中文摘要 | 探討超臨界流體方法在不同壓力下二氧化碳抽取錫蘭肉桂葉香精含量及其化學成 分之變化,化學成分係採用氣相層析儀( GC )之滯留時間( retention time )及氣相層 析 - 質譜儀( GC-MS )之質譜圖鑑定。 精油含量在超臨界流體方法中使用 80, 100 及 120 kg/cm �握坐G氧化碳抽取精油含率依序為 0.81,1.12 及 1.47 mL/100 g。顯示壓力增 加精油收率有增加趨勢。 較水蒸氣蒸餾法之精油含率 1.74 mL/ 100 g 比較略降低。 使用 GC-MS 鑑定出錫蘭肉桂葉精油有 20 個成分, 主成分為 eugenol, 重要成分為 cinnamic aldehyde,linalool,bornyl a cetate 及�` - phellandrene 等,及其它 15 個微量成分 。精油成分含量使用超臨界流體方法在 80,100 及 120 kg /cm �握坐ㄕP壓力下,eugenol 含量依序為 80.83%,84.87% 及 87.45%,eugenol 含量隨抽出壓力增加略有增力,與水蒸 氣蒸餾法 eugenol 含量 92.26% 比較略為減少,其它成分含量變化差異不大。 |
英文摘要 | Variations in yields and components from the leaves of Cinnamomum zey-l anicum were determined under different extraction pressure by using liquid carbon dioxide in a supercritical fluid extraction method (SCF). Components of the essential oils were analyzed and identified by means of retertion times (RT) of gas chromatograph (GC) and gas chromatograph-mass spectrometry (GC-MS) methods. The yields of essential oils from the leaves of C. zeylanicum under 80,100, and 120 kg/cm �� pressures of carbon dioxide extraction were 0.8, 1.12, and 1.47 mL/ 100g, respectively. The yields of essential oil increased with increasing pressure. The yields of essential oils from the SCF method were a little lower than those obtained by using a conventional steam distillation method. Twenty components were identified in the essential oil of C. zeylanicum leaves. The main components were eugenol, cinnamic aldehyde, linalool, bornyl acetate, and �` - phellandrene. etc. Other minor componeents, such as �` - pinene, camphene, �� -pinene, limonene, 1,8-cineole, terpinolene benzaldehyde, �� - caryophllene, 4-terpineol, �` - terpineol, borneol, benzyl acetate, geraniol, 3-phenyl propanal, and isoeugenol (Table 2), were also identified. The major component of the essential oil of C, zeylanicum leaves from both the SCF and steam distillation methods was eugenol. The content of eugenol under 80,100 and 120 kg/cm �� pressure from the SCF method were 80.83, 84.87 and 87.45 mL/100 g of the total, respectively. The content of eugenol increased with increasing pressure. By using the SCF method, the contents of eugenol (80.83% to 87.45%) were lower than those of using conventional steam distillation method (92.26%). There was little difference in the contents of each component with respect to different extraction pressures of the SCF method. |
