中文摘要 | 本研究利用氧化鋁管柱區分、分離正己烷萃取之椪柑皮精油,以正己 烷、氯仿、丙酮及甲醇依序溶洗。各區分部分之香氣成分為:正已烷區分部分(回 收率為83.85)以碳氫化合物為主(99.28),其中limonene佔92.12。此區分具有平淡 檸檬香氣。氮仿-1區分部分(回收率為0.92)以醇類化合物含量最多(86.66),其它 香氣成分如酸類、醛類亦高(7.07及3.67)。氯仿-2區分部分(回收率為0.53)主要為 醇類(92.86),醛類含3.1,酸類佔1.52。此兩部分(氯仿-1、氯仿-2)皆具柑橘水果 之濃香和甜味。丙酮區分部分(回收率為2.07)以碳氫化合物為主,此部分香氣平 淡。甲醇區分部分(回收率為1.21)則以醇類、醛類、酸類和酯類較多,亦具柑橘 香味。 |
英文摘要 | This study used aluminum oxide column to fractionate essential oil of C. poonensis hort.peels by n-hexane, chloroform, acetone and methanoi sequential elution. The yields of n-hexanefraction was 83.85, and the main components of this fraction was hydrocarbon (99.3), particularly enriched with limonene (92.1), providing the light odour of lemon; the yields of chloroform-1 fraction waaas 0.92, this fraction mainly enriched with alcohol (86.66), contain acidsand aldehydes 7.1 aand 3.67, respectively, having the sweet citrus smell; the yields ofchloroform-2 fraction was 0.53, this fraction mainly enriched with alcohols (92.8), aldehydes (3.1) and acids (1.52), having the deep sweet citrus and flower like smell; the yields of acetonefraction was 2.07, this fraction mainly enriched with hydrocarbon (94.1), providing the lightodour of lemon; the yields of methanoi fraction was 1.21, this fraction enriched with alcohols(68.2), aldehydes (15.04), esters (8.12), hydrocarbon (5.59) and acids (3.1), this fraction having the good citurs smell. |
