The kernel oil was obtained from Camellia pitardii seed by ultrasound-assisted extraction,and the effects of ultrasonic power,extraction time,extraction temperature and solid-liquid ratio on extraction rate of Camellia pitardii seed kernel oil were studied. The results showed that the optimal conditions of ultrasound-assisted extraction of Camellia pitardii seed kernel oil were obtained by orthogonal experi-ment as follows:solid-liquid ratio 1∶9,ultrasonic power 200 W,extraction time 50 min,extraction tem-perature 55℃. Under these conditions, the extraction rate of Camellia pitardii seed kernel oil was 36. 74%. The analysis results of GC-MS indicated that the main fatty acid composition of Camellia pi-tardii seed kernel oil was oleic acid (78. 68%), palmitic acid (8. 59%), hexadecatrienoic acid (7. 92%),linoleic acid (2. 43%),linolenic acid (1. 17%),stearic acid (0. 81%) and eicosanoic acid (0. 19%),and the content of unsaturated fatty acids was as high as 90. 20%,which had a high application value.
