以无水乙醇为夹带剂，采用超临界CO2萃取荔枝核，并用气相色谱．质谱联用仪（GC—MS）对荔枝核萃取物的挥发性成分进行了分析．结果表明，以无水乙醇为夹带剂超临界CO2萃取荔枝核的萃取率为5．47％，GC—MS鉴定出32种化合物，主要为甾醇类、萜类、不饱和脂肪酸、棕榈酸、脂肪酸酯、芳香醇，相对质量分数分别为38．8％，26.4％，8．60％，7．54％，8．44％，6．11％．和无夹带剂相比，夹带剂无水乙醇可以提高荔枝核的超临界萃取率．

By using absolute ethyl alcohol as extractor, semen litchi was extracted by supercritical CO2 fluid extraction and the extracted volatile components were analyzed by gas chromatography- mass spectrometry （GC-MS）. The extraction yield of semen litchi is 5.74%. Thirty-two compounds were found in the extract including phytosterols, terpenoids, unsaturated fatty acids, hexadecanoic acid, fatty acid ester, aromatic alcohol, with their relative contents reaching 38.8%, 26.4%, 8.60%, 7.54%, 8.44%, and 6.11%, respectively. It is pointed out that absolute ethyl alcohol as extractor improves extraction rate compared with supercritical CO2 fluid.
