采用索氏提取法、超声波辅助提取法和超临界CO2萃取法对产自江西莲花县的油茶籽进行提油实验。对得到的油茶籽油进行理化性质测定，并采用GC-MS分析了油茶籽油的脂肪酸组成，比较不同提取方法所得油茶籽油的品质差异。结果发现：不同提取方法得到的油茶籽油脂肪酸组成及含量存在差异，对油茶籽油的营养价值产生影响。从脂肪酸组成的角度评价，超临界CO2萃取法所得的油茶籽油营养价值更高。

The oils were extracted from oil-tea camellia seeds in Lianhua county in Jiangxi province by methods of Soxhlet extraction,ultrasonic-assisted extraction and supercritical carbon dioxide extraction. The physicochemical properties of the extracted oils were measured and the fatty acid compositions were analyzed by GC-MS to compare the qualities of the oil -tea camellia seed oils extracted by different methods. The results showed that the fatty acid compositions and contents had significant differences among the oil-tea camellia seed oils extracted by different methods, which had impact on the nutritional value of oil-tea camellia seed oils. From the perspective of fatty acid composition,the nutritional value of oil-tea camellia seed oil obtained by supercritical carbon dioxide extraction method was the highest.
