摘要: 目的:研究不同品种萝卜籽粗脂肪的含量及脂肪酸组成,并利用GC-MS分析不同品种萝卜籽挥发性成分的组成及含量。方法:用索氏提取法测定粗脂肪含量,用溶剂提取挥发油成分,用气相色谱-质谱联用仪进行定性分析,结合计算机检索技术,对化学成分进行分离鉴定,NIST、WILEY化合物谱库检索,应用气相色谱峰面积归一化法测定各成分的相对含量。结果:研究结果表明,萝卜籽含油高(≥30%),油中含不饱和脂肪酸多,具有较大的开发应用价值。

Abstract: Objective: Study on the chemical constituents and contain cents of essential oil and fatty acids from the seeds ofdifferent species of Raphanus Sativus L. with GC and GC-MS. Methods: The essential oils were obtained by the agent extractionand the chemical compositions were separated by GC. The relative contents in the essential oil were determined by areanomalization and NIST and WILEY library searched and 14 were separated and 8 were identified. Result:The research resultexpresses, the seeds of different species of Raphanus Sativus L. contain the oil high( ≥30% ) and contain more the unsaturated fatty acids in the fats, have the bigger development application value.

Key words: seeds of different species of Raphanus Sativus L., fat, fatty acids, chemical constituents, GC-MS
