfactoric methods (GC-sniffing technique and olfactory correlations) to find out the importance of each single constituent with their specific odor attributes, responsible for the characteristic and pleasant spearmint aroma for the first time.
