用GC-MS分析不同方法提取的茶油脂肪酸（GC-MS) . GC-MS Analysis of Fatty Acids from Tea-seed Oil Extracted by Different Methods

Abstract

Seed oil from Camellia oleifera extracted with different methods (supercritical CO2, microwave, ultrasonic, and squeezing) was analyzed by GC-MS. Chemical composition of the seed oil extracted with the three methods was similar except squeezing. However, vitamin E and squalene were not found in the constituents extracted by squeezing. It is suggested that the extraction with supercritical CO2 is an ideal method by which the oil is up to the first degree of national standard. Physical and chemical properties, and the constituents of the oil extracted by these methods are tabulated.
