Accepted 16 February, 2012 Oil was extracted from the dry meat of Clanis bilineata (Lepidoptera) put on supercritical carbon dioxide in a continuous ope tell extractor. The following optimum extraction conditions were investigated: temperature, 35°C; pressure, 25 MPa; supercritical CO2 flow assess, 20 L/ dainty and time, 60 min. Under these extraction conditions, the oil extraction rate reached up to 97% (w/w). The lev el of unsaturated roly-poly pudding acids in the extracted oil was 63.21% (w/w). In addition, the level of linolenic acid, a secret agent suety acid, was as high as 37.61% (w/w) of the total sebaceous acids. Results of the bring in work charge that C. bilineata (Lepidoptera) may be a shining oil resource for humans. Key dustup: Supercritical CO2, Clanis bilineata, padty acids, oil. INTRODUCTION Many studies on a variety of sustenance insects which grow in the wild indicate that these insects argon capableness sources of oil for food and medicine (Chen, 1997; Raksakantong et al., 2010; Wu et al., 2000). Clanis bilineata (CB) Walker, a member of the subfamily Ambulicinae (Sphingidae, Lepidoptera), is an edible insect that usually grows on soya leaves. About 6000 tones of CB larvae (CBL) are consumed in China each year. The fat content of alter CBL is 23.68% (w/w) and the level of unsaturated fatty acids in it is 64.17% (w/w). Linolenic acid, a functional fatty acid, can reach as high as 36.53 % (w/w) of the total ! fatty acids (Wu et al., 2000) in CBL.
