Chrysalis oil, an insect fat obtained from the spent silk worm pupae, Bombyx mori, is a by‐product of sericultural industry and represents a potential source of 1750 tons of linolenic‐rich oil per annum for India. Fatty acid and triglyceride compositions of chrysalis oil have been determined by the combination of the techniques of lower temperature segregation, lipolysis, thin layer and gas liquid chromatography. Percentage contents of the component acids are: C 14:0 , 0.6; C 16:0 , 19.3; C 18:0 3.9; C 18:1 , 17.7; C 18:2 , 9.8, and C 18:3 , 48.7. Major component triglycerides are, LLnLn, 5.2%; PLnO, 6.4%;OLnLn, 9.6%; LnLnLn, 10.5% and PLnLn, 14.0% (P, palmitic; O, oleic; L, linoleic and Ln, linolenic acids. On low temperature crystallization, Chrysalis oil yielded two fractions amounting together to 40% of the total with composition quite similar to that of linseed oil.
