Abstract:

Zophobsmorio L. is a new kind of resource based insect with high oil content. In this study, the content of vitamin E in Zophobsmorio L. larvae was determined by HPLC and the varied trends of vitamin E in larvae according to age, body weight and body length were analyzed. The results indicated that the larvae contains rich α vitamin E and a small amount of β, δ, γ vitamin E, the content of α vitamin E ranged from 168.64 mg/kg to 264.57 mg/kg. At the period of 45~87 days of age, there were significant linear correlations either between age and body weight, or age and body length, all the square of correlation coefficients were more than 0.964 (P<0.01). The relationship among vitamin E of larvae and these three indexes significantly met the binomial curve (P<0.01), the maximum correlation existed between vitamin E and body length, the square of correlation coefficient was up to 0.640 (P<001). The larvae could have the most α vitamin E content when the body length reached 5.1cm. So it was the best time to end the farming and process the larvae into production with high vitamin E content.
