中文摘要 | 利用氣相層析和氣相層析-質譜聯用技術分析了不同產地 (河北、陝西及山東) 的中國芥茉揮發油的化學成份。從河北芥茉油中,我們鑒定了22種化合物,佔總精油的89.6%,河北芥茉油的主要成份是:烯丙基異硫氰酸脂 (54.8%)、二烯丙基三硫醚 (9.4%)、二烯丙基硫醚 (5.59%)和3-T烯基 異硫氰酸脂 (4.8%)。從陝西芥茉油中,我們鑒定了14種化合物,佔總精油的94.5%,陝西芥茉油的主要成份是:烯丙基異硫氰酸脂 (68.8%)、二烯丙基三硫醚 (7.8%)和3-丁烯基異硫氰酸脂 (49%)。從山東芥茉油中,我們鑒定了15種化合物,佔總精油的94.3%,山東芥茉油的主要成份是:烯丙基異硫氰酸脂 (61.3%)、二烯丙基三硫醚 (9.7%)和3-丁烯基異硫氰酸脂 (5.9%)。從所獲得的分析結果來看,中國芥茉油的成份均是由異硫氰酸脂和硫醚所構成的。 |
英文摘要 | The composition of essential oils in the seeds of Brassica juncea (L.) Coss., grown in Hebei, Shaanxi and Shandong Province was determined by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). We have identified twenty-two compounds constituting 89.6% by weight of the mustard oil from Hebei Province. The main components were allyl isothiocyanate (54.8%), diallyl trisulfide (9.4%), diallyl sulfide (5.5%) and 3-butenyl isothiocyanate (4.8%). Fourteen compounds representing 94.5 % by weight of the mustard oil from Shaanxi Province were identified. They were allyl isothiocyanate (68.8%), diallyl trisulfide (7.8%) and 3-butenyl isothiocyanate (4.9%). Fifteen components were identified accounting for 94.3% by weight of the mustard oil from Shandong Province. Major constituents were allyl isothiocyanate (61.3%), diallyl trisulfide (9.7%) and 3-butenyl isothiocyanate (5.9%). |
