大麦虫（Zophobsmorio L.）幼虫生长过程中维生素E含量变化的研究

大麦虫是一种高含油的新型资源昆虫。利用高效液相色谱法测定了大麦虫幼虫体内维生素E的含量，并对其随日龄、体重、体长的变化趋势进行了分析。结果表明：大麦虫幼虫含有丰富的α 维生素E和少量的δ、β、γ 维生素E，α 维生素E的变幅在168.64~264.57 mg/kg之间。在45~87日龄期间，大麦虫幼虫的日龄、体重、体长三者之间有极显著的线性相关（R2≥0.964，P＜0.01）。α 维生素E含量与这三项指标有极显著的二项式曲线相关，其与体长相关性最高（R2=0.640，P＜0.01），当体长达5.1 cm时，幼虫体内α 维生素E含量最高，是生产高维生素E产品结束养殖的最佳时间。

Variation of Vitamin E Content of Zophobsmorio L. Larvae During the Course of Growth

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.
