Data are the mean of three replicates ± SD. Not detected compounds were indicated as nd.
RI by comparison of retention index with those reported in literature.
Std by comparison of the retention time and mass spectrum of available authentic standards.
No-polar column ZB-5; polar column DB-Wax.
a
Identification methods: MS by comparison of the Mass spectrum with those of the computer mass libraries Adams, Nist 11 and by interpretation of the mass spectra fragmentations.
