Analysis of leaf oils from four varieties of sweet orange by combined gas chromatography‐mass spectrometry

Abstract: The leaf oil of four varieties of Algerian sweet orange were examined by GC and GC-MS. In total, 68 constituents were identified from which 50. 54, 38 and 43 compounds were found to be present in the leaf oils of Washington-navel, Valencia, Sanguine and Portuguese varieties respectively. Of the 68 constituents, 34 were characterized in sweet orange leaf oil for the first time.

“…Comparison of our data with those in the literatures revealed some inconsistencies with previous studies (Lota et al, 2001;Baaliouamer et al, 1988). It may be related to cultivar, rootstock and environmental factors that can influence compositions.…”

“…The method of calculation of the yield was different in the two studies; thus, it is not possible to compare the values. The LEO yield is generally 1.5 to 2 times lower than what is observed in the literature [45][46][47][48]. However, in most publications, the LEO yield value is given in v/w, whereas in our study, it is expressed in g/100 g of leaves.…”

“…No details are given in these articles on the method of measuring the volume of EO; it can only be assumed that, given the accuracy of the provided value (to one decimal point), it was evaluated on the graduated column of the Clevenger where the oil is recovered. Apart from the values, the differences in yield between varieties are sometimes comparable; for example, the cultivar 'Valencia' produces 1.6 times more oil than 'Washington navel' and 1.3 times more oil in our study [45]. Furthermore, it seems that thicker skin cultivars have a lower yield than thinner skin cultivars, although this is calculated with respect to the dry mass of the skin.…”
