GC-MS Analysis of Fatty Acids from Tea-seed Oil Extracted by Different Methods

Abstract:

Seed oiI from Camellia oleifem extracted with different methods(supercritical CO₂，microwave，ultrasonic，and squeezing)was analyzed by GC-MS．Chemical composition ofthe 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．
