Essential oil obtained from carrot (Daucus carota) seeds by hydrodistillation was analyzed by gas chromatography-mass spectrometry (GC-MS). A total of 51 compounds, accounting for 97.8 % of the total oil were identified. Carotol, a sesquiterpenoid was found to be the major compound present in the carrot seed essential oil while the other compounds were daucol, daucene, b-cubenene, b-farnesene, etc. Carotol was isolated from carrot seed essential oil by column chromatography which was chemically transformed into daucol, carotol ether, 4-chloro carotol and carotol amide. The structures of these compounds were elucidated on the basis of FTIR, 1H NMR and 13C NMR.
采用气相色谱-质谱法(GC-MS)分析了通过水蒸馏法从胡萝卜(Daucus carota)种子中提取的精油。共鉴定出 51 种化合物,占精油总量的 97.8%。胡萝卜籽精油中的主要化合物是胡萝卜素(一种倍半萜类化合物),其他化合物包括芥子醇、芥子烯、b-芘、b-法呢烯等。胡萝卜籽精油中的胡萝卜素是通过柱层析法分离出来的,并通过化学反应转化成了芥子醇、胡萝卜素醚、4-氯胡萝卜素和胡萝卜素酰胺。根据傅立叶变换红外光谱、1H NMR 和 13C NMR,阐明了这些化合物的结构。
