^aRI, retention indices as determined on TR-5 capillary column using homologous series of n-alkanes.

^bMethods of identification: MS, by comparison of the mass spectrum with those of the computer mass libraries; RI, by comparison of RI with those from the literature.

^c(%), relative percentage obtained from peak area.
