Abstract: In this research, the dry silkworm pupaes, which are one kind of the silk industry product were used to extracting pupal oil. The results showed that the optimize technique of extracting condition was temperature 38 ℃, time 2 hours, solvent 4 ml/g and vibration-rotationvelocities 160 r/min. The extracting rate of pupal oil was measured about 28.17%.

Key words: silkworm, pupal oil, extracting technics, optimizing
