Studies on volatile compounds of different varieties in Brassica napus L.
To compare volatile components of different varieties, volatile compounds were extracted by water distillation approach frou entire plants 25 days before maturation in Brassica napus L and assayed by capillary gas Chromatography-mass spectrometry (GC-MS). A total of 107 different components were identified. Volatile profile of four varieties Tapidor, Ningyou No.7, NJ5412 and Heza No.7 included 57,51,45 and 43 compounds, respectively. 15 compounds were common among the 4varieties, including high-content phytol and oleic acid, also including β-damascenone,β-ionone and myristic acid, etc. Volatile profiles were quantitatively and qualitatively different among the varieties. In Tapidor, there were 2 kinds of isothiocynate with relative content 0.36％, but there were 7 kinds of isothiocynate with relative content 2.43％ in Ningyou No.7. As to linoleic acid content, it was 18.55％ in Ningyou No.7, but less than 2％ in the other. As an exception, NJ5412 did not contain insect attractant cis-3-hexenol. Totally, different varieties had different volatile profiles that probably are basis of genotype selection.
