摘要
采用水蒸气蒸馏法和离子液体添加剂辅助提取陕西姜黄中的挥发油,气相色谱-质谱(GC-MS)测定姜黄挥发油的化学成分。通过正交实验优化,确定离子液体辅助水蒸气蒸馏法提取姜黄挥发油的提取率优于不加离子液体的水蒸气蒸馏法,其最佳工艺为m(姜黄)∶V(提取液)=1∶20 g/mL,筛孔0.25 mm,提取时间5 h。不同批次的陕西姜黄挥发油含量均大于0.035 mL/g。姜黄挥发油主要组分为烯酮、烯烃、芳香烃类物质,其中姜黄二酮、吉马酮、姜黄烯等含量较为丰富,该研究可为姜黄挥发油及其相关制剂的质量控制提供参考。
The volatile oil from turmeric was extracted by steam distillation and ionic liquid additive.The chemical components of curcuma oil were determined by gas chromatography-mass spectrometry(GC-MS).Through orthogonal test optimization, it was determined that the extraction rate of volatile oil from turmeric by steam distillation assisted with ionic liquid was obviously better than that of extraction only by steam distillation without ionic liquid, and the optimum process of extracting volatile was as follows: ratio of material to liquid 1∶20 g/mL,sieve diameter 0.25 mm, extraction time 5 h.And the content of volatile oil in different batches of turmeric was more than 0.035 mL/g.Although the addition of ionic liquid had little effect on the extraction rate of the volatile oil from turmeric, the components of the volatile oil were increased.The constituents of volatile oil in turmeric are complicated, which are mainly ketene, olefin and aromatic hydrocarbons, among which the contents of curdione, germacrone, curzerene, etc.are abundant.This study can provide scientific reference for the quality control of volatile oil in turmeric and its related preparations.
