The composition of the laboratory-prepared essential oils fi om Uruguayan N
ova and Satsuma mandarins has been studied. The volatile fraction was analy
zed by HRGC and HRGC/MS (quadrupole); 79 and 73 components were identified
in Nova and Satsuma mandarin oils, respectively. The linear retention indic
es were calculated for almost all identified components on two different st
ationary phases. The enantiomeric distribution of beta-pinene, sabinene, li
monene, linalool, and cr-terpineol was studied by multidimensional gaschrom
atography (MDGC). Polymethoxylated flavones, present in the nonvolatile res
idue, were analyzed by normal-phase HPLC.
