摘要
 
       本研究有別於一般柑橘類採用冷壓法萃取精油(Essential Oil),而是以水蒸氣蒸餾法萃取,目的是除了精油外亦可得到純露(Hydrosol)。八里產的香水柚和文旦柚皮均萃取到精油並獲得純露,二種柚不含皮的果肉亦單獨蒸餾但僅獲得純露。應用氣相層析儀串聯質譜儀分析:香水柚找到26種揮發性物質構成精油,而其純露中則發現11種化合物構成香味來源;文旦柚則找到29種揮發性物質構成精油,而其純露中發現9種化合物。文旦柚之純露並用Karl Fischer法測得含水量為97%。柚皮精油中以檸檬烯為主要成分,香水柚皮精油含83.84%、文旦柚皮精油則含有61.03%。柚皮純露中香水柚以對硝基苯甲醇33.93%、3-氨基芐醇23.33%為主;而文旦柚則有反式及順式-芳樟醇氧化物及芳樟醇,共占64.25%及α-松油醇占12.72%。香水柚果肉純露分離出3種成份,以肟,甲氧基苯基_45.29%、(Z)-7-十六碳烯33.67%為主;而文旦柚果肉純露則有6種化合物被辨識出,以肟,甲氧基苯基_64.84%為主。

Abstract
 
       This work, apart from using expression to extract Essential Oil (EO) from Citrus, employed steam distillation to extract EO from Pomelo and Hydrosol (HS) were obtained as well.  Buntan Shaddock (BS) and Wentan Pomelo (WP) peels from Bali District, New Taipei City were extracted and EO and HS were acquired.  Both fruits without peel were extracted but only HS were obtained.  GC/MASS were employed to analyze the constituents of EO and HS.  For the BS peel, there are 26 volatile compounds found in the EO, whereas 11 chemicals found in the HS.  In the case of WP peel, 29 volatile compounds were found in the EO, and 9 compounds found in the HS.  The HS from the WP peel has been put thru Karl Fischer method to test the water content, and 97% was the result.  Major constituent of Pomelo Peels’ is Limonene, that of BS is 83.84%, and that of WP is 61.03%.  The HS from BS peel has p-Nitro benzyl alcohol 33.93%, m-Amino benzyl alcohol 23.33% as major ingredients.  Whilst Linalool and cis-Linalool Oxide and trans- Linalool Oxide take up 64.25% of the HS from WP peel, and α-Terpineol occupied 12.72% in the HS.  The HS from the fruit of BS has 3 components, Oxime-, methoxy-phenyl- takes up 45.29% whereas Z-7-Hexadecenal has 33.67% in the HS.  The HS from the fruit of WP has 6 constituents been identified, the majority is Oxime-, methoxy-phenyl-, 64.84% is the figure.
